Ferrea VQ35DE Full Valve Train kit - 03-07 Infiniti G35

This valvetrain kit is designed for the person with a serious 2003-2007 Infiniti G35 VQ35DE performance engine build in mind. It features 1mm oversized intake and exhaust valves for increased airflow characteristics. 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. Heavy Duty 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 HD springs.

Kit includes:

12 Intake valves 1 mm Oversize
12 exhaust valves 1 mm Oversize
24 Heavy Duty valve springs
24 Titanium valve spring retainers
24 Spring seat locator's
48 Valve stem keepers
