The micro-glass media has very good cold flow characteristics while providing excellent capacity and efficiency. These oil filters have a premium HBNR base gasket for sealing, a silicone anti-drain back valve and a dichromate plated backing plate for corrosion protection. This heavy-duty oil filter was specially designed for a high compression turbo diesel engine's tight tolerances.

I love your guys products! I just put a FIPK generation 2 cold air intake (part # 57-2541) on my 2000 Ford F-150 XLT 4x4 7700 with a 5.4 liter. It adds so much! It sounds like a different engine! It has such a sweet growl to it. It even makes the truck sound like it has an exhaust system on it. I was extremely surprised by the added power to it aswell. But, the added fuel mileage is a LIE! I cant keep my foot out of it! Come on K&N, how do expect people to get better gas mileage when we install your incredible products on our vehicles? I will definetely come back to your products as long as I own a vehicle. Thanks again!

2012 Nissan Frontier Pro 4X 4.0L. It is very loud at high rpm. It did add hp and tq from about 3500 rpm to red line. About 4500 rpm to red line it is louder than my dual exhaust. I would suggest this to anyone. I'm looking at getting one for my wife. Very good cold air intake.

I tried the kit 57S-4000 with exchange filter from K&N with the new lid for the air box. Just looking at the product and thinking about the idea of putting in a bigger filter by making a new bigger lid of the air filter is in my world is brilliant. The work putting it on was super easy and with good fittings, and with an easy manual. The performance was noticeably better through all the revs. And the best part of all was that the fuel consumption went down below the car manufacturer’s data. This kit cost a lot, but it really works and it will save you fuel, and by the time it will actually pay it self off. I recommend this K&N kit to all Volvo V40 D2 owners.
