Great filters. Been using them for 25 years and won't use anything else. Needed a pair that could flow enough air for a 800hp turbo engine.

Great filter
Like the previous review, I too purchased this filter to have as a back-up and to swap during cleaning. The sheer size and 360 degree filter element design improves air flow, thus performance. Since I installed the FIPK on my Ford Ranger in 2005, I have noticed much improvement in mileage, power and engine response. The loud and noticeable "hiss" while air is drawn in is normal, and an indication of how much volume of air is drawn. I would also recommend cleaning long before 50,000 miles, perhaps no longer than 15,000 when the fuel filter needs changed. Be sure you know the proper inlet size and filter dimensions before ordering to ensure fitment and clearance. This filter is a K&N factory replacement part for my FIPK system, and perhaps others as well. Very good build quality, strong, and easy to clean per instructions.
