Ok before you guys says Use search, ive done that.

but what im wondering is , after how many miles do i change my Stock engine filter for my Coupe. Ive dusted it out 2 times but i think its time for a new one.

and what is a good brand and how much should i pay for a decent one ?

 

Change it every 30k.

 

wow , im past that by 4 thousand miles thankyou
