    • This IS the intake you've been looking for
Review Image by 1Harley1Camaro 1Harley1Camaro
Truck owners rejoice! This is the famed GM TBSS intake for cathedral port LS engines. This is the best flowing manifold for your stock or swapped LS powered vehicle if you're looking for torque improvements. Better than the LS1, or LS6 GM manifolds and much better than the china.com shiny aluminum aftermarket manifolds at anything but the higher RPM ranges. Of course, if appearance over performance is your primary consideration, you won't be happy. This manifold is still an ugly plastic stock GM manifold. Only slighty better looking than the normal truck manifold. Does NOT come with intake port gaskets or fuel rail so you'll need to purchase those separately. This intake is configured with a 4 bolt flange for the throttle body so if you intend to use a 3 bolt cable operated throttle body rather than a drive by wire unit, you'll need an adapter. ICT Billet makes a highly rated one. ... show more

    • The best price anywhere for a GM OEM TBSS intake!
This truly is a GM original TBSS intake manifold which people on eBay try to sell used for $200+. The price is unreal. It even came in the GM factory molded case with foam inserts. Know that it is bare and does not come with the manifold gasket, gasket for the throttle body, bolts for the throttle body and bolts for the top cover. If you are swapping this out from your original, you will have to reuse your bolts and purchase new gaskets. I went with Fel-Pro gaskets as they have not let me down. ... show more

    • Tbss intake
Purchased to install on my 01 Silverado 5.3 Fit perfect with the trailblazer ss fuel rail and stock injectors all went together great do have to change up purge valve and modify throttle cable bracket or get tbss style throttle cable bracket to work also need 4 bolt throttle body would purchase again ... show more

    • OEM intake
Nothing to dislike on this intake. Great upgrade for Gen3 LS trucks. Intake does come BARE. So you will need gaskets, fuel rail, map sensor retaining clip, Brake booster fitting and NNBS evap solenoid and hoses. Also need a TB adapter plate if reusing 3bolt TB. Gen3 injectors will work fine with this intake and appropriate fuel rail, also original map sensor works too. Cheaper to buy this then what some are asking for used ones and it’s new, clean and not full of engine oil like a used intake can be. ... show more

    • TBSS intake manifold
It fit my engine. Not sure how I feel about the injector location in relation to the intake port. But it came in a very nice box. Un-damaged.

Hard to go wrong. Direct fit for my Trailblazer and it's one of GMs best performing intakes.
