You’re considering installing a high flow intake manifold on your car, but you’re curious as to what part of your engine’s performance it will help with. Your engine is basically nothing more than a somewhat sophisticated air pump. The more air you flow through it, the more work you can get out of it. That high flow air intake is a good start. If the intake is properly tuned, you will see gains across the whole power band, acceleration included. Adding headers and a free flowing exhaust will help you realize even larger gains in acceleration, mid-range and top end power.
