i put a tpi i air cleaner off a 87 i-roc what is the best thing to use to fill the gap between the air cleaner and the thottle body. i have a 92 rs 3.1.

 

I used a few inches of 3" muffler pipe. Quite heavy. Some muffler shops carry aluminum pipe. Or buy one of them cheap euro intakes, and hack it up.

 

you could go to lowe's and get some ductwork (like a reducer pipe) or something, that would be relatively inexpensive.

 

ive asked this a few times and never get a answer, other than that the tube for the 305 tpi intake is short than the one for the 2.8/3.1 intakes...what is the other differance? they look the same to me

 

The one on the tpi is shorter, it is also too elipsed at the other end for the fact the TBI is dual 48mm, where ours is single 52mm.

 

my o my got to advanced auto and buy there air intake duck..its like 8 bucks but its ment for this type of use and workes good lookes good...heres a pic of mine...

ps its in a green and yellow box!

 

don't you need a MAF sensor there? i have the iroc air cleaner and i need the MAF sensor....look at pic....

 

Not with a 3.1l he doesnt. No mafs on ours, MUAAHHH

 

And that's why there's the problem, F-bodeee... need some pipe to fill the gap.

Xceleratemaro, that's the same hose that I used for my cold air intake! Cool; didn't know anyone else found those. I like the metal coil inside the hose; keeps it from collapsing. (And that's important when the hose goes inside the inner fender on the driver's side!)

 

explain the dual 48mm and single 52mm to me im confused

 

The TPI engine has two 48mm holes side buy side like .... oo........, the v6 has one slightly larger hole like....O....... that.

When two of them are side buy side, it is very wide, and the hose diameter is almost 4", where ours would fit a 3".

 

yea tom im vary pleased with it!
