Intake Manifolds
The intake manifold is the last, and arguably the most important, part of your engine's air intake tract. It's here where the air or air/fuel mixture that exits the throttle body or carburetor respectively is distributed to each individual cylinder head intake port. How well the intake flows and how evenly the air or air and fuel is allocated is critical to your engine's power output and your vehicle's performance.

There are several reasons for dumping your factory intake for an aftermarket manifold: The runner shape on even performance models will generally not be as advanced as the latest aftermarket manifolds; The OE manifold may be constructed from heavy cast iron; if you have a V-type engine you may be able to get by without a heat crossover passage; and finally, the factory manifold's configuration may be unsuited to the rest of your engine modifications.
Even the best OE manifolds are a compromised result of drivability, emissions, underhood clearance, and above all cost considerations. Couple that with production line tolerances and you end up with a manifold with less than ideal runner bends and contours, and poor air flow and dispersion. By switching to a state-of-the-art, lightweight, aluminum, performance manifold you'll see an increase in horsepower and torque, and if you live in a warm climate and can do without the heat crossover, the cooler air/fuel mixture will increase power even further.
An aftermarket performance intake manifold will help you get the most from your engine no matter the size or how it's configured. Whether you have an in-line 4 or V8, torque monster or screaming high revver, we have the manifold to suit your needs. Factory manifolds were designed to work with the OE level of tune, with runners that are often narrow to keep velocity high at low rpm. But if you've changed the cam and cylinder heads, and carburetor or fuel injectors, you may want to make horsepower significantly higher up the rev band and that factory manifold's not going to cut it.
For in-line 4 cylinder engines we have large runner, high velocity intake manifolds for making high rpm horsepower. For V8 engines we have dual plane single 4-barrel intakes that make power from off idle to 5500 rpm, as well as single plane manifolds for revving to 8500 rpm and beyond. For hot rodders that crave the looks and performance of multiple carburetors we have dual quad and tri-power setups, and for the ultimate performance statement, single and dual quad tunnel rams. Along with our manifolds, we have performance gaskets and mounting bolt kits, so you can get everything needed for installation right here.
Or why not go all the way and upgrade your entire induction system with a manifold and carb kit. You get a carburetor and intake manifold that have been engineered to work together for optimal performance, in your choice of satin or chrome-like finish, and the kit comes complete with intake gaskets, intake bolts, and carb studs. Choose from single 4-barrel, dual quads, and vintage kits with multiple carbs, including two, three, and six 2-barrel setups. Vintage kits are perfect for street rods and come with straight or progressive throttle linkage, gaskets, bolts and carb studs. To complete the classic look, install your intake and carbs with a polished aluminum fuel distribution block or fuel log kit.
