GSC P-D Mitsubishi Evo 9 4G63T 34mm Dia (STD) Chrome Polished Intake Valve - Set of 8 (1990-2006 DSM & Evo)

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. This set of 8 delivers direct replacement with one-piece forged strength to handle high-boost and high-RPM demands. Install during cylinder head work to gain better airflow and reliable power.

Key Features

  • 34mm Head Diameter (STD): Matches OEM specs for plug-and-play fit in stock valve seats on 4G63 heads
  • Chrome Polished Finish: Bead blasted then chrome coated to boost heat transfer from valve head to seat reducing thermal fatigue
  • 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

Product Notes

  • MPN 2002-8 designed for intake side only requires matching exhaust valves for full valvetrain upgrade
  • Inspect valve springs and retainers during install for compatibility with performance cams
  • Packed in protective sleeves to prevent damage during transit

Installation Notes

  • Professional installation recommended.
  • Cut valve seats to 45/30/60 degree three-angle for optimal sealing and flow
  • Works with OEM retainers springs and locks no special hardware needed
