To many issues with vendor and install. Purchased the product almost took a week to get the instructions are not very good and difficult to follow. Was not aware that both sensors on current intake system would no longer be used. Installed the unit per manufacture did not fit and could not mount to frame of truck. The intake performed well but could not use, and have had a nightmare trying to return. PROBLEMS all the way around. Could be that my truck was an older model, but would not do it.
