Easy ISR tube?
The upper part of my intake tube craked and fell apart around the TB today... i managed to patch it with a rubber horse and some sealant... well aty least enough to make the truck run im sure it still sucking in some air... but well i figured this would be the time to do an ISR mod
I just want to know whats the easiest thing to replace the intake tube with? like andthing I can buy at homedepot with out having to have a piece of exhaust tubing bent for me? and also what is the best way to go about the fittings? should i leave the closest line to the TB off as it seems to just dump dirty air back into my intake? |
I found a 3" 45 degree pre-bent exhaust tube worked awesome from napa! I did not put any of the old fittings back on, just put a filter on the PCV vent.

Mine cracked at one of the rolls in the mold where it bends and cause very bad bucking (whooop whooop) problem whaen I accelerated and the engine torqed and opened the crack up sucking air , couldn't see it very easy until I removed it and then I could see where it split , I bought a new one from the Dealer for $40 and replaced and that way get to keep my positive crankcase venting working properly :) .

MRecio...run a search on ISR mod. There's several threads with what others have used and what has worked. I got some 45deg angled schedule 80 PVC for mine. Fit just fine. There's other options, though.

I did mine with 3" exhaust pipe cost me $3 at a local muffler shop. My problem was finding nuts to fit pipe thread.
