SHEET METAL LOW PROFILE INTAKE MANIFOLD TIG WELDED ALUMINUM LS3 L92 EFI 102MMOVERVIEWWe 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 3mm 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. QUALITY CONSTRUCTIONThe 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 3mm T-6061 aluminum, which means it can easily handle up to 20 lbs of boost - more than enough for most street performance applications.INTELLIGENT DESIGNIn addition to the premium build quality, our 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. This is the classic, hi-ram design.FITMENTCHEVROLET SMALL BLOCK V8 GEN. III/IV (LS-BASED) 4.8 L / 293 in3 (L20, LY2)5.3 L / 325 in3 (LC9, LH6, LH8, LMG, LY5)6.0 L / 364 in3 (L76, L96, LFA, LY6)6.
