Cobb Subaru EJ TGV Shaft Seal Kit 2002-2021 WRX STI Forester XT Legacy GT

The Cobb Subaru EJ TGV Shaft Seal Kit replaces factory seals on Tumbler Generator Valve shafts to stop boost leaks and maintain turbo pressure. Designed for 2002-2021 Subaru models with EJ20 and EJ25 turbo engines including WRX, STI, Forester XT, and Legacy GT. Delivers reliable sealing for consistent power delivery and throttle response during spirited driving.

Key Features

  • Double-Lip Seal Design: Provides two sealing points per shaft for complete prevention of air leaks under high boost conditions.
  • High-Temperature Viton Material: Resists heat up to 400°F and oils, outlasting OEM rubber seals that degrade over time.
  • Direct OEM Replacement: Matches factory dimensions for plug-and-play fit without modifications or special tools.
  • Four Seals Included: Complete kit covers both TGV shafts with left and right specific seals for precise installation.
  • Boost Leak Prevention: Eliminates common failure point causing power loss, check engine lights, and reduced spool time.

Product Notes

  • Inspect TGV shafts for wear during installation; replace if scored.
  • Use fresh intake manifold gaskets when servicing to ensure full seal integrity.
  • Small lightweight part ships in protective poly bag inside padded envelope.

Installation Notes

  • Professional installation recommended.
  • Remove upper intake manifold to access TGV shafts; no manifold disassembly required.
  • Compatible with stock hardware and aftermarket TGV deletes with shaft retainment.
