quick question to thexjfiles, when sending the old throttle body back for rebate, what do we need to include in the box(besides throttle body). Such as paypal info or cherokee forum user name? or anything else?

Price is $80 shipped anywhere in the US. If you return a core afterwards, I refund $25.
These are bored, glass beaded, cleaned, greased, assembled, and adjusted. Ready to bolt on. Just add your sensors.
All you need to do is flash the ECU..which I include instructions on how to do it properly.

Cant believe I just read through 78 pages really sucks that the renix tb is to thin... just wondering though I seen earlier that the renix is 52mm would there be any benifit to possibly going to 55mm or maybe a 57mm? that way it wouldnt blow through and u wouldnt have to mod anything to run an HO tb or would there really be no difference. would be kind of Interesting to find out.

Yeah, I tried to go to 60mm, just so we could put the HO throttle plate in it and blew a hole thru at about 59ish. That said, I could bore it to about 57-58 ish and supply an HO throttle plate that you would have to file down to the proper size, and open the slot in the shaft. Let me know if interested, I have one or two Renix cores at the house.

Got mine put in today and even with a high flow intake filter and magnaflow exhaust with 2.5" pipe there is still a noticeable increase in throttle response and acceleration.
Thanks Dennis!!!
