Technical Description

Stop the "Blue Smoke at Idle" and protect your K0422 seals. The 2.3L DISI engine produces high oil pressure that often overwhelms the factory K0422 turbo seals, especially after installing a high-flow downpipe. Without proper regulation, machine oil is forced into the exhaust, creating the dreaded blue smoke at stoplights. This GryphonTek Signature Series Fitting is the professional-grade solution, featuring a built-in 1.8mm restrictor to manage oil flow and safeguard your turbo’s longevity.

  • 1.8mm Precision Restrictor: Regulates oil flow at the source to protect sensitive K0422 internal seals from over-pressurization and blow-by.
  • -4AN Conversion Foundation: Replaces the stock setup with a secure -4AN flare, allowing for a leak-free transition to high-performance braided PTFE oil lines.
  • Industrial-Grade Durability: Machined from high-strength mild steel with corrosion-resistant electroplating to survive extreme "Hot Side" radiant heat.
  • Professional Sealing Integrity: Includes high-purity annealed copper washers to ensure a permanent, zero-leak interface even under high-boost engine harmonics.
