Which one works better? Can I run them both?

 

Derp.

What?

 

Neither are going to help much. Cold air intakes and throttle bodies and spacers all work together except spectre cowl intakes won't work with a throttle body spacer because the spacer raises the intake tube and the hood will hit the tube. Any other regular cold air intake in place of the stock air box will pair up with the tb spacer. Expect nothing more than a little noise from the intake

 

Don't bother with a tb spacer get a bored out throttle body and personally I love my afe CAI

 

98cherokee531 is right, I went with the spectra so I could do water crossing's with out having to worry about sucking water into the motor. For my throttle body i went to http://www.jeepersandcreepers.com/13601.html

according to my research through K&N, they've been able to claim an additional ~8hp with their tubular cold air intake...that's all well and good, but in terms of increased efficiency, that's certainly not Earth shattering. The throttle body will most likely add a few HP as well, but I tend to think for the most part the gains you'll make will mainly take the form of sharper throttle response, rather than purely horsepower gains. You certainly could use both of them together, but there might be some other modifications that are more worth your time.

 

you can bore your own throttle body i did mine..also made my own cold air setup

 

Go HERE this should help you

 

Throttle responce is Awesome...5 speed helps

 

where you at in Alaska ?My sister is in ankorage prob. spelled wrong

 

Anchorage,,, I'm chillin in Juneau, but have been all over Alaska

 

looks nice there...

 

We are lol It is, we have no roads to Juneau have to fly in or boat in. I have never been to the lower 48 cause I have no need to lol.

 

If you go off road a cold air intake will suck up water,Most on here use a cowl intake or true snorkel.If your xj is 87-90 http://www.quadratec.com/products/17006_7100_07.htm or 91 up http://www.quadratec.com/products/17006_7100_07.htm and 91 up http://shop.trailheadoffroad.ihostne...ctid=XJCI91-01

 

A cowl intake is a real cold air intake well unless its hot outside then its a less hot intake.
