This fabricated aluminum sheet metal intake manifold by Top Street Performance is made to improve the look and performance of your LS3 engine. It features a 102mm throttle body opening for maximum air flow; adapters are available if you're running the factory LS3 throttle body.
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.
