I switch to k&n air filter after driving my friends ( 01 Mercedes S500) I notices the approve acceleration. Which my car didn't have with non- K&N air products. Once I switch I notice the improve acceration and fuel efficiency. I install K&N in my 99 GMC conversation van (explorer SE). Got great results.
