Perrin Cold Air Intake (18-21 STI)

Increase horsepower and style under your hood. PERRIN Intake Systems use proper MAF alignment and tubing size, both of which are crucial to maintain proper air-fuel ratios and prevent check engine lights that plague competitors.

No Tuning Required
Increase horsepower and torque without ECU recalibration or tune! This part is designed to work safely on your vehicle without any tuning required! With our rigorous testing, you can be assured of proper operation and power gains! However, more power can be gained with proper ECU tuning! Be sure to confirm any tune or recalibration you add is specific for ALL modifications that have been added to the vehicle.

Precision Construction
Our 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.

Filter Tech
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 prevent damage from debris and is ideal for dusty and rough driving conditions.

Air Straightener
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.

Sound
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.

Finish
Powder-coated for protection from the elements, the glossy neon yellow or hyper teal will accent your show car while the classic textured red and black finish will look awesome for years to come. Our Intake is available in black, red, neon yellow, or hyper teal powder coating.
