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.  


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 invigorate 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 air flow by allowing air to gently enter the intake piping through an un-obstructed 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.


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.

Response: 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"?

Response: 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.

Response: Sorry Keon, the Z1 intakes are not CARB legal for CA. Stillen Gen 3 intakes are however CARB legal (CARB E.O. #D-436-16) Link below. (Link)

Is a tune needed after install? Planning on doing intakes this year and tune next year.

Response: Josh, A tune is not required after installing Z1 intakes. Regards, Z1 Team
