Supplier's note

  1. Technical Breakthroughs:

    • Material Composition: The Pro Model’s 2.5mm rubber compound outperforms industry standards by withstanding 220°C, enabling safe operation in turbocharged engines.
    • Precision Engineering: The Advanced Model’s 200°C tolerance and 4.0 bar pressure resistance align with Subaru’s OE specifications for high-performance models like the WRX STi.
    • Universal Fitment: The Base Model’s OEM dimensions ensure direct compatibility with 13270AA190/13272AA140 applications, reducing installation errors.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard Subaru turbo engines (e.g., Outback 2.5i) requiring reliable sealing without extreme conditions.
    • Advanced Model: Recommended for high-output turbo setups (e.g., Legacy GT, Impreza WRX) needing enhanced pressure and heat resistance.
    • Pro Model: Best for track or modified vehicles (e.g., WRX STi) where prolonged exposure to extreme temperatures and pressures is expected.

With the Pro Model’s 220°C tolerance, you can safely handle aggressive turbocharging. Pair its 2.5mm thickness with Subaru’s EJ255 engine for a seal that lasts under continuous high-load scenarios.
