Intake and Exhaust Valves: Things to Know

Model: (Various brands) Various
Part: Valve

Video tutorial

In this video, we finally learn why the intake valves are slightly larger - about 10 to 15% - than the exhaust valves. The intake valves do not need to be cooled, as they draw in air, which cools them naturally.

Furthermore, being smaller, they dissipate heat more quickly onto the head itself.
