Restriction is often found between the factory air filter and the engine which can reduce the benefit of a K&N air filter. K&N 63 Series air intakes virtually eliminate air path restriction by completely replacing the air filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which translates into an increase in vehicle horsepower.
This is not for the 4.6L 2V(16V) engine. Pay attention to your vin number if you are not sure of your engine size. If your engine is a 2V(16V) the eighth digit of your vin will be a W,any other letter or number this kit will fit.

Purchased this filter for my 2011 Ram 1500. Right off the bat I noticed engine performance gains. It gives a more throaty sound to you vehicle as well. Recently installed Flowmaster exhaust system and i must say its highly recommended. Get rid of that stock equipment ASAP!

Notice a little increase in HP. Makes the engine sound great.

Cold air intake
Everything was pretty easy, but the instructions aren't clear on what exact screws, etc. to use. But other then that awesome. sounds good and you can feel the increased power.

K&N 2012 DODGE HEMI 5.7
Took awhile to ship to my house from the lower 48 but once i received it it was installed in 20 min. Throaty sound and very impressive power increase was evident. If you have a vehicle with stock air intake.. change it. It's the #1 modification and most cost effective you can make.

Hemi sounds like a HEMI!
I really feel the power added and made the Hemi in my 2012 Jeep Grand Cherokee grunt and growel like a V8 should.

ABC, easy as 123.
It allows me to use only 2000rpm's to get up to a comfortable speed vs my engiene working harder to do less. I have a lift and extra karge tires, so for a rock crawler, it is very suitable. I would also grab a throttle body spacer and a hood kit.
Sorry, this is not legal in California. Thank you.
