The Carbon TR Intake Manifold offers ultimate tunnel ram performance for LS and LT1 applications.  The sensuous plenum is constructed from high strength carbon fiber with high temp epoxy for improved strength to weight ratio and reduced heat soak to the fresh air charge. Bonded with high temp aerospace structural adhesive to precisely machined billet, the intake forms a perfect tunnel ram for high power and high revving applications.  Raised bellmouths allow optimum flow development at the runner entrance.  Increased plenum volume helps horsepower and A/F distribution across all cylinders.

What comes with the intake manifold?  Intake Manifold, mounting hardware, throttle seal o-ring, bracket for MAP sensor

What is the lead time?  All carbon intake manifolds are built to order to accommodate choices such as anodize color and carbon finish.  Depending on shop load all intakes take 1- 4 weeks to build.  Periodically we stock popular configurations.

How tall is this?  Various configurations have different heights.  As a general rule all are shorter than the Holley Hi-Ram, but slightly wider.  See dimension pop-ups in the specs above.

Will this fit a Corvette?  This will not fit late model Corvettes and was built for other applications using LS engines such as race cars, hot rods and resto-mods.
