Re: increase horsepower

Well , I'm sure if you get abetter breathing system youre gonna see gains. Less restrictions, more ability to respond better. In a while when they come out I will prob. get a nice Borla exhaust for my jc, maybe a nice intake. little subtle things for now

Re: increase horsepower

I replaced the air filter and box with a K&N can. It MAY be getting an extra mile or 2 per gallon.

Re: increase horsepower

Hey guys, new to the site, with some suggestions.

Remove the snorkel going to the air box. It's very restricted. Then replace your stock air filter with a K&N filter.

I also installed a Magnaflow cat back system. Should be in production soon.

The hemis are very restricted both in and out. So once you un-cork them a little bit, they run great.

Re: increase horsepower

Jangy, I am wondering, if an air filter change would even have the slightest positive impact on the mpg used, would DC not do this from the start? After all, they spend much money to squeeze out the most performance with the mighest possible mpg ... if a reasonable cheap solution (changes to a filter and exhaust) would do this, why would they not do that? Most of these "solutions" seem to be gimmicks. To tune for more power with a worse mpg result, that I can understand but to have it both ways, I doubt it. Hence I understand Intreper's suggestions as they underline what I had posted as a link earlier about the Hemi engines in general.

Re: increase horsepower

Cold, forced air usually makes more power than the hot air drawing off of the engine like you will when you remove the snorkel, so would it be a good thing to remove?

It's a good thing to remove because its very restrictive. Before removing mine I ran a thermometer inside the box, with before, and after the removel readings. They were identicle. The only time you're going to suck in warmer air is when sitting at idle. Same effect will happen with any cold air intake. You want the colder air possible at acceleration and wide open throttle (WOT). YOu get the most benifit of it at those times.

With the snorkel removed, I gained 2.2 average miles according to the evic during 25 highway mile trips to work.
The butt dyno likes the removal of the snorkel a lot!

Go to ebay motors and run a search for "jeep commander air filter". You will then see a few vendors that offer the K&N filter. Its the same size filter element available for the Hemi Ram. I paid like $45 for mine if I remember right.
