2000 jeep cherokee sport questions

[amiller]

Hi guys I'm very glad that I found this fourm. I recently bought my jeep and I'm looking for some ways to get some more horsepower out of it. I'm not rich or anything I'm just looking for some somewhat simple tweaks and replacement parts. So any tips tricks or opionions plz let me in. thx

-Cold air intake, one that actually has a shield and draws cold air from the front of the vehicle. Don't get one of those cheap ebay ones that is just a piece of aluminum tube and a filter. Don't get a Volant as it needs modification to fit under the hood and doesn't offer a real shield. S&B has a nice air box, but once again it needs modification to fit under the hood.
-62 or 63mm throttle body. See strokedjeep.com
-2.5" exhaust.

These made a very noticeable difference on mine with the stock 4.0L

now the board throttle bodies do they need any extras to be mounted or do they just plug and play basically ?

Nope, just swap sensors and bolt on. The only thing that might have to be done is open up the intake manifold opening, but I can't recall what size stock is.
