Review: K&n air filter as described - It fits, its a k&n, wasn't very oiled but inflation has been hitting us all lately 😂
Review: least expensive Cold Air Intake upgrade - This review is for the "K&N High Performance Replacement Air Filter" in my '14 Mustang. This is the second modification for my car (the first was "OBJECTS IN MIRROR ARE LOSING" decal) since I got it. I consider this a power upgrade as better air flow results in better acceleration and more horse power. The install was easy; pop off the air filter cover, remove paper filter, install cotton fiber K&N filter. The cotton cloth will be much better at catching dirt and will not "plug up" like the pores in a paper filter. The cotton is oiled so dirt particles get stuck while the air flows up, down and around the cotton fibers. I do understand that this is not a "total CAI kit" but more of a step (in the right direction) for my car. This filter will not void my warranty nor does it require a tune. The cost is very low considering this is a lifetime filter; just wash and re-oil. Once I own the car more - I can get the CAI, tune, exhaust kit.

### ⭐⭐⭐⭐⭐ Great Filter. Worth the price.
*by T***I on May 12, 2015*

The quality of the filter is much better than the stock one. Also the disposable one that you can buy of the shelf does not even compare to the K&N. The best part is that they are reusable. I noticed a slight improvement in my mileage (0.4mpg) but that was expected as the previous filter was very dirty. The exhaust note also sounds a little deeper which is nice. If you are trying to increase you hp go for a CAI as this will not make a difference. Overall the filter is definitely worth the higher price. Keep in mind that while the filter can be cleaned you will have to buy the cleaning kit from them ($11.00). The main reason I got this filter is because of the higher cfm.
