Webber is the OEM manufacturer of our throttle bodies. nothing performance about them

I got a Modern Performance 60mm TB on my car, when I put it on I had my intake manifold gasket matched and polished. Hands down the best N/A upgrade I ever did to my car. The kick in HP that I felt from that combination was amazing. If you do upgrade your TB, take the time/money to do it yourself/pay for a P&P on your intake manifold.

Definitely upgrade to a 60mm i have a jeep 60mm tb and my manifold
tapered to 60mm. its not a hard to fab it up it took me about 2 hour to do!

And it opened up my top end... love it

So what years and models of Jeep TB's bolt up?

i think it only works for 1995 -1999 because those are the only years they used the Chrysler 420a motors

i think its early 90´s 91-94 or something like that, here you can find instructions about this

Quick reminder to guys going for Jeep TBs, if you want a 60mm get your TB off of an automatic. The manual Jeeps neck down to 55mm (which still helps, or you can bpre them out to 60mm)
