Cold Air Intake

A cold air intake is an aftermarket intake system that draws cooler air from outside the hot engine bay, often with a cone filter.

What is Cold Air Intake?

Cooler, denser air contains more oxygen. Real power gains on modern engines are usually small. Many systems make the intake sound louder. Factory airboxes are often already designed to draw cool air from outside the engine bay.

How it works

Moving the filter away from engine heat lowers the intake air temperature, which can slightly improve combustion.

Why it matters for your car

A badly placed filter can suck in water in heavy rain or deep puddles. Oiled filters can contaminate the mass air flow sensor if over-oiled.
