Supertech MINI B48 Inlet and Exhaust Valve Guides
These Supertech valve guides are precision machined and designed to be used alongside Supertech valves for high horsepower applications. Designed to draw away heat from the valve itself, these valves are a great option when building your MINI B48 Cooper S or JCW engine.
Exhaust guides use a copper alloy guide. Copper has about a 3 times higher thermal transfer than Manganese Bronze which is used for the Inlet.
They are required when installing Supertech performance inlet and/or exhaust valves. They are not required for all rebuilds just when you change the OE valves.
