I was looking for better gas mileage,And got alot more!The truck has a noticeable power increase,I was getting 18.5 mpg and now it's 22-24 mpg.That alone was worth it.It also has a sweet sound when you lay in to the throttle and a nice whistle when cruising! Totally worth the price.I highly recommend.

Good Product, but pieces missing in the hardware kit!

This is a straight forward kit to install, but the throttle body spacer kit had an extention bar missing. I used a metal L bracket(used for supporting corners in wood working) and fashioned an extention bar from that. Also, the breather tube from the right valve cover has to be extended to properly fit in the intake tube. I used a piece of 5/8" heater hose to fashion it. This info was not in the installation instructions. Helps to have some mechanical ability!

For those that is buying for the Ranger a little bit of warning DO NOT GO THROUGH CAR WASHES because water can seep into the air box other than that it is the best intake system I have ever bought, very easy to install. Power increase is amazing and the sound is insane, shipping was great ordered on Monday recieved it on Thurseday and got a speeding ticket on Sunday so pick and choose where you test drive, good luck.

Installation went fairly well, had to reverse (2) of the bolts to get filter to seat properly into baffle. Performance has improved a little, waiting to see if gas mileage is up.

Great buy!!!

I love my Airaid Intake system! It was simple to install, I noticed a moderate gain in power and a considerable gain in my fuel economy. Definitly a great buy for the money.
