1962-2021 Chevrolet Velocity Series LS1/LS2/LS6 Hi Ram Intake Manifold, Black Anodized, 102MM 81002TBK

Top Street Performance designed their fabricated aluminum sheet metal intake manifold to improve the look and performance of your LS powered Chevrolet. 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. The first thing people notice when taking a closer at these 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, these fabricated manifold include 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. A recent improvement places a MAP sensor bung on the rear of the manifold.Features and Specifications:Injection Style:Multi-portFuel Rail Type:Custom TSP DesignFuel Rails Included:NoThrottle Body Bore Size:102mmThrottle Body Bolt Pattern:Standard OE 4-Bolt PatternThrottle Body Flange Angle:0°Throttle Body Included:NoFlange Material:T-6061 Billet AluminumPlenum Thickness:3.5mmPlenum Material:T-6061 Sheet AluminumVacuum Ports:NPT 1/8 x 3 and NPT 1/4 x 1Map Sensor Bung:Yes (Sensor not included)Overall Height:9"Included:Port O-Rings and Hardware
