k&n 57 review
The system was very easy to install and took me less than 30 minutes. So far I have noticed a very slight increase in fuel economy and acceleration. I am hopefull adding a performance exhaust will increase my power additionally and give me the needed boost when pulling my travel trailer. The k&n system is an expenditure I would recommend to everyone. A vert good value.

I go the K&N 63 series and everything went great with the exception of a few things. One of the nut and bolt that attaches the the Frame was way to short to fit all the washers and the Spacer. The other major problem was the Recalculation hose which you have to cut to fit. The port which accepts the recirc tube is not lined up with where the hose comes out of the engine cover which makes you kink the hose 90 degrees inorder to get it on the CAI Tube. this should be a factory 90 or a pre bent.
Impressive!! Really woke up my 2.5 liter!!
Installation was a breeze for me, but I was a mechanic by trade for many years. The only thing that I didn't use was the Alan screws supplied for the mass air sensor, the OE screws had washers built on them " a flat and a lock not removable" the supplied screws didn't, and the alan wrench hole was not perfect, wrench would not fit all the way in! Just used the OE screws! Not sure about gas mileage, just installed. Can definitely tell there is a increase in horsepower, i love the new sound????
