Z1 350Z / G35 Cold Air Intake Kit - VQ35HR - CARB LEGAL

starstarstarstarstar_half 4.8/5 - (31 Reviews)
Fits models: 350Z / G35...

Product Description

The Z1 Motorsports 350Z / G35 Cold Air Intake Kit for dual throttle body cars provides improved flow and a cooler denser air charge resulting in greater combustion efficiency and more power. Significant gains in power and response have been proven with this torture tested intake.

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

Carb Legal EO: D-849

Features

Constructed of a mandrel bent 6061 aluminum tubing, TIG welded, polished, and features an integrated MAF housing for greater airflow, weight reduction, streamlined aesthetics, and overall product performance. This kit was designed to allow customers to install this intake without the need for immediate tuning, although a dyno tune is recommended to get the most out of your VQ. The improved density and flow rates help iinvigorate the output and even sound of your VQ35HR engine with a deeper growl in low RPMs and aggressive tone in higher RPMs.

Cold-Air InnovationZ1 Velocity Stack

The new intake uses race-proven technology by including two specially designed large-media air filters with integrated velocity stacks for increased air flow. A velocity stack is designed to maximize and optimize airflow by allowing air to gently enter the intake piping through an unobstructed rounded taper (similar to a trumpet horn.) This results in less intake turbulence and increased air velocity, allowing your intake system to work at it's maximum potential!  

Aesthetically Pleasing

While the primary focus in aftermarket intakes may be enhanced performance, our focus was to provide a product that performed tremendously while providing a show quality finish and appearance. Available in two finishes, black and polished aluminum with your choice in Red, Black, or Blue Silicone Couplers. The intake also features MAF bosses that have been relocated to the bottom side of the intake piping for a stealth-like appearance.

Performance

While every cars result may differ depending on mods and tune, Z1 Motorsports was able to achieve an increased 11whp and additional 10lb-ft of torque with peak gains of 16whp and 12lb-ft of torque at the peak of the power band in-house on a car previously equipped with just a Full Tomei Expreme Exhaust! No re-tune was performed to achieve these results! You can expect even greater results when re-tune is performed.

Upgraded Velocity Stacks

Z1 also offers an oversized velocity stack upgrade helping push the potential of these intakes EVEN FURTHER! This upgrade can be purchased HERE and adds larger filters and velocity stacks which allow for better airflow producing even more power gains than the intakes alone. This upgrade has produced 5+ RWHP consistently on several Z's with dyno tune. As you can see from the dyno graph below, this upgrade produces more horsepower and torque across the entire RPM range.

Questions our customers have asked

Do you guys sell one of these for a vq35de?
We do have a very nice cold air intake available here: (Link) Regards, The Z1 Team
I'm trying to add a little horsepower to my 2006 g35 coupe I was wondering Would this intake fit my 2006 g35 coupe or would it be something different? And what are a coupe more things I can get to add horsepower?
You will need something for the DE engine with only one throttle body. Like the Z1 intake package (Link) or the AEM (Link) or the Injen (Link)
What size is the tube/pipe ? 2.5"? 3"?
2.5"
Hey by any chance is this intake carb legal? Out here in CA the police tend to be a little bit anal about modified cars. If it came carb legal that would help a lot.
This is now CARB legal!
Is a tune needed after install? Planning on doing intakes this year and tune next year.
Josh, A tune is not required after installing Z1 intakes. Regards, Z1 Team

So far so good. The cold air intakes have been a great purchase. The install was fairly easy after removing the bumper. If you plan to tune your car, I would get the 3-inch intakes instead of the 2.5. As I will upgrade soon after my tune.

Easy install with slight changes to horn location on the 350z VQHR. Car feels 10x more responsive compared to my old Stillen gen 2 intakes and definitely a notable increase to the butt dyno.

Upgraded to these intakes from the Takeda short ram intakes. While I did enjoy the Takedas, Z1's Cold Air Intakes made a noticeable difference reducing heat-soak and increasing mid range power in the HR. Install of the intakes was straight forward. Really easy if you're familiar using basic tools. I did have an initial issue connecting the air filter pipe to the L shaped silicone coupler. The pipe is just marginally smaller than the coupler, so it took some muscle to connect the parts. Otherwise, 10/10 fitment and install. Thanks again Z1

I didnt know what expect putting these on with no tune yet and let me say i do truly feel a difference it sounds like the engine breathing better and its more responsive and feels good all round and install was easy for the most part just was a little annoying getting things to fit perfectly lined up so itll all fit perfectly but otherwise it was alittle over 2 hour install

It’s okay. Id recommend going with the 3inch intake personally. Install was pretty easy, figment is key. I got my front bumper back on but wasn’t able to fit the impact absorber on with the intake. Drivers side intake resonator (or whatever it’s called) also needed some adjustments.

Contemplated what intakes I should get for my hr for literally like an entire year. Finally decided on these ones after seeing jimmy oaks video on them. I’ve had them installed on my z for just a few days now but so far they are great! Added a little bit of pep and throttle response for sure!! And definitely gave my z a better sounding tone. And looks a heck of a lot better. Super easy install I’d say it took me about 1 hour at most

Z1 shipping has never failed me, they are honestly faster than Amazon. I ordered this product from them because I needed intakes as fast as possible. The intakes came perfectly packaged and nothing was damaged, I ordered black and red to match my car. After installing them I wouldn’t recommend you buying them if you have a KBD nismo bumper. The intakes did not fit with my bumper, after some hard thinking I had to bend the intakes back around my radiator and relocate my horns for it too work. Z1 Advertises these intakes as not needing tune, but if you are already heavily modified like I was, with a full exhaust and long tube headers you will most Definitely need a tune. After installing them on my car idle was horrible, my car ran rich, and my car Through codes of misfires in all cylinders. After my tune a week later the car was perfectly fine.

Took 3 hrs to install but what a difference it made. Feel more power. Definitely happy with the purchase. Recommend checking out the directions for horn relocation, baffle removal, and cutting tube on driver side.

Great product! Fast shipping. Ordered Monday night and was on my door step Thursday morning. If you’re think about going with a cheaper intake, DONT. This is perfect, I haven’t gotten my tune yet b/c more mods on the way, but you can definitely notice a big difference in acceleration and throttle response, feels like a whole different car even without the tune. Best thing is my ECU like them too, no CEL. Overall fantastic product especially considering i dont usually write these reviews. Only thing i had trouble with is where they tell you to trim the baffle, even after trimming, i couldn’t get it to line up without kinking the hose, i came close to cutting the hose to make it shorter but alll in all i eventually worked everything together getting it to work and it looks amazing sounds amazing and runs amazing. I’d definitely recommend, just like everyone else said though, get some silicone lube. Easy to get on, a nightmare to get off.. good job Z1

Bought this kit for a Saturday morning install and it was perfect. The modification made to the driver side pcv baffle is no problem. I recommend for anyone to buy this kit as it is a noticeable difference in throttle response and low end acceleration. Next for me is test pipes and their modified intake plenum + spacer and a rev up tune. Good luck everyone.

Super easy install and combined with test pipes, made 306whp and 281 torque on the dyno. Best bang for your buck in my opinion. If you have an HR, you need this, test pipes, exhaust, and a full tune with ARC and you are good to go pushing the 300 whp mark. quality of the parts is amazing. The only thing I would advise is to spray the couplers with silicone to make them slide on the pipes super easy.
