Why This LS6 Intake Manifold Is a Smart Buy
The LS6 Intake Manifold has earned a strong reputation for reliability and performance. Taken from a 2003 Z06 Corvette, this unit is already a step above many factory intakes. Adding billet fuel rails and AN-6 fittings makes it even more attractive for modified builds.
You get a complete package that looks great and performs well. The polished throttle body adds a nice visual touch under the hood, while the billet rails provide modern fuel delivery support. It’s a very nice setup that’s ready to install and start making power right away.
LS6 Intake Manifold – Perfect for Your Next Build
Many people choose the LS6 Intake Manifold when they want better flow without going to a full aftermarket piece. This one comes from a low-mileage or well-cared-for 2003 Z06, so you know it has quality behind it.
The included billet fuel rails and AN-6 fittings make it easy to connect to your fuel system. The stock MAP sensor ensures proper engine management, and the polished throttle body gives your engine bay that clean, custom look.
