Z1 M-Spec 350Z Cold Air Intake Kit STREET Version - CARB LEGAL

starstarstarstarstar_half 4.8/5 - (42 Reviews)
Fits models: 350Z...

Product Description

Ignition of cooler oxygen results in a greater charge of energy during the engine combustion process. The Z1 Motorsports M-Spec 350Z Cold Air Intake Kit takes advantage of this scientific rule by relocating the engine air filter away from the hot engine bay and retrieves fresh, cold air from in front of the radiator, thus providing more power to your 2003-2006 350Z!

The M-Spec 350Z Cold Air Intake Kit is constructed of a mandrel bent aluminum tubing, TIG welded, polished, and features an integrated MAF housing for greater airflow, weight reduction, streamlined aesthetics, and overall product performance.

Invigorate the sound of your VQ35DE engine with the M-Spec Cold Air Intake Kit with a deep growl in low RPMs and aggressive tone in higher RPMs.

Included in the assembly are improved custom-molded silicone couplers, ABA style hose clamps, and a reusable Z1 air filter for durability. Unlike other cold air intakes, the M-Spec Cold Air Intake Kit mounts the Z1 air filter at the highest point possible to avoid water consumption and hydro-locking the engine in wet conditions.

This kit is will not bolt on to G35 coupes or sedans.

This STREET Version can be used on any 350Z with or without a tune.

We also offer the RACE Version of this intake which allows more air flow due to the larger diameter MAF cross section but does require a tune. Learn more about the Race Version HERE.

For more information please see our detailed INSTALLATION MANUAL.

Formerly produced by Momentum Performance.  The design and quality of this intake has not changed, simply the logo.

Only available through Z1 Motorsports.

For vehicles equipped with a NWP Engineering Throttle Body, Z1 offers a silicone coupler designed to work specifically with the Z1 M-Spec intakes that can be found HERE!

This intake is now CARB legal for road use in California. For information on replacement stickers, CLICK HERE.

Beautiful intake for my 2003 350z DE motor single intake. Install was quick and came with all the required pieces needed. Just don’t forget to hook up the vacuum hose under it when you put it on.

The fitment and quality are pretty good. Didn't have to fight anything to install it correctly. The problem I had was with all the metal shavings inside the tubes. I got the black version and noticed a significant amount of loose metal shavings and flakes. I used brake clean to clean them out and it ended up staining the black finish immediately. The intake works fine but it now looks permanently cheap.

2004- 350Z. This Cold Air intake fit my car very well. It took a bit of a struggle, but we were able to get it in without removing the strut bar. Because the finish was chrome on the unit, I suggest that you do not take off the foam packaging (except at the ends) during install of the long tube to prevent scratches to the finish. I also needed to order the larger silicone elbow at the throttle body as I replaced the stock TB with the larger 75mm throttle body. Noticing better throttle response and pick up in HP.

I love this intake. It has made a HUGE difference in the intake temps when connected to a 75mm throttle body (throttle body coolant line bypassed), and a Kinetix racing manifold.

Amazing product, the silicone joints are a bit stiff but use a little lube and it’s not a problem, however if you plan on putting a TFF bash bar on your z you will have clearance issues, to fix this use a 2 inch spacer on the bash bar and it will fit perfectly, other then that the intake noises are amazing and combined with a 75 mm throttle body and 5/16 plenum spacer your all set

I live in CA so was happy to find this CARB-approved version with stock diameter while also routing the CAI filter into the cool air stream beside the radiator. The stock MAF sensor is relocated to this new tube. Without a tune, there's not much increase in power, but I was more interested in helping the engine breathe than to see gains and I could feel an improvement at the track. I believe an even bigger restraint is the shallow upper intake so a spacer is in my next order. At some point I will be buying a 2nd ECU and tuning it for these bolt-ons while keeping the OEM stock for smog, but until then I can't go too crazy and screw up the AFR. This CAI is a great choice in that regard.

An interesting CAI for sure, glad I opted for this instead of the underhood CAI (which, granted, would have been easier to service). I do not like the difficulty in getting to the filter but once it's installed it should be good for a couple seasons without needing service so I'm ok. I installed mine without removing the front bumper cover but recommend doing that--and I will next time--because it's difficult to finagle the tubes in such cramped quarters. This CAI does not increase power much but what you WILL notice is throttle response which is what I wanted! Very snappy now compared to stock where the engine dropped revs more slowly. Now the engine responds to the pedal quickly. I was used to that with my Mustangs and glad to see the VQ respond in kind (and it's more rewarding than any Mustang sound). Damn I love this DE engine! I'm sure the RevUp and HE are similarly enjoyable. So bottom line: Buy this for the throttle response. Without a tune, there will be no power increase (the stock tune will adjust to the increased airflow). I wouldn't be surprised if it did make +10 hp because it feels as good as it sounds but that wasn't the goal.

Easy install. However, I had to flip my Z1 oil cooler in order for the fittings not to collide with the filter. My fittings now point downwards and I find it a bit dangerous if I hit anything. I have a Z speed undershroud but I still think it's not an ideal position. Maybe a review could be made if someone also installed both parts.

Puts a smile on my face every time I pop my hood. This holds memories for me because I didn't tighten the intake filter enough during installation and it fell off while driving so I had to buy another one. Lesson for when buying any parts, always double check every nut and bolt and in this case every clamp is nice and tight. Overall perfect product for what I was looking for.

Not a lot power gain but it’s a lot louder than stock and with a tune it’ll be even better 👍🏾. Overall Great intake system and definitely worth it in my opinion.

Install was very straight forward and quality was great. Just wasn’t an absolute perfect fit in the front core support. Not sure if RHD Z33’s are different than US but very small complaint still love the product.

Overall a great intake for the price. The fitment was a bit iffy and it presses up against the radiator quite a bit but I'm also not a professional and that might be user error. I can't speak for the intake sounds as I can't hear them above my exhaust but I'm sure they're there. As for installation you definitely want to remove the front bumper and crash bar as they are not hard to remove and it makes the install much easier.

I believe improvements could be made with This design I really like what they have going, but for the money it should be a little more precise and include labeled parts and instructions. putting it together with no instructions or labeled parts is quite complicated. The instruction video is makes it look simple but it’s not. The air filter was giving me a lot of trouble and the Mach up is a trial and error process.

I switched from a nismo cold air intake to this intake and i could not be more happy. i love the finish on the black intake pipe. THIS IS A MUST HAVE FOR YOUR 350Z !!!

Great intake and I love the placement. I have moved to this after owning a Nismo Cold Air Intake bought from Nissan. Did not like that one at all due to the placement by the wheel. In dry situations it worked well, but was hindered severely when it rained. This intake however is up high and in front of the radiator. Which allows for cold air still but not in a potential spot to suck in water from a puddle. Car exhaust has a deeper note now than with the Nismo intake and runs better too. I highly recommend this to anyone with a 350Z and wants a cold air intake.
