Granatelli GM LS / LSX 105mm Black Billet Drive-By-Wire Throttle Body – GMTBLS105B

Is the 105mm Right for Your LS?

Choose the GMTBLS105B when your LS runs a 105mm-inlet intake manifold, such as the Granatelli ZILLA 105mm, and the engine can use the extra air: a bigger cam, ported heads, high RPM or boost. On a stock-style LS3 intake, the 103mm GMTBLS3B billet or GMTBLS3M cast is the usual pick. See every size in the LS throttle body collection.

GMTBLS105B FAQ

Will the GMTBLS105B fit a stock LS3 intake?

It is made for 105mm-inlet intake manifolds such as the Granatelli ZILLA 105mm. On a stock-style LS3 intake, the 103mm GMTBLS3B (billet) or GMTBLS3M (cast) is the usual choice. Verify your manifold opening, bolt pattern and clearance, or call 1-805-486-6644.

Do I need a tune?

Yes. A tune is required after installation for proper idle quality, drivability and performance.

What connector does it use?

The factory-style GM 6-pin drive-by-wire connector. It is a complete assembly, so nothing transfers from your original throttle body.

What is the difference between GMTBLS105B, GMTBLS105 and GMTBLS105P?

The finish. GMTBLS105B is black, GMTBLS105 is natural and GMTBLS105P is polished. All three are 105mm billet drive-by-wire throttle bodies.

How much boost can the GMTBLS105B handle?

It is rated for up to 35 psi of boost, the same as every Granatelli LS and LT throttle body.

Will a 105mm throttle body add horsepower?

Only when the throttle body was the restriction, such as on big-cam, high-RPM or boosted LS combinations with a 105mm-inlet manifold. Granatelli Motor Sports does not quote a fixed horsepower number.

What is the warranty?

90 days, with optional extended 1, 2 or 3 year coverage at checkout.
