3.7L with a 4.7L CAI?

yeah, for $300+, I dont see the return in hp or mileage to be enough.

Amazon and eBay are where Ive always got my intakes and never paid $300+.. Although gains are minimal for normal driving, when WOT Ive noticed a huge difference. I do realize these arent cars by any standards hahaha but for someone with a heavy right foot, the intake is a great upgrade to get better performance for an easy install, IMO.

haha yeah i do tend to have a heavy foot. and i havnt priced any intakes yet, but if there is any improvements that are even just a little bit noticeable would be great.

Go to Amazon, they are having ridiculous deals right now, I got my k&n for $213 shipped!! The gains are minimal, but the XK will feel more "free" is the best way I can describe it. With an exhaust and tune, you will see considerable gains over stock. Im realistic, I know that for the $$$ Im going to gain 50hp, but it improve the performance and mpg slightly.

The heavier your foot, the more you'll notice. Think 5-10 (max) HP gain at peak RPM. The gain dwindles quickly as RPMs decrease (the entire power band is not increased).

But remember.... with that heavy foot comes decreased mpg lol.

haha yeah matt ive noticed that but i enjoy listening to that flowmaster too much to really care. And it also doesn't help that 99% of my driving is city so its crap already but i love my jeep and wouldnt get rid of it. Unless i had the option for the 4x4 or hemi

alright thanks matt, yeah im always looking at something to add to it for performance or appearance wise, and i didnt even think of looking at thorttle body spacers.

Lower MPG's BIGGER SMILES!!!!!!!!!!!!!!!!!!

Alright thanks, ill be looking into that. Ive already got a super 44 flowmaster on it so a nice k&N would be nice. Im also thinking about port and pollishing my thorttle body too. would that help also? I just want to get every ounce of power i can out of my little ole V6!

While I'm a bit skeptical on the actual gains for a NA engine (it would be bad engineering if the TB was a bottleneck) ... port & polish sure doesn't hurt and is worth spending a few hours playing under the hood of your Jeep (I look at it more of a "fun" mod that is likely to have performance benefits as well).

Stay away from TB spacers though. That's a waste of money.

Edit: I think AJ ported his TB and liked the results...
