The Nissan 350Z cold air intakes offered here at PRO Import Tuners are one of the best ways to improve the performance and efficiency of your VQ35DE engine. These Nissan 350Z cold air intakes will allow your engine to breath in cold fresh air from outside of the hot engine bay. This colder more dense air charge mixed with the less restrictive pipe will allow you to bring in more oxygen molecules to the combustion chamber. This gives the Nissan 350Z cold air intake the ability to make much more power than the short ram style intake systems.
