Selecting the correct intake manifold for your engine can often be a confusing process. In this guide, I will try to walk you through everything you need to consider to select the right intake for your vehicle.

The first, and most important, thing you need to consider is how you will use your vehicle. The biggest mistake people make when selecting their intake is buying one designed for racing, when the closest they ever come to a race track is beating the idiot in the honda off the line at the stoplight.

Next, you need to consider the RPM range that your engine will typically operate in. This is affected by both the performance parts that have been added and the displacement of the engine.

If you are building a mild street performance engine a low-rise, dual-plane intake will give you greatly improved torque from off-idle through midrange. They also give excellant throttle response. These intakes are ideal for passenger cars, pickups, tow vehicles, and RV's. These intakes make power from idle to around 5500 rpm.

If you are building a hot street performance engine a high-rise, dual-plane intake will give you the best performance. These intakes are designed to build incredible top end power while still delivering satifactory throttle response. These should be used on vehicles with headers, high-lift camshafts, and other modifications. They make power from about 1500 to 6500 rpm.

Low-rise, single-plane intakes are built for high-performance street engines with limited hood clearance. They provide even more top-end horsepower (as compared to a high-rise dual-plane design) while retaining some throttle response. These intakes make power from approximately 2500 to 6500 rpm.

Single-plane, high-rise intakes provide maximum power at high rpm, while sacrificing throttle response and off-idle driveability. The rpm range for these intakes is around 3500 to 8500+ rpm.

There are several other specialty intake designes made for specific applications such as tunnel ram, cross-ram, dual four barrel, and three two barrel designs (along with others). These intakes require specific parts combinations to work correctly. You should work closely with your engine builder to get these combinations to make ideal power.
