Great service from a great company!

I’ve always had fantastic service working with ETS. This is the same exact filter you get when buying the whole CAI bundle. I needed a replacement after mine got damaged, so this was a great option!

Always a pleasure to purchase from ETS

My guys came through big time with my new filter and box. Given all the craziness going on in the world 3 days for shipping was top notch service in my book. Thanks again!

Ask a Question
  • What is the k&n part number for this replacement air filter for a 19 wrx? DP-3603 isn’t populating anywhere. Can I only get the filter from this site?

    We use our own specific filter. The Generic K&N filter that works in its place is an RU-2800.

  • How often should the filter be replaced?

    This is a cleanable and oiled filter. The link below will walk you through the process. With maintenance they should last the entire life of the car. 

  • Are these pre oiled or dry?

    These are preoiled filters manufactured by K&N for us.

  • Does this filter work for the turbo intake system

    Yes, the turbo kit and the stock turbo intake use the same filter.
