## Description

Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: This IS the intake you've been looking for - 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.
Review: Great intake for the money - Hard to go wrong. Direct fit for my Trailblazer and it's one of GMs best performing intakes.

## Questions & Answers

**Q: Will a 4bolt 92mm throttle body fit this intake?**
A: Yes

**Q: If I buy this for my 2004 5.3 Silverado what all will i need beside this and 4bolt tb?.any and all help and info needed! Tks**
A: On top of what others have mentioned, You'll need an x-link cable to hook up the new TB. And a fuel rail for the TBSS intake, as your truck intake rail won't fit. And if you're going to get the fuel rail, you may as well find one with the 50lb injectors from the flex fuel variants. Then you'll need to find some adapters for the harness. And research whether your system is returnless or not. You might not need some of the parts mentioned.

**Q: Will this fit a 2003 silverado z71 5.3?**
A: It will fit any year LS based engine. Make sure you are using 4bolt drive by wire throttle body.

**Q: will this direct fit onto my 07 Avalanche with the 5.3L?**
A: I believe the 07 avalanche comes with the NBSS intake manifold which is the same as the TBSS intake.

### ⭐⭐⭐⭐⭐ Great intake for the money

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

### ⭐⭐⭐⭐⭐ OEM part, easier than cleaning old one.
*by S***S on October 8, 2022*

Top notch for service replacement part. If you are sure about part number, order without fear. I’ve purchased a few different ones because cleaning the old ones prove impossible, just easier to replace and not too expensive.
