GSC Power-Division chrome polished intake valves feature 34mm standard diameter for the 4G63T engine in 2005-2006 Mitsubishi Lancer Evolution 9 and 1990-2006 DSM vehicles.

- One-Piece Forged Design: Delivers higher strength over OEM two-piece valves resisting flex and failure at extreme RPM
- 7mm Stem Diameter: Micro-polished stems minimize guide wear and friction for consistent valve action
- 115.44mm Overall Length: Ensures exact stock valve timing lift and clearance in Evo 9 and DSM cylinder heads
