Choosing the Right Intake Manifold for Your Engine
An appropriately designed manifold can do wonders for your car engine's performance. However, choosing the right one for your ride can get tricky, what with all the types sold in the market these days. Read on to know more about the common types of intake manifold according to layout, height, material, and built as well as the applications that best suit each design:
Layout: Single or dual plane?
A single plane manifold basically has one hole in the plenum. It offers less restriction for the air flow and has a power range of 3000 to 8000 RPM. This type is best suited for race cars.
A dual plane has a split plenum opening and has a wider power range which starts at 1500 RPM. It's best used on an engine used for mild racing and street racing.
Height: Low rise, high rise, or tunnel ram?
Basically, a low rise intake manifold fits better under the hood, while a high rise type may require adjustments to fit. Compared to a low rise, a high rise manifold offers more horsepower and is suited for a higher RPM range and wider power band.
A tunnel ram is a more extreme version of a high rise manifold. This type is designed for engines that require high RPMs and plenty of horsepower. It's best suited for professional car racing engines.
Material: Plastic or aluminum?
Many cars today use a plastic manifold because this type is lightweight and can be easily cast for better airflow. However, it'll easily break if the engine backfires. As for aluminum, it's definitely heavier than plastic but it's more durable. It can also be easily polished, coated, plated, and modified according to specific needs. For heavy-duty use and longer-lasting performance, it's best to go for an aluminum intake manifold.
Built: Custom or cast?
A customized intake manifold can be molded from billet aluminum or hand-built using an aluminum sheet. Whichever the case, a custom-designed manifold can cost thousands of dollars. If you're a serious racer looking for extra horsepower, investing in a customized manifold is a good choice.
If you're a regular Joe looking for a simple replacement, then go for a mass-produced manifold that's more budget-friendly. When it comes to durability, many brands today offer affordable cast manifolds that won't easily give in to wear and tear.
When shopping for an intake manifold, don't forget to take note of your car engine's part number and design as these factors can also affect the type of manifold that'll fit just right. It's also best to do some research first on the most popular brands that offer high-quality manifolds. By arming yourself with the right information, you should be able to choose the right intake manifold without too much of a hassle.
