Tomei Valve Guide Set 4G63
TOMEI Valve Guide Since Phosphor Bronze (Cn-Sn-P alloy) has intensity and high thermal conductivity it is used for the TOMEI Valve Guides, which support higher engine rotation and higher performance engines. Moreover, since its rubbing characteristic is higher than general material, clearance with valve can be made smaller and attachment of the circumference of valve and operation accuracy can be improved.
