Z1 Replacement Air Filter for Z1 Cold Air Intakes used on both VQ35HR and VQ37VHR equipped vehicles.

This unique air filter was designed in house exclusivly for use on the Z1 Motorsports Cold Air Intake on HR/VHR equipped cars. Like any air filter, Z1 filters are subject to damage from light impact, minor collisions, and wear throughout the life of the vehicle. These filters are specially designed to fit the stock crashbar and core support and because of these tight clearences cannot be substituted, therefore they are now available seperatly. 

This specially designed filters use race proven technology by integrating velocity stacks along with a high flow cotton media for proper 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!
