Originally posted by Aussie SVT: I just bought a 3.5"ID x 5" Big Mouth filter from www.intenseperformance.com It has a HUGE inlet trumpet that accelerates the air more smoothly than the normal S&B Powerstack filter that KKM sells. I mated that up with a BAT MAF adapter, and I have the BAT pipe too. I have yet to install it as the car is at the dealer getting the tranny rebuilt, but I hope to have it back today and then I will install it. I am going to make a new heat shield too, and with my hood scoop I should be getting high flowing cold air to the engine. I will posts pics when it is all done.
