The Airaid Intake System took less than 10 minutes to install. Instruction were clear and all assembly items lined up perfectly. Throttle response seems much quicker. Noise level increase is negligible. Full throttle sound is more 'throaty'. Will monitor the gas mileage variation. Airaid Throttle body spacer is next on the list.

great air cleaners!

didnt really notice any HP gain but it does sound great. it has a nice growl with stock exhaust. 2014 ford raptor. i think the whole HP gain is a gimmick with all the computerized engines. very easy installation! better than stock for sure!

Seems to give the truck a little better pickup but the sound is not as good as I expected. I put CAI on all me vehicles and this is the first time it did not add a deep sound.

I was very surprised at the MPG increase with the Airaid Intake System. The overall MPG for my truck is now 21.5. Before installing the Airaid it was 21. The last 6000 miles has averaged 22 MPG and the last 2000 miles (after installation)has averaged 24.1 MPG. I wanted to drive over a 1000 miles before I reported the results. My truck is a F-150 3.5 Ecoboost 4x4 super crew cab, 6.5' bed and 3.73 locking axle. Driving includes highway, town and mountain roads in Colorado.

works great

I upgraded my intake with this airaid filter system. The instruction to install the system were great! The quality of the intake system is top of the line. It made about three miles per gallon difference in my fuel mileage and I cannot think of anything better to say about a product other than it works as advertised.

awesome

This is a very easy bolt on part. in addition to the Poweraid spacer my 2011 3.7l L v-6 F-150 when driven normally has gained 2 miles per gallon. when driven hard the power seems and acceleration seem to have increased noticeably. This filter gives the engine a great sound that turns heads. Performance exhaust is next.
