Description
Better Flow for More Power. Improve the power and performance of your 2012-2018 3.6L JK Wrangler with a Deegan 38 Cold Air Intake. By replacing your Wrangler's restrictive factory intake with a high flow filter assembly, you will see and feel a noticeable increase in rear wheel horsepower and torque. This Deegan 38 Intake not only improves airflow for an increase in power, but it will also add an aggressive appearance to the engine bay with its textured black steel intake tube.
No Tune Required. Deegan 38 engineered its Cold Air Intake to improve the performance of your V6 Wrangler without the need of reprogramming your computer. By utilizing flow dynamics, this Intake will increase power using the original factory tune. Even though a re-tune is not required for operation, ExtremeTerrain recommends a custom tune to reprogram the vehicle's computer (ECU) to get the best possible performance from this Cold Air Intake.
Reusable Air Filter. The included high flow air filter effectively filters out power robbing particles with its multi-layer design. The specially-treated media creates a sticky surface to capture microscopic contaminants before they can enter your engine and do harm. Seeing that the filter is reusable, there is no need to buy a new filter every few thousand miles. You can just clean the filter, re-oil it, and reinstall - saving yourself money in the long haul.
Simple Bolt-on Installation. Deegan 38 designed its Cold Air Intake kit to be a direct bolt-on replacement. With no special tools or extra modifications required, installation can be completed in under an hour. All parts and detailed instructions are included.
Application. This Deegan 38 Cold Air Intake; Textured Black is designed to fit 2012-2018 Jeep Wrangler JK models equipped with the 3.6L V6 engine.
