Tomei VALVE GUIDE SET For SKYLINE GT-R RB26 163046 COMPLETE HEAD EJ20# 02-05 WRX USDM φ93We chose to use Phosphor Bronze (Cn Sn P alloy) to make our Valve Guides, for its highly tensile and superior heat transferring ability, which is vital in high power and high RPM outputting engines. Since race engines these days require more power at higher RPM use , these engines now experience more extreme heat conditions. These conditions will increase the deterioration rate on these valve train related components. The Phosphor Bronze material has
