Perrin Cold Air Intake
Precision Construction
Perrin's intakes are construced from aluminum tubing, which is precision CNC mandrel bent for consistent and perfectly fitting parts. Perrin's 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 maintenenace, 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.
Air Straightener
The airflow straightener improves MAF readings by forcing incoming air flow into a uniform profile. Smooth and predictable airflow is the key to good, consistent MAF sensor readings for reliable horsepower gains.
During normal driving, the PERRIN intake sounds relatively stock. However, under load it really comes to life, unlocking the sound of yoru turb flat-4. Once installed, the sound of your blowoff valve will be much more prominent, demangind attention and alerting people that yoru car is undeniably modified.
