The K&N 57-5005 FIPK air intake system replaces the restrictive factory air filter and air box in some Mazda RX-7 models. K&N intakes are designed to dramatically reduce intake restriction and improve air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-5005 air intake comes with a chrome topped K&N high-flow air filter that installs onto the factory mass air sensor within the previous air box space. Air is directed through the air filter into the engine’s throttle body for a guaranteed power gain. The oversized, oval cone-shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes requiring commonly available tools to do the job. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Product Reviews


  I have a fairly fresh rebuilt 13B with a full after market exhaust header to tail pipe. When I installed this kit it really did make a difference. Especially in the low-mid range. With all orig. equipment, RX-7's don't have much torque or H.P. below 3,000 rpm's. That is where this helped the most. Example: on I-5 in 5th gear at 65mph if you floor it, the response was very slow with all orig. equip. After installing this kit, I can feel it respond, in 5th gear at 65! And when I took it to an autocross that I do monthly, it made a diff because you start standing still. And really need throttle response in that type of competition. I'm sure it makes a diff with an all stock car, but with the full exhaust it REALLY changed things! As a side note, I went ahead and changed my O2 sensor because it was orig. and was over 20 yrs old,,, that helped this kit get the most perf.
