Ok so ive got a cone filter on and my engine bay is always red hot so basically ive got red hot air going into my cone filter.... Is it better than a standard filter? Should I put a standard filter on? Why do people drill standard filters? How do you drill a standard filter? Just a few questions really to help me decide what is best... Also is a series 1 standard air filter the same as a series 2?? Thanks for any input......
