"NEW" TBSS Intake Manifold (with injectors and TB)from GM? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Haven't seen any feedback on these... https://www.ebay.com/itm/28537864550...mis&media=COPY

Looks like a cheaper alternative to the Dorman intake that looks like an LS2 intake but performs like an Trail Blazer SS intake... with higher flow fuel injectors, and throttle body, sounds too good...

The LS2 Dorman does not include TB or injectors or fuel rails... https://www.summitracing.com/parts/r...make/chevrolet

Anybody tried one?

Pretty sure it is legit. Glens Auto Performance is a real company that I have bought TBSS related stuff from. I seem to recall a couple years back they bought (possibly) all remaining TBSS intakes available from GM. I think I saw it on their instagram IIRC. Like pallets of them.

TBSS intake, and nearly identical NNBS intake are GREAT options for LS engines if you have the space and don’t mind the look.

Thanks, that makes sense, don't see TBSS packages out there by anyone else. If you buy the parts separately, cost would be over $880. I have a LS6 intake, with 30 lb injectors and 78mm TB, which might be enough fuel/air for a freshened up LQ4 with a SS2 cam, stock heads and headers. Agree, the TBSS is not purty.
