K & N Cold Air Intake Question?

What are some of the benefits for installing one of these? I'm not too familiar with a lot of the mechanical upgrades on here. Why do most Jeep user's install this and what is the average price for one? Thanks for the help

Re: K & N Cold Air Intake Question?

1. they claim to gain 10-15% horsepower and gas mileage. 2. they look cool. 3. said to be the best "bang for your buck" as far as price/performance gains. runs around $250. i have the AEM dryflow cold air intake, its great for the driver who doesnt want to oil their filter, its maintenance free and gives the same results and costs about the same as K&N.

Re: K & N Cold Air Intake Question?

as noted above new is about $250 used you can get one for $100 to $150.

they can help with MPG but you get a nice sound from the engine so most people usually press the gas petal more.

if you get a high flow exhaust system with the air intake can help MPG and performances better

most get K&N since they are a good brand, also they have a lifetime warranty. so if something get bad like a filter mesh tears, bolt gets rusty, or any odd thing you just call or email and will send replacement parts. i am happy with the one i bought used.

everyone going to have a a different effect on there jeep on car depending on there driving condition and were they drive.

More air in, more responsiveness, and you'll never have to buy a new air filter again.

Re: K & N Cold Air Intake Question?

That looks sharp TJXJWJ! have you noticed anything at the pump? how about throttle response? if you have an exhaust does it sound a little better?

Re: K & N Cold Air Intake Question?

personally i haven't noticed anything at the pump but thats prolly because i like how it sounds when my heavy foot hits the pedal

definetly like the sound as far as power i can feel a "slight" difference.

would recommend it to anyone.

Re: K & N Cold Air Intake Question?

AEM has lifetime warranty as well they make any finish you want too.. painted blue, red, or silver. or polished aluminum, gloss black, and the traditional textured black.

Re: K & N Cold Air Intake Question?

It sounds very appealing, So I take it as straty1987 mentioned, it produces that great sound that is much better than stock lol

I've noticed nothing at the pump...I'm convinced there is nothing on the market you can bolt on and actually experience better fuel economy. Better performance, yes, but economy no.

Throttle response was a bit sharper, and my OEM exhaust sounds a LOT less anemic. It woke up the engine. Money well spent in my opinion.

You can hear it sucking air when you're outside of the Jeep...and I'm not so sure it matters so much what brand (K&N, AEM, etc) as long as it's NOT a metal tube and it positions the filter away from the heat of the motor as much as possible (preferably sectioning it off like mine with a heat shield) you're good to go. Warranties aren't a selling point on these systems. There really isn't anything that can fail.

Warranties aren't a selling point on these systems. There really isn't anything that can fail.

if oyu look into a 3" exhaust system like kolak sells will notices a bit more MPG and power since the jeep will breath better and more air will flow in and out.

only really way to get better MPG is to watch how you drive and find what works best for the most MPG.

like driving at 65 MPH at 2K RPMs i can get 19 instant MPG on the read out
at 75 MPH at 2K-3K RPMS i get 18 MPG on the read out.
i live in NYC so hard to keep this constant but when i take trip to PA and NY and stay at 75 MPH i can get 18 MPG on my 4.7 with not wind but usually get 17-17.5 MPG on the highway for trips

Re: K & N Cold Air Intake Question?

I'm running a K&N Drycharger prefilter...Summit Racing part number KNN-RF-1045DK. Totally worth it...it repels water and you rarely need to clean the actual filter. You just remove the wrap, clean it in the sink, and put it back on. It keeps insects and other misc. funk from getting in the pleats of your cone filter. Plus you can get them in different colors.

The best way to get the most out of your tank of gas is to make sure your ride is well-maintained, that your tires are inflated properly, and that you use cruise control on those longer highway trips. Other than that, like Straty said, it's all about driving habits.
