05 grand Cherokee 5.7L
What are a couple of things that i can do to improve performance on my 5.7. My brother says a cold air intake. I'm trying to improve the respond time for when I'm in the need for speed.

Custom tune, ported tb, cai, exhaust, headers, there are many things that can be done. CAI by itself i feel like isnt much to notice, i would reccomend a custom tune though theyre worth the money

Welcome and ONE THING! Don't go the cheap route. We have vendors for all your needs. I recommend an Airaid Intake first then move onto an exhaust and shoot for a Diablo Sport.

Make sure all the maint. is up to snuff - plugs,CLEAN tb,even run some sea foam through. That will ensure you'll get the most out of what you do. The TB ground mod is the cheapest & quickest (time to do it)mod I can think of, and it helps with throttle response.

How fast do you want to go....?

@ 4.whoa ive done a full tune up and but the sea foam too. And still the same issue. My other choice is CAI or modded parts.

@ escape fast enough to keep up with the competition lol.

Ha, ha...Escape IS the competition. Take a look at our you want to stay naturally aspirated or go the forced induction route?

Whats your goal, and whats your budget?

Better response from throttle and 1,500

^X2 to what FlyinRyan said.

Add a few more dollars into the fund and do heads and cam too if you plan on staying NA.

Cheapo stock SRT8 CAI FTW. Best $40 I ever spent on my WK. Scangauge II shows massive drops in IAT (not to mention I'm just glad to get rid of that crappy resonator intake).
