Bronco Easy & Quality Air Filter Improvement
Installed the product a few weeks ago and saw an improvement in gas mileage right away. It has changed over the weeks, but seeing about 1.5- 2 mpg improvement. Installation was extremely easy and just a few tools to complete. Fit easily and quality product.Definitely would recommend for the price.

Fuel efficiency improvement
Superior product for the price. I instantly noticed an improvement in both fuel efficiency and horsepower when compared to the other aftermarket engine air filter.

Perfect fit. Easy install
Excellent. Perfect fit. I wish it came with a label for noting date of install and milage.

Nice product: "Lifetime Filter"
Very happy that K&N resolved the issues they were having with this filter's fitment (Ford 2.7L). I actually contacted the K&N representative to ensure there weren't anymore issues with this filter's sloppy fit. Apparently, there were some serious Quality Control issues to remove MANY filters for the Ford 2.7L that were not manufactured to factory specification. K&N re-assured me that all the defective filters have been taken out of circulation.

Let them horses breathe!
Don't know why I sat on changing out the filter for the wife's Bronco (maybe cause the F150 gets all the love). K&N has always been my go to for any vehicle of mine. This extended 18k filter was no exception! Gave the 2.7 more pep and can definitely feel immediate real world response from the get! Wife didn't believe but was thoroughly impressed after driving it for the day. She's a believer now!

Disappointing
It doesn’t fit snug around the intake and my gas mileage DROPPED 1.5mpg after installing it. I usually like K&N filters but this one is trash.
