There have been some inquiring about your K&N set up. Have you gotten to it yet or just doing the magnaflow first? An almost 8hp gain doesn't sound too bad for not going internal.

Good installation instructions here:

Something I didn't realize before, that dyno on K&N's website is for the 2.4L Dodge Caliber. That horsepower gain may or may not be realized on the Compass.

Would be interesting to see the difference in throttle response though.

Be sure that while you install the intake, you remove the negative battery cable from the battery. It will need to be off for at least a couple of hours to reset the computer so it can learn new timing tables with the increased air flow. This will also help keep your fuel mileage from taking a dump.

Does anyone know if installing one of these would have any effect on the warranty?

Don't get me wrong - I like the idea of 5% more horsepower - but with an engine and transmission being of recent design, I like the peace of mind that comes from having a powertrain warranty.

Its illegal for the dealer to void your warranty for an air intake UNLESS they can prove that the intake caused the problem.

Example: You install the intake and forget to put the filter on it. You run the engine for 10k miles this way. The cylinder walls are now gouged and the piston rings are complete crap, and they void your warranty.

K&N AirCharger High-Flow Intake/Cold Air Intake - Merged

Just received and installed it. Overall, I like it so far. The install was pretty easy. Other than the step where you have to install a sensor into the new tube, it was a sinch. All I needed was a flat head and plyers. Picked it up for $220 shipped
Positives:
-Considering I havent really gotten to test it out, I did notice a difference in HP. I've had my Compass since November... Noticable difference.
-Looks Good
-Hope there's a difference in gas mileage as they claim
Negative:
Little loud when you punch it - kind of sounds like a lawn mower

Overall I like it so far. It's a little late now but I'll take pix and comment on gas mileage in a bit

I hope that it’s a “Tim – the tool man – Taylor” Lawn Mower ! This sounds like a good way to go. Do you notice much difference off the line or is it in the driving range? And were the instructions on the website pretty accurate? Where did you find it for $50 less than list?

I pulled these from the other thread.

I notice the biggest difference off the line and while I'm on the highway. K&N included paperwork guaranteeing a gain in 7.9 hp or your money back.

Regarding the directions, they are really accurate and it is that easy. Other than squeezing into a couple of tight spaces to get the stock parts out, steps 15 & 16 were the hardest. The sensor is about the width of your thumb and the hole is about the width of pencil. It doesnt help that it says that this is fragile part. Its downhill before and after those steps.

I searched for the best price and I found it here...

Sounds really great! Keep us informed on the mpg, not that it could suck that much gas but you could put your foot in it more often . Would just be nice to have the extra ponies when you needed them regardless of the mpg!!

Nice price too.

Nope. COLD AIR! Higher volume, less restriction.

http://www.jeepforum.com/forum/showthread.php?t=369325

I just rechecked the links up in post #2 and they went dead. Posted a new link back there.


"They use only non-metallic rotationally molded tubes that can reduce intake air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow “chain” robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER."

i like the way that looks. also having the airfilter sitting where it is in the pic would help if u ever do water crossings. im guessing the same set up is gonna be used on the patriot too.
