The Z1 Long Tube Cold Air Intakes for 2009-2015 Infiniti G37 and 2009-2020 Nissan 370Z are engineered to fix the biggest flaw in the VQ37VHR platform which is heat soak and restrictive factory airboxes that choke your engine with hot, turbulent air from the engine bay, and unlike cheap eBay short rams that just suck in engine heat and throw MAF codes, these true long tube intakes relocate your filters down into the front bumper cavity where they pull in dense, ambient temperature air directly from outside the vehicle for real power gains you can actually feel on the street and on the dyno with proven increases of up to 18whp and 14wtq on stock cars and even more with a tune, featuring 3 inch mandrel bent aluminum piping with smooth radius bends to maximize airflow velocity, high quality silicone couplers and T-bolt clamps for leak free connections that won’t pop off under boost or hard driving, and massive 6 inch dual cone air filters with inverted tops that provide huge surface area for unrestricted flow while still offering excellent filtration to protect your motor, the kit includes everything needed for a bolt on install including CNC machined MAF housings with integrated velocity stacks to prevent turbulence and keep fuel trims happy so you won’t get a CEL, detailed instructions, and all hardware, and they’re available in polished or wrinkle black finishes to match your engine bay aesthetic, designed and tested specifically for the VQ37VHR to improve throttle response, induction sound, and mid to top end power without sacrificing low end torque, these intakes are the gold standard for NA VQ builds and a must have supporting mod for anyone running headers, exhaust, or a tune because you can’t make power if your engine can’t breathe, and Z1 backs them with real R&D, real dyno data, and real support from a team that actually drives and builds these cars so you know you’re not getting some universal garbage that’ll leave you chasing issues.
