"The instructions were a somewhat weak and the pre-drilled housing holes were a little off. The MAF was tricky because the natural position to insert it was backwards. As a novice it took some trial & error to figure out what I did wrong. The Volant website should add some troubleshooting ideas to help out. Overall, I am very pleased with the look, sound and performance. Combined with my Borla exhaust, my power and sound upgrades are terrific!" —James K from State College, PA bought a Volant Cold Air Intakes for a 2004 BMW Z4, 4.7L V8.
