This fabricated aluminum sheet metal intake manifold has been designed 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 this 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.
In addition to the premium build quality, this fabricated manifold includes intelligent design features that set it apart from the rest. A 102mm throttle body opening and velocity-stacked intake runners guarantee maximum airflow for high-horsepower applications, and individual port o-rings ensure a tight seal to your cylinder heads. Recent improvements include a reduced height and angled throttle body opening for clearance, as well as a MAP sensor bung on the rear of the manifold.
