Ive recently installed a Air Filter, to my Astra 1.6 MK4 - But there hasnt been much change in sound, When I rev it I heard abit of the roar, But then it sound just standard like Ive got the normal Astra air filter box in.
I brought the Air filter off eBay Brand New. Ive had it in my Car for 1 Week and No Change in sound still.
It looks just like this one : - http://cgi.ebay.co.uk/VW-GOLF-MK2-MK...item3a5bb13efd
I dont know what it could be ?
I've looked online they say the Engine could be dirty should I do one of those Engine clean ?
Thanks for Reading
