Questions & Answers

If I purchase this for my 2004 5, I will be able to use it in my 2004 5. Apart from this and a 4bolt tb, what else do I need for a 3 Silverado? Any and all information and assistance will be greatly appreciated! Tks?

You'll need the new style purge valve, injector spacers if you're keeping your fuel rail, and the fuel filter from the 2005 vet with the internal regulator if you're going with the return less fuel rail.

Will this fit my 2007 Avalanche with the 5.9L engine? 3L?

I believe the NBSS intake manifold, which is the same as the TBSS intake, comes standard on the 2007 Avalanche.

What's up with this manifold? I just got it and there's no mounting bold. ?

There are no hardware-equipped intake manifolds that I am aware of. Especially at this price point.

Will I need to move any wire harnesses, clamps, or other equipment?

If it's on a truck or Trailblazer SS, the answer is no. If it's for a Camaro, Corvette, GTO, or CTSV, you'll have to rearrange things. Although this intake is taller than any of the car applications, there are plenty of aftermarket parts for relocating anything on an LS motor.

It's a nice upgrade from the cathedral port vortec truck heads of the past

5/5

It's a nice upgrade from the cathedral port vortec truck heads of the past. Note: You'll need to modify your fuel rail or borrow one from an nnbs truck/Trailblazer SS if you do this.

For the money, this is a good intake

5/5

I'm going to use it on my LQ4 project. It's difficult to beat this TBSS intake manifold's performance and price. At a fraction of the price of a dealer, you can get OEM quality for a fraction of the price. However, you will need to purchase all gaskets.

It functioned as expected

Make certain you have new gaskets and that you torque it properly.

If you're looking to replace the intake on your lq4 on a budget, this is the kit for you. This is a high-quality part that is superior to a quick intake.
