Questions our customers have asked

What size is this spacer?
It is an angled spacer. 7/16th to 3/8th.
Wouldn't you need 2 oem plenum gaskets?? One for under the spacer and one for above it?
We include one gasket specifically for the top of the spacer. We reuse the the lower metal gasket. If you wanted to add a fresh lower gasket we have them available here: (Link)
I bought this set a while back and now I cant seem to find the rubber pieces. I see you have the gasket priced at $28.00 which i will likely need but I also need the (6) M6 Washers w/ Bonded Seal. Are these sold separately? Are you guys able to source them?
Hi Will thanks for the inquiry! We now have these available for online purchase at the link below. We have these in stock and ready to ship. Thanks for your patience! (Link)
i bought this 4 years ago, ive had the plenum off a few times now. Can i purchase just the washers with rubber on them? mine are shot. thanks
You sure can Joe! Follow the link below and it will take you to the bonded washers. Thanks! (Link)

Honestly i was a bit weird to install, i had to reuse some of the factory bolts which was tricky to play with. but you can notice a difference in the power. it’s very torquey now. It accelerates much faster; all though if you get a tune it’ll do a whole lot more of a difference than without it.

Where do I even begin, this plenum spacer REALLY opens up the Vq35de engine. Owning my g35 for 4 years I can’t believe I didn’t have this installed all this time, the engine Loves this mod, almost like before it was struggling and now I really can tell the difference. The car pulls harder, runs colder and on the first test drive I had a big smile on my face. This mod is a MUST for a VQ35DE.

Super easy install, fits perfectly, and comes with a new set of longer bolts. It gives a really nice low end growling noise which sounds so good. You can also feel a nice increase in throttle responsiveness and a maybe a little extra acceleration power.

Drove the car pretty easy for about 100 miles to really let the gaskets take seat! Afterwards I opened it up on the highway and could easily feel the difference in throttle response! This spacer really wakes that sleepy G35. I'm using the spacer, Z tube, JWT pop charger with DC headers and Kinetex High flow cats! Great combo for any VQ35DE

There are cheaper ones made of plastic for $100. Bought this one for the durability of aluminum. Only gave it 4 starts due to price of over $200 on special and no installation instructions. Installation was not difficult was a pain to hold washers under the strut tower brace of my 05 Z.

February 5, 2023
It’s a good spacer, I’m not sure I noticed a power increase necessarily (because I did test pipes and a tune around the same time). Its nice quality felt solid, my tuner told me it was a good idea along with stock intake (my 03 made 270 whp) but I’m only giving 4 stars because the washers provided are not good enough to push the strut bar up, I wish it came with actual spacers and not washers.

Part is Very good quality. It did not however come with instructions in the box and you have to re-use some of your factory bolts. The bolts on the back(throttle body side. That you re-use seem short so I recommend you pick up some a little longer from a hardware store before you strip out your lower intake plenum.

Shipping was fast with everything inside the box. Installation is super easy. The quality of the part is great. The performance of my 06 g35 coupe has gotten (a bit) quicker due to more air flow. In particular, living in an area where it’s extremely hot and humid is where the plenum spacer can perform at its best to provide suitable HP/WP.

Super swift delivery to Australia and well packaged. The installation instructions that can be downloaded from Z1 make the process very simple. I wasn't sure which bolts should have the small washers and these can cause some bolts to be too short. I took the opportunity to replace the spark plugs (an onerous task) so I am not sure that the perceived pep is due to those or the spacer. It doesn't matter since I wanted to perform the spacer mod and the Z1 spacer is good quality. My bum dyno feels that the car is peppier at around 4,000 rpm. This might be the placebo effect but again it doesn't matter. Spend the money on the one you love! :)

Working great so far for me, definitely woke my G up a bit. Had done a few pulls vs identical car (air intake) vs (air intake w/ z1 plenum spacer) an let's just say it pulls harder up top. For a thrilling drive, I would recommend this product. Or save up for the kinetix honestly. It's up to you.

Everyone knows the first modification someone should do to their Z or G is a plenum spacer. I made the mistake of ordering one off ebay by Blox, it was about half as much as this one but broke within a week or so. Z1 includes the additional plenum gasket as well (I don't think any other companies do). You can IMMEDIATELY feel the difference once the spacer is installed. Strong to decent gains throughout the entire RPM range. Get this with other intake/exhaust modifications to really bring the car to life. Great product as always from Z1.

Did this in 1 afternoon, comes with everything you need, sounds better and opens up midrange power. You’ll need to mess with the strut bar because if not, the plenum will touch it when revving so you’ll need to adjust it. I was able to even reuse the plastic engine cover after messing with the strut bar for a couple miniutes.

Awesome product!! I always said the Z should have come with this! Definitely allows a bigger opening for better breathing.

Wasn't sure whether this was worth it but when I found out it works even better for revups I felt like I had to get it and I don't regret it. Quick solo installation and I am feeling more responsive throttle but that's including other mods as well.

I upgraded to this from a plastic blox spacer and what a difference in quality and fitment The only thing i wish is that it came with all new hardware for the plenum instead of re-using sone of the oem bolts. But no big deal!

I bought this 1/2" spacer for a 2006 Nissan 350z, and after about an hour, it was installed. Upon starting my Z, it sounded more throatier, and when I took off, I immediately felt a difference in the acceleration, especially in the mid range. I am very well pleased with this product, and the instructions were very on point. Don't forget, buy some copper permatex, and put a good seal on top of the existing gasket before placing the spacer in. After placing two washers on each strut bolt, my strut bar went over my engine without touching my hood. This is the first of many upgrades.

