Even for a "non car guy," this was extremely easy to prepare and install, with the exception of seating the assembly within the box into the intake manifold connector hole; that was a bit tight. My truck's idle speed dropped about 100rpm, and on speed control, it is downshifting one fewer gear on specific hills I take on a daily basis, so it is a great benefit for a very economical price.
The cover was broken when I got it so I had to inprobie in one corner!
Road trip did show better gas mileage.
I can not tell a difference in power but it definitely shifts faster and smoother.
Easy to install, no significant issues. Looks good, sounds a little louder than rock but not annoying.
Very good instructions just need to a note in : if you purchase the pre-filter to install it before putting the filter in the box. A real pain afterwards. Everything fits nice and snug. Anyone can install it. Only have 20 miles on it and waiting to see any improvement on mpg. Sounds great
