Originally developed for demanding race applications, K&N's Premium Wrench-Off Oil Filter has become a favorite among consumers for its durability and easy removal. Most of our automotive and marine oil filters come with a 1” nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. To satisfy the demands of racers, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The drilled hole on the nut provides for safety wire attachment. Our oil filters also use a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration.

I think your products are well designed and thought out, easy to install and they weather well. I hae a 20yr old ford 1996 f450 and my K&N works just fine, My next project might be my wifes 2014 dodge charger 5.7.

I could tell a huge difference after I put a k and n intake in my 2002 Ford f350 7.3 power stroke. Very happy with this purchase.

I love this K&N Air Intake. Look's so much better than the stock Ford Intake that came on my 2006 F150 STX. The sound is Awesome I did not think i would be able to tell a difference in the sound but along with my FlowMaster Exhaust you can tell it's not stock, it sounds great, when you step on it you can hear the Air being sucked into the Intake. On MPG, I've been using it for about 2 week's now, I fueled up and almost run it all out before installing the new Intake, then fueled up again after it was installed and drove the same way back and forward to work. I can tell some change in MPG, it really does help. There is also a change in the  Throttle response and HorsePower. Installing this Intake is easy to do, and when you open the hood, It's the first thing that hit's your eye's. The only thing i had a problem with is the Intake tube had a spot on it about the size of a half dollar that looked like it had sand paper took to it, almost like the tube had been used before. But luckily it was on the bottom of the tube so when installed you never see it, so no big deal really. All in all i give this K&N Intake a 5 out of 5, I love it.
