K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2015-2023 FORD: Mustang, Mustang GT, 33-5029

Good

The description says it fits the Mustang GT, it also fits the 2.3 ecoboost. I have K&N filters in all 3 of my vehicles. The 1st time they need a filter I put in a K&N lifetime filter. They work great and they are far less expensive than throw aways, over a short period of time. I do the same with my motorcycles. They have never let me down.

Fits perfect, haven't had the chance to see if it adds more power, throttle response is better and the biggest instant change was MPG. Easily 3 to 4 right out of the gate. That will commeserate with how heavy your foot is.

Fit well in 21 mustang eco boost. Don’t know that it really gives that much more performance but who doesn’t like a K&N

Very good

I would like to leave a very positive review. But there is a problem with using this type of filter in some vehicles. In my case - a 2005 Chevrolet Equinox with the 3.4 liter engine, some of the oil from the filter affected the MAF sensor (an air flow sensor) and caused the engine to start idling way to high (1500-1900 RPM). I will have to either clean or replace the MAF sensor as a result of installing this filter. Otherwise, on the positive side, once this filter was installed, I could instantly feel the difference in the engine performance. It's not a *big* difference. But on engines like my 3.4 liter that can really benefit from a little more air flow, you can feel the improvement as soon as you accelerate onto a highway.

Easy installation and seems to breathe better
