"I haven't worked on a car for many years. I found the instructions to be pretty small so enlarged them on a copier and found the detail to be very acceptable. Had no problem except installing the piece on the mount that houses the actual filter was a real challenge. Separate pieces would have made it much easier. Other than that I spent one easy hour installing the kit. Vehicle has more pick up and is much more responsive than with stock filter. Glad I made the purchase." —Charles S from Fort Worth, TX bought a K&N 77 Series Metal Intake Kit for a 2005 BMW Z4.
