Questions & Answers
Q:

Will this work for my three bolt LS6 DBW throttle body?

Asked by YESICA on March 04, 2018

A:

The LS6 is a three bolt throttle body. So shouldn't it fit on this adapter? Then bolted on a 4 bolt intake?

Truck is running!

Summit RacingSummit Racing Verified Purchase

ICB-551511
Had installed a Trailblazer SS Intake manifold on to my truck and was running and idling pretty rough with the China throttle body (Gave it a chance for the price) plus the stock intake tube wouldn't fit on the new throttle body either so I had to reuse my stock throttle body, this adapter came in 2 days! Just as other products I've purchased before on Summit, but it only came with one gasket (the round one) and not the other that is needed for my stock throttle body. Had to reuse my old one and cut a few pieces off to make it fit but overall adapter worked and helped get my truck running again. ...read more

It fits

The item fits an ls3 intake to the old lq4 throttle body but the holes were just enough off to where the bolts were tight. It will work but you get an uneasy feeling when you tighten it down with the plastic intake. Mine worked and I am happy with it.

Summit racing is where you go for your racing needs. Orders come in fast & easy to install/ directions also come with your purchased item or items. Love the decals they send, so you can support them in any way possible by sticking them where needed.

Great product. I was able to adapt my 3 bolt throttle body from my factory 03 Silverado 5.3 intake manifold to a newer 4 bolt intake manifold. A lot cheaper then changing to a newer 4 bolt throttle body
