MINI PERFORMANCE & TUNING ENGINES & COMPONENTS - VALVES
Our competition valves are produced in EN214N steel and require installation with bronze valve guides (TMG10819). They are single groove collets (88G459). Rimflow valves are considered to be the best valves on the market. Rimflow valves are produced in EN214N steel but have chromed plated stems to enable them to be installed with iron guides although we recommend bronze guides as these help with heat dissipation. Rimflow valves use single groove collets (88G459).
