Single Beehive Valve Spring Set w/ Titanium Retainers Subaru Models | inc. 2002-2014 WRX / 2004+ STI

The GSC Power-Division Beehive Valve Spring Kit with Ti Retainer for the DOHC Subaru Turbo EJ Platforms includes 16 titanium retainers and 16 beehive valve springs. Our beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.

• Max RPM: 8,500 RPM
• Max boost: 35 psi
