INTAKE COLD AIR WRX, STI, FORESTER

Increase horsepower and style under your hood with a PERRIN Cold air intake system. This new 2008+ Intake was designed from the beginning to be a cold air intake. This provides much better more consistent HP and better driveability in all conditions. We also found that the stock intake does get heat soaked and causes a loss in power due to the high temps the sensor sees. Proper MAF alignment and plumbing size are crucial to maintain proper air fuel ratios and prevent nasty check engine lights and cause the car to run dangerously lean. While this is very true we have found that the new 08 MAF sensor is much different that MAF sensors in the past. With this said, it is very important to note that our intake is OK to bolt onto a stock tuned ECU vehicle. It is NOT OK to bolt onto a car with a custom tuned ECU vehicle. Because the intake does change how the car runs on a tuned map, we do offer Specific PERRIN custom tuned maps for our intake. If you are already a customer of the PERRIN Custom tuned Maps, these will be provided for free if you purchased our intake. If you are not a customer of the PERRIN Map program, you can simply order one of our custom maps through our website LOCATED HERE The below run is done with our existing Stage 2 tune in place. The runshowing the gain in HP has the same timing curve and Air Fuel ratio asthe other run. This proves the intake makes HP by being freer flowingnot by changing the fuel or timing or boost for that matter. Increase horsepower and style under your hood with a PERRIN Cold air intake system.
