FAST LSXHR 103mm Black Polymer Rectangular Port LS7 Intake Manifold

If you're looking to get the most out of your 2006-2013 Chevrolet Corvette, especially if you're running a boosted or naturally aspirated setup, this FAST LSXHR 103mm intake manifold is a serious contender. It's designed specifically for raised rectangular port LS7 engines and is built to handle significant pressure, rated for up to 45psi. This isn't just about raw numbers; the polymer construction is a key feature that helps keep temperatures down, unlike many aluminum manifolds that can absorb and transfer heat, robbing you of power.

What's really interesting about this manifold is its tunnel ram-style design, which is pretty unique for a polymer piece. It allows for removable stacks of different lengths, so you can actually tune for the specific RPM range where you want maximum power. FAST has seen an average gain of around 30 horsepower between 5,000 and 7,500 RPM compared to other tunnel ram intakes. Plus, the fuel injector angle is set up to optimize spray for better atomization, which means more consistent power and improved drivability. The top of the manifold is reversible, giving you flexibility for throttle body placement, and it even includes bosses for direct port nitrous systems if you're going that route. The 103mm opening can be matched up to 105mm, so it's ready for larger throttle bodies.

When you're installing this, remember that the polymer construction is lightweight and strong, but it also means you'll want to follow the manufacturer's instructions carefully to ensure a proper seal. It's a well-built piece designed for serious performance applications.
