This translates into more power as the engine can breathe easier when RPM and airflow demands increase. Exhaust valves are made from a high-nickel content superalloy to resist the extreme temperatures associated with a high performance turbocharged engine, and intake valves are constructed from stainless steel.


Dual-coil springs are used to increase spring load on the valve in order to prevent valve float at high RPM as well as provide a good leak-free seal for high-boost applications. Titanium retainers are significantly lighter than the steel OEM retainers which translate into less reciprocating mass and lowers the chance of valve-float. Spring seat locators are provided with the kit to enable proper installation of the dual-coil spring.


Kit includes:


* 12 Intake valves, stock size or 1 mm Oversize
* 12 exhaust valves, stock size or 1 mm Oversize
* 24 Dual coil valve springs (inner and outer springs)
* 24 Titanium valve spring retainers
* 24 Spring seat locators
* 48 Valve stem keepers
