Increase horsepower and style under your hood. PERRIN Performance intake systems use proper MAF alignment and plumbing size, both of which are crucial to maintain proper air fuel ratios and prevent check engine lights that plague competitors.
PERRIN intakes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfectly fitting parts. Our MAF sensor bung is CNC machined for perfect fit and proper alignment of MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management.
The PERRIN Cold Air Intake for the WRX comes with a heat shield to redirect hot engine air away from the intake to allow for near ambient air intake temperatures.
Dryflow filters provide the same level of protection as an oiled filter, but require less maintenance, are less of a mess, and have no risk of over-oiling. The rigid screen inside and around the filter media helps in preventing damage from debris and are ideal for dusty and rough driving conditions.
The OEM MAF sensor wiring harness is too short to work with the PERRIN Cold Air Intake. Provided with each kit is a MAF sensor extension. This extension comes with OEM plug ends to relocate the MAF sensor with no compatibility issues.
During normal driving, the PERRIN intake sounds relatively stock. However, under load it really comes to life, unlocking the sound of your turbo flat-4. Once installed, the sound of your blowoff valve will be much more prominent, demanding attention and alerting people that your car is undeniably modified.
