Perrin Cold-Air Intake System 08+ STi/WRX

Increase horsepower and style under your hood with a PERRIN Cold air intake system. This new 08 Intake was designed from the beginning to be a cold air intake. This provides much better more consistent HP and better drivability 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.

In designing our research team found that the 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. This new MAF sensor is much more sensitive and our intake does throw off the MAF curve resulting in the car running differently than normal

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

You will see consistent gains in horsepower, throttle response and fuel economy. Also available in a cold air version for those wishing to extract every last bit of power from an intake system. Each Intake System include colorful and powdercoated aluminum and silicone tubing, a PERRIN PerformanceTM foam air filter, MAF sensor housing and mounting hardware.
