2006 Toyota 4Runner Sport V8
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!
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.
