Cabin air filter

Reviewed By Doug G (WESTMINSTER, CA) Reviewed for a 2013 Kia Optima —1/2/2018 9:57 PM

Easy to install, shouldn't take you more than 5 minutes. Love the fact that it is reusable and cleanable

Much needed for cold air intakes

Reviewed By Kevin T (Fremont, CA) Reviewed for a 2006 Honda Civic —2/12/2018 8:15 PM

Installed this on my injen cold air intake for my civic. My car is lowered and does not have the protective splash guards anymore due to it coming off. This saved my car from sucking in water through the intake during the short rainy season of California. Definitely worth the buy.
