Product Description
The Process West Cold Air Intake is perfect for gaining more power from your EJ Subaru, not to mention the sound!
The Cold Air Intake Kit is designed to replace the factory air intake and allow for a less restrictive airflow.
Made of lightweight CNC mandrel bent aluminium tubing with an airflow meter mount machined on which enables you to utilise the standard airflow meter.
Having designed and manufactured the best Cold Air Kit on the market for the 2015 car, Process West have gone one step further with this kit by increasing the inlet track diameter from 72mm to 76mm allowing a greater volume of air to reach the turbo. Caution!….remember however, you will need to re-scale the mass air flow meter prior to running.
Process West also provide a K&N high flow air filter with all the Cold Air Intake Systems they sell. Finished off with a flawless Black coating for a factory look.
