BLOX Racing MLS Exhaust Turbo to Downpipe Gasket - 6 Layers - Subaru EJ20/EJ25
BLOX Racing MLS gaskets deliver a tight seal between turbo and downpipe on Subaru EJ20 and EJ25 engines. This 6-layer design fits Impreza WRX STI Forester XT Legacy GT Outback XT and more from 2002 to 2017. It prevents exhaust leaks to sustain boost pressure and engine power.
Key Features
- 6-Layer MLS Construction: Multiple stainless steel layers with nitrile rubber beading resist extreme heat up to 2000°F and cylinder pressures over 100 psi for long-lasting performance.
- Stainless Steel Core: Corrosion-resistant material maintains shape under thermal cycling and vibration in high-boost turbo setups.
- Precision Port Matching: Exact fit for EJ20/EJ25 exhaust ports eliminates gaps and ensures zero leaks on stock or aftermarket manifolds.
- High-Pressure Seal: Engineered for turbocharged applications to handle 30+ psi boost without blowouts.
- Direct Bolt-On: No modifications needed for Subaru EJ series turbo to downpipe flange sealing.
Product Notes
- Inspect turbo and downpipe flanges for flatness before installation to achieve optimal seal.

Installation Notes
- Professional installation recommended.
- Torque bolts to 18-22 ft-lbs in a crisscross pattern using OEM or Grade 10.9 hardware.
