The Pettit Racing Trak Pro Cold Air Intake was one of the first Induction systems offered for the RX7 back in 1992. Today as then, it is still the best system available. No other system even comes close in performance and/or simplicity of design.
Our V-duct system feeds both turbos cool outside air from the front nose opening (instead of robbing air from the intercooler or just taking in hot air from the engine compartment, both of which are common with most other systems.) Our unique EAM manifold helps maximize intake velocity and flow by eliminating turbulence in the main intake tract. This is accomplished by removing air pump & BOV intrusions from the main intake tract and connecting them to the EAM manifold with a separate filter. We supply two big K&N air filters; one per turbo and a 3rd smaller one for the EAM. Another simple design is the ICD Cover Kit; it provides a 30% gain to the stock intercooler's efficiency. This is accomplished by taking the cool air that was originally used to feed the stock air box (or in many cases it is just left open to be wasted) and redirects it into the Intercooler. Tthis further drops charge temperatures, providing a cooler, more dense charge. This basic design was adopted by Mazda and is standard on all '98 and later RX-7's.
Pettit has recently released an off road version of our Trak Pro Cold Air Kit. This is the ideal setup for modified RX-7's that have emissions and air pump removed, you still get all the benefits of our Trak Pro Cold Air Kit but save $100.
This induction is compatible with nearly all intercoolers that mount in the stock location and can be modified for use with virtually every imaginable setup. The complete kit bolts in the stock air box location in about an hour using basic hand tools, included are fully illustrated instructions and all necessary hardware.
