The PERRIN intake is a high-quality aftermarket intake system designed to increase horsepower and torque without the need for ECU recalibration or tuning. Here are the key features of the PERRIN intake:

1. No Tuning Required: The PERRIN intake is designed to work safely on your vehicle without requiring any ECU recalibration or tuning. With rigorous testing, you can be assured of proper operation and power gains. However, it's important to note that while the intake provides increased power, even more power gains can be achieved with proper ECU tuning. If you choose to add a tune, make sure it's specific for all modifications on your vehicle.

2. Precision Construction: The intake is constructed from aluminum tubing, which is precisely CNC mandrel bent for consistent and perfect fitting parts. The MAF sensor bung is also CNC machined to ensure a perfect fit and alignment of the MAF sensor to the intake. This is crucial for maintaining proper air-fuel ratios and ECU engine management.

3. Dryflow Filters: The PERRIN intake uses Dryflow filters, which provide the same level of protection as oiled filters but require less maintenance and have no risk of over-oiling. The rigid screen inside and around the filter media helps prevent damage from debris, making it ideal for dusty and rough driving conditions.

4. Airflow Straightener: The intake includes an airflow straightener, which improves MAF readings by forcing incoming airflow into a uniform profile. This results in smooth and predictable airflow, leading to reliable horsepower gains.

5. Sound: During normal driving, the PERRIN intake sounds relatively stock. However, under load, it comes to life, unlocking the sound of your turbo flat-4 engine. Once installed, the sound of your blowoff valve will be much more prominent, adding to the overall modified experience.
