The system was very easy to install with all the parts not only fit perfectly, but were all in the package. These days that is great paying to detail in packaging and also in the design of the parts. Works great and looks great! Lonnie B.

Remarkable. My 2006 Expedition has 108,000 miles on it and has a K &N cold air intake. Autoanything shipped the throttle body spacer out super fast. It literally took 30 minutes to install. As soon as I stepped on the gas for the first time I was like wow! The extra power was amazing. Now all I need to get is an after market exhaust. The only problem I have... I don't hear any whistle!
