Is an aftermarket intake worth it?

Compared to hot air, cold air allows more fuel to burn more efficiently, due to the increased rate of oxygen combustion. Because of this, installing a cold air intake kit may result in increased horsepower.

Does an air intake make a difference?

The good news is that although claims of actual horsepower and even increased fuel efficiency may vary, cold air intakes will in fact help increase your car's performance. But if you team up the cold air intake with other engine modifications, like a new exhaust, you'll create a much more efficient system.

How much horsepower does a cold air intake add to a v6?