Great quality spacer. Backed up with the Dino benchmark (see the Banana Build vid). I also paired this with cold air in-take and Motordyne’s ISO Thermal Kit… detailed Instructions easy to follow. Most of the time was spent cleaning the lower and upper plenum prior to reassembly.

The spacer is very well designed and manufactured. A few suggestions though: 1) Add to the instruction sheet that when installing the spacer, be sure to check that the oil filler cap collar is not stuck between the spacer and the intake - seems to be a common issue, and I ran into the same thing. 2) Provide screws for all the holes so they all match, or source screws that will appear like the oem screws for consistency. But otherwise, a fantastic product!

Great product, came with everything I needed and even plenty of spares. Installing this gave the mid to high end rpm a Much lower tone at WOT. The Z Tube gave the low end the same effect but struggled to flow air without the spacer. Overall very satisfied and worth every penny

This thing is mint. It’s 9/10 doctors approved the 10th doc has a genny (he’s just salty because the other 9 who drive VQ cars always beats him after they added the spacer) it even helps on gas mileage. NOTE : I am not liable if ur VQ car doesn’t beat a genny after the plenum spacer. :)

Easy install and adds a noticeable punch around 3k rpm. Only issue I had was I had to use 2 of the longer spare bolts that came with the kit instead of using the stock bolts(per insructions) as they were too short and didnt hold the upper plenum down.

did not really notice a acceleration improvement, But averaged 24 MPG on a road trip. Have a 2004 FX35AWD, factory specs says 20MPG. AT 4 MPG pay for itself real soon.

Bought and installed the intake spacer on my First Gen FX35,driving it normal you can’t tell much off a difference but after 3000 rpm she definitively pulls much harder then before! My intake air temps are about 5-10 degrees cooler also.Great products at a great price.Awesome team. Thanks Z1!

Spacer kit came with its proper tools and made installment simple following the directions it came with. The only thing is my OEM strut bar did not fit well with the few washers it gave me. Be prepared to have M10 30mm longer bolts and Thicker washers just in case, because the Strut bar is considered a separate fix. Other than that, the spacer works great and gainned lot more mid-torque. 04 350z

This is one of the most common modifications for the VQ35DE motor. I installed it on my 350z and I noticed a deeper engine sound at higher rpms especially at full throttle. I can also tell there is an increase in acceleration response above 3000 rpm. This was a simple install to do except adjusting the strut bar with the washers. Overall, I'm pleased with the results.

If you are reading all these reviews, it probably means you are on the fence about clicking the add to cart button... just go ahead and click it! I was also on the fence about ordering this for a very long time. I finally bit the bullet and ordered it... I should have done this YEARS ago. This is the best $170 dollars I have ever spent on my Z! You know how there's those mods you do where you think you maybe can feel a difference but you aren't sure? Well this isn't one... I instantly knew this made a huge difference in mid and top end HP and torque. It definitely feels much stronger. I'm not going to say it's some crazy power gain, but it is definitely noticeable. Just make sure you do the ECU reset. Also when installing be sure you don't pinch the rubber seal around the oil cap between the plenum and spacer, or you will have issues! This is a very simple and extremely satisfying mod to do for a small amount of cash. Once again, a other great product from Z1 motorsports that has put a big smile on my face!

So here's my take on this plenum spacers. You can definitely feel and hear the difference. Much more responsive. Expect to be surprised when you punch it after installation. And your car will growl after as well. I was really pleased. Except in the instructions it says to use some of your old bolt for hole #8 #9 #14 and #15. Which did not reach at all way too short. That resulted in a horrible vacuum leak and horrible idle problems. So I had to improvise. Order a plenum spacer fastener kit, same issue and ended up usining some of the longer bolts that came with this kit te replace those and problem fixed. And I see the TRUE potential and I love it. I suggest you get a buddy to help its hard hold up the plenum and align the spacer and 2 gaskets correctly.

Unlike the fitment problem I had with the bolt on wheel spacers, the plenum spacer install went smoothly and the fitment was perfect. Took about an hour to remove and reinstall, and the another half hour to install the pop charger. That went smooth as well, everything fit according to plan.

The Z1 plenum spacer is a great addition to any Z. Very easy install and can be completed with basic hand tools (sockets, and ratchet ect.). My tip would be to remember to adjust the legnth of the stock strut tower brace prior to re-installation. Even with using the supplied spacers the bar needs slight adjustment for engine clearence. End result is a slightly deeper more agressive exhaust note. My 05' touring AT felt quicker when accelerating past 3k rpm's. Great product, easy install, would definitly buy again!

The Z1 plenum spacer is a great addition for anyone looking to do a quick simple modification to thier Z. Installation was easy and straight forward, able to complete with basic hand tools (ratchet and sockets ect). Most difficult part is re-installing the stock strut tower brace. My tip would be to remember to adjust the legnth of the strut bar prior to re-installing, you\'ll need to adjust for engine clearence even with addition of the supplied spacers. The end result is a stealthy mod that sounds slightly more deep and agressive. Used on my 05\' touring auto - feels more responsive and will definitly notice quicker acceleration past 3k rpm\'s. Great product and a great price! Would definitly buy again.
