The Right Fit: Choosing an Intake Manifold Cover
A carburetor makes engine combustion possible, and for the past century, this principle has remained unchanged. Any car owner would like to protect the engine's intake from any foreign particles that can contaminate the inner workings of your engine. If you are planning to change your engine's intake manifold cover, check out this guide before making your choice. It's a must for anyone who wants to keep their engine clean.
Types of Intake Manifolds
Before picking the right intake manifold cover, you have to know the type of intake manifold your vehicle has. Listed below are the different types of manifolds:
- Dual intake and single intake manifolds differ only in that the former has a divider running down the middle of the manifold itself. These manifolds have wide gaping openings.
- Square bore intakes have four openings or "venturis" of equal size that are evenly spaced in a co-parallel fashion.
- Spread bore intakes are oddly shaped and have two smaller openings with two larger openings in front. The opening itself is not balanced out with one side wider.
- Tunnel rams are the rarest of the lot and accommodate two 4-barrel carburetors in one. These are made for high RPM and large horsepower output applications.
Knowing your vehicle's carburetor type is important, and the best reference is your vehicle owner's manual. It will determine the size and shape of the cover that you are planning to purchase.
Choose Your Materials Wisely
Be careful when you're shopping for an intake manifold cover, because some unscrupulous manufacturers try to pass sheet metals as a cheap alternative. Sheet metal is very flimsy and it's prone to heat damage. It may be cheaper but it may cause damage to your engine in the long run. Aluminum on the other hand, is extremely heat-resistant and corrosion-resistant as well. True, you have to pay a premium price for aluminum, but this is your engine after all.
