TSP Velocity LS1/LS2/LS6 102Mm Fab/Alum Low Profile Intake Manifold #81001CA

We designed our fabricated aluminum sheet metal intake manifold to improve the look and performance of your LS engine. It features a 102mm throttle body opening for maximum air flow. The runners are velocity stacked, allowing air to move more smoothly at high velocities. The manifold is constructed of 3.5mm thick T-6061 aluminum and is TIG welded to ensure consistent strength and performance. Individual port o-rings guarantee a good seal with the cylinder heads and throttle body. Available in clear or black anodized finishes, this manifold will also give your engine bay a nice, clean aesthetic.

The first thing people notice when taking a closer at our intake manifold is the beautiful TIG (tungsten inert gas) welding throughout - all done by hand. This ensures solid construction that won't fail under stress. The head flanges are 7/16" thick, and the plenum is constructed of 3.5mm T-6061 aluminum, which means it can easily handle up to 25 lbs of boost - more than enough for most street performance applications.
