Operation: Intake and exhaust valves: things to know.

In this video, we finally find out why intake valves are slightly larger - about 10/15% - than exhaust valves. Intake valves do not need to be cooled because they draw in air, which naturally cools them. Additionally, the combustion chamber needs to be filled as quickly as possible to increase performance. On the other hand, exhaust valves are smaller due to the need for a tighter seal; being smaller allows for a better seal. Furthermore, being smaller helps dissipate heat more quickly on the valve head.
