Kit??? Someone is wanting some $$$ from you if they are selling a "kit". I did this on my 89 for about $8 and I bought all the parts from NAPA. I did not see any performance gain, just cleaned up a busy part of the engine Looks good

throttle body coolant bypass kit?

If so i rigged mine with a pvc pipe made for hot water.
Works like a dream and was about less then 10$. Can't beat that.
Improvment not really noticable but it helps keep the TB allot cooler.

agreed - DO NOT BUY THE KIT

go to the parts store or auto zone and get two black plastic caps in the Emergency Part section (has door *****, lock caps, and other assorted interior parts you tend to loose over the years).

I pulled the hoses off the TB, capped it off, and reused one of the clamps to re attach the 1st section of hose right back into the port along side the passenger fuel rail.
Might have cost me a dollar fifty for the caps if that much!

the kit on Ebay is the BIGGEST rip off- btw.

For a '95 especially, no kit or even parts are necessary to do this. Remove the coolant hose from right side of the TB to the pipe. You can discard this hose. Remove the hose from the left side of the TB and hook it to the pipe where the other hose went. This hose can be shortened before reattaching as well. You're done.

yea... i didnt even use any parts at all.... i just took the passanger side hose off, and attached the drivers side hose to the place where the passanger hose went. who cares about capping the pipe ends??? not sure if it did anything... but it certainly didnt hurt.... and while the intake is off, you can take your mass air screen out (if you have a mass air car.. i forgot to see what year you have)
