3.4right? Back in the day i just took a spectra 90degree elbow and put on a k&n air filter.
but honestly don't waste your money on this engine, trust me i know and wasted a ton. In your other posts you mention you are saving for a ws6 so do that. skip the headers, intake, and anything else you might want - keep it clean and looking nice and save for something with real balls. The below video was my old 3.4 with headers, high flow cat, comps cam 260H and an open cutout. sounded ehh at idle and **** with the pedal on the floor. trust me just save your money.
