Perrin Cold Air Intake (08-14 WRX, 08-17 STI)
PERRIN Intake systems use proper MAF alignment and plumbing size, both of which are crucial to maintaining proper air fuel ratios and preventing check engine lights that plague competitors. Add 15-30 WHP to your car. Actual horsepower values will vary depending on other installed hardware, tunes, and overall condition of your vehicle.
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 alignment of MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management. Powder coated for protection against the elements, the textured finish will look awesome for years to come. The PERRIN WRX/STI Cold Air Intake is available in black or red wrinkle powder coating. 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 airflow straightener improves MAF readings by forcing incoming airflow into a uniform profile. Smooth and predictable airflow is the key to good, consistent MAF sensor readings for reliable horsepower gains.
