HKS 2003-2005 Nissan 350Z Infiniti G35 VQ35DE 0.7mm Stopper Head Gasket (97mm Bore/10.3 CR)

This HKS stopper head gasket equips 2003-2005 Nissan 350Z and Infiniti G35 models with the VQ35DE engine for demanding performance applications. The 0.7mm thickness and 97mm bore support 10.3:1 compression ratios in boosted or naturally aspirated high compression setups. It ensures a tight seal under extreme cylinder pressures and temperatures for consistent power delivery.

  • 97mm Bore Clearance: Accommodates oversized bores up to 97mm supports stroker kits and big bore builds without interference
  • Multi-Layer Steel Design: Vermiculite-coated stainless foil layers provide exceptional heat resistance and recovery for repeated heat cycles
  • Direct OEM Fitment: Matches factory bolt patterns and dimensions for straightforward replacement in VQ35DE cylinder heads

Product Notes

  • Inspect piston-to-valve clearance after installation to ensure safe operation
