In stock!
Part# 54039B



The BLACK version of the FAST LSX 92mm Intake Manifold delivers proven bolt-on performance gains with a clean eye-catching appearance.

The patented LSX™ 92mm Black Intake Manifold from FAST™ is the only three-piece Gen III (cathedral port) composite manifold proven to deliver increased performance without compromising bottom-end drivability or high RPM power. For both street and racing applications, the new black intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines and is designed to work with the FAST™ Big Mouth 92mm Throttle Body™. The FAST™ LSX™ 92mm Black Intake Manifold maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low RPM torque. While the FAST 92 intake manifold delivers terrific performance right out of the box, it can be ported by the customer for even more flow. As requested by previous LSX™ customers, the intake features the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange and o-ring gasket and threaded insert throttle body mounts that provide increased durability.

Now you've gone and gotten AC/DC stuck in my head... thanks.

Guess I'll have to go for a drive.

 

 

Thanks for the quick shipping guys!

 

 

Ordered one by phone last week. Thanks Seth

 

Ordered mine today, woohoo!

 

 

What gains should I expect from the FAST 92 and your 92mm TB on a stock 2002 Z06 with A twin cone intake and BORLA XR-1 exhaust.

 

Going from a LS6 intake and p&p tb (tuned) on my 99 coupe, to a FAST 92 and LS2 picked up 15whp. Should be 15-20whp for you if your car is tuned. If not, probably closer to 25-30whp.

 

I have never had the car tuned. So would you say maybe even more once I install it and then tune? Being the manifold would be off...how much more time would be needed to do a cam change too?

 

Having the intake manifold off won't help with the camshaft labor.

 

Thanks for your orders!
