How to Choose the Intake Manifold for 5.3 Vortec?
Well, we saw several aspects and learned about the specialties of these products. However, to figure out what works best for your engine, you need some essential factors. So now, let us discuss these factors that will help you choose.
Before checking any other aspects, the first thing that you need the right fitment. You might find several attractive features in an intake manifold. However, if it doesn’t support your engine, then all your efforts will go in vain. Therefore, make sure that it fits perfectly into your engine.
The RPM range helps you find out the perfect match for your engine. That is why don’t forget to check that range before buying one. If you are looking for options for your street car, 600 RPM will work great for you.
However, performance cars require higher ranges. And so, for that, you might go for the ones starting from 2500 to 8000.
To get the best from your engine, you should always look for better throttle response and idle quality. And so, prioritize the ones with smaller cross-sectioned runners and plenums for your street-cars.
On the other hand, larger plenums and runners can pass a higher amount of fuel. Therefore, look for higher ones if you are working with performance cars.
Intake manifolds have to handle temperature fluctuations. As a result, durable material allows you to get better protection against excessive heat. For that, look for products that include sheet metals or composite metals.
Well, the correct plane system depends on what type of vehicle you are using. For example, if it is for a regular one, you will need a double plane system. Again, single-plane systems work better for performance cars.
