K&N 2018 Subaru WRX STI H4-2.5L F/I Typhoon Performance Intake

Gain a guaranteed increase in horsepower and torque with a K&N cold air intake system featuring a mandrel-bent aluminum intake tube. Each system is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical filter design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield or air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California. See the product specifications for CARB status on each part for a specific vehicle.
