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.
