Manley Mitsubishi Evo X 4B11Y 16pc Titanium Retainers
Retainer angles are held to within 6' (minutes) (this is a tenth of a degree) and installed heights are held to within .005"!
Titanium retainers are a must for your high RPM Sport Compact engine. Their lighter mass allows the tuner to turn higher engine speeds and still avoid dangerous valve float; without sacrificing reliability.
