Description
Effective CAI for An Engine Upgrade. Giving your truck a more athletic, deep-breathing engine performance, the K&N Series 77 High Flow Performance Cold Air Intake does double duty as an engine “dress-up” part with its gleaming polished intake tube. Since it’s made of aluminum, that tube won’t get dimmed by rust or corrosion, either, but with a little care will continue to offer some shining metallic “eye candy” under the hood. Not just another pretty face, though, the Series 77 CAI delivers…

Great product and complete kit. Definitely notice the acceleration difference and sounds awsome. Recommend to all my buddies that have the 5.4, worth every penny!!

As we all know K&N has great quality products and I will always recommend it. In this case I’m not sure what happened but the 90d silicon elbow had two separate diameters and one side was about an inch in diameter too big, so I had to go find my own part for it. And no the throttle body is not after market. But we sorted things out here with American trucks and I’m pretty happy even tho I still can’t use the truck until I get my new elbow delivered.

Very great product and only took about an hour to install, K&N is top of the line when it comes to Cold air intakes so make the right choice and pick this one up asap!

The CAI took about 90 minutes to install along with an Airaid throttle spacer, and Jet Mass Air Flow Sensor. A great improvement to the look of the 5.4 Triton V8. There didn’t seem to be a difference at an idle, but once on the road, there was a good deal of improvement in acceleration and sound. Then on the highway is where the improvement in performance and gas mileage really stood out. There was an improvement in acceleration lag, still there, but better. Acceleration was vastly improved, The sound was throaty and turbo-like..If the gas mileage indicator is accurate it went from 12 and 13 to 15 and 16 miles per gallon. I am very satisfied so far. A great and fun improvement in performance for my 2007 Ford F=150 Harley Davidson Edition!! I look forward to my next mod.
