The 69-8004TTK features a aluminum intake tube in powder coated black and a K&N carbon fiber top filter (RP-5113). Our lifetime washable and reusable air filter is isolated by a steel heat shield to provide fresh air to the engine.

The horsepower gain is also aided by the radius adaptor’s design as it smoothly takes the 5 inch flange of the air filter and connects it with the air intake tube. The air intake tube has a CNC precision machined billet mass air adaptor.

The high-flow technology invented by K&N provides the best balance of airflow and filtration. Designed to be installed with simple hand tools in 90 minutes or less, our K&N air intake systems are backed by the K&N Million Mile Limited Warranty.

The 69-8004TTK air intake system fits the following Subaru Imprezas:
2014 Subaru Impreza WRX 2.5L
2013 Subaru Impreza WRX 2.5L
