I had problems on my throttle body throwing engine codes due to a dying TPS sensor and the throttle body also had a stripped screw hole, so I decided to buy online a new throttle body. I bought a Granatelli 62mm Twin throttle body because it comes with all the electrical and TPS sensor on it. (Ive also been hearing some pretty bad things about the company now though which is getting me nervous ) but the main issue im having is that it did not come with the rubber elbow coupler!!!! I have a JLT intake and the diameter of the elbow is about 4 1/4" inch while the TB is about 5" maybe more? The rubber JLT elbow fits better inside the TB rather than over it, so until I can find a solution Im pretty much screwed. I tried finding couplers and elbows at autozone, lowes, homedepot, checker, pepboys, ect. Any ideas???

Thats not cool. Its supposed to come with one. Look here: GMS Twin 62mm Aluminum Throttle Body (05-10 GT) - Natural at AmericanMuscle.com - Free Shipping!

Where did you buy yours from?

I got my JLT elbow to fit over a 5" TB opening, it just takes some muscle.

Maybe try some gojo handcleaner or dishsoap on the inside of the elbow. That's what plumbers use to put rubber couplers on cast iron pipe.

use very little and if you do use the gojo use the stuff without pummice (the sandy stuff) WD-40 works too and a little heat and i stress a little will help too. like by a hair dryer or heat gun set on low.

A little motor oil might do it and might not be as hazardous considering most cars get blowby anyway.

I got the TB online from an ebay seller, the seller is willing to give me a full refund which is nice but I would still like to get it working if I could find a proper coupling to fit it instead and save myself the hassle of reshipping and waiting. Unfortunately though I wasnt able to stretch the inlet of the JLT elbow, Its just way too small to reach over the lip of the TB. And Granatelli doesnt sell the couplings separately, I might just fabricate an adapter from another reducer coupling and just attatch it to my JLT's existing elbow. Im just concerned it the extra coupling will make clearance for the CAI because it would mean pushing out the JLT intake another 3" from the TB, I'll post pics of the results if I can get it to work out.

here is what you do, take a string and measure the circumfrence around the inlet opening then transfer that string length to a tape measurer, you then have your TB inlet size. google (as an example) Drain coupling 5" to 4" and there you go.

here is a 5" to 4" if it so happens to be the right size.

Drain Coupling, 5 to 4" Straight Adaptor, PVC Rubber

it would be best if you could find a 90* but i didn't look too hard, try AEM too.

*UPDATE* I contacted the ebay seller who sent me the Throttle Body and he had been very helpful and agreed to send me the extra coupling to my door at his own cost. In the mean time, Im still fabricating a coupling of my own to fit the TB on so Ill have a running vehicle. It doesnt fit very well and makes clearance for the CAI a tight squeeze but Its still a work in progress. Im using the Pluming coupling above that was suggested and a 2" long 4" diameter PVC pipe to connect the JLT elbow and coupling together.
