Low-Temp Thermostats increase horsepower and control engine temp by consistently metering water flow throughout the engine instead of simply cycling open/close, which in OE units creates temperature spikes.

trentsjk Thats a very nice offer, to bad I live in Omaha LOL. One its gives the jeep a very nice sound, I also got better mpg, and I could tell when I got on it the power was up. and to test this I did get a guy with the same jeep as mine gears, wheels tires, soft top- ok and we raced them, I pulled a way every time. I have 35's on now and it needs gears, but I still get by, not as quick, but it sure does sound good.

MTH Run a "titles only" search in the JK section for "intake". You'll find dozens of threads on CAIs. They are not particularly well-loved.

They make a big difference in sound and an itty-bitty difference in performance. That's it. My guess would be they add maybe 3 hp at usable RPMs. You've got to balance that against their cost and any potential impact on your engine.

I suppose more would be accomplished by doing intake + viper throttle body + headers + exhaust, though I don't know how much. I saw a guy on another forum who did intake + headers + exhaust and got 9 more hp on dyno runs. That's 9 more hp and better sound for about $2300 worth of gear, assuming you install it yourself. Worth it?

I just have a K&N in the stock air box. Just didn't want to buy a CAI and then find out it's useless unless I upgrade the exhaust, headers, and whatever else.

Cold air intake

If u install a cold air intake, is it best to follow it up with a new exhaust, headers, etc? Or does the CAI do the job it's supposed to without it?
