are throttle body spacers worth the money

[dantheman]

hey guys, ive got a 97' cherokee 4.0 and i was looking to give her a little more umph, and i ran across throttle body spacers and air intakes, and was just wondering if anyone has had any experience with either and werher or not they actually work, thanks

[tupton]

yes they can. A CAI will do more than a throttle body spacer. But to really get some umph you'll need to replace the enire intake/exhaust system: cold air intake, high flow filter, new headers, and a high flow cat

BTW, welcome to the forum. Please visit the New Users Area and tell us more about yourself.

JP Magazine did a article a while back on cold air intakes and ran them on the dyno and with the AEM Brute Force intake which comes with the spacer there was only 1 hp difference when they removed it (The spacer) over having it on with the cold air intake. So I would say not much difference unless you are gonna do the whole package.

Oh come on Tin Badge they at least make a cool sound when you hit the gas.
Ive got a K and N high flow rusty kit thingy. I can feel a difference. More of a difference after the flowmaster exhaust.

yes! the whistle! gotta love it.

I bored out my throttle body, got a short ram intake and got a whole new exhaust and that's been more than enough for me.

TB spacers are for people that have NOTHING else to upgrade on their jeeps.

My thoughts also.

I think I read somewhere that the 2000+ intake manifolds are more free flowing and can free up afew extra ponies when installed on 9x motors. Is this true?

[jeepin304]

good thread i was wondering about investing in an intake, might do it just for the sound i remember is sounded cool when you would rev it up and it sucks in air

But to really get some umph you'll need to replace... ...and a high flow cat

Unless your factory cat is clogged up, you have no reason to replace it. a factory cat will flow pretty good well up into mods. If yuor engine NEEDS a high flow cat, dang!!!! you are making some real power. I have read that in many performance mags over the years. I personally just cut em off the vehicle but... not everyone can do that and still get inspected. just my .02

If you're running larger tires and want to feel more power out of the 4.0 save the $$$ and put it towards a regear. If you're running stock tires......stroker or v8?

An intake by itself is doing nothing.What you feel is the snappy response from a lean mixture.I'm a trained (by DynoJet and Harley) and experienced dyno operator and can write FI maps so I've seen the reality of putting your money somewhere where it'll do some good.Like gearing,tires and good suspension.However if it floats yer boat have at it.
