Description
GrimmSpeed continues its legacy of precision and quality with the FA20 Head Gasket Sets—engineered to deliver unbeatable sealing performance for both naturally aspirated and high-horsepower builds. Designed for FA20F DIT (WRX) and FA20D (BRZ, FRS, 86) engines, these gaskets ensure reliability whether you’re refreshing your engine or pushing a full race setup.
Features:
- Multi-Layer Steel (MLS) Construction: Provides consistent, high-strength sealing across the combustion chamber.
- Folded Stopper Layer: Optimizes combustion chamber sealing to prevent leaks under extreme cylinder pressures.
- Nitrile Rubberized Coating: Reduces risk of leaks on imperfect mating surfaces, accommodating RA finishes up to 50 microinch.
- Multiple Thickness Options: Available in .78mm, 1.05mm, and 1.45mm for precise build tuning.
- Oversized Bore Capacity: Supports up to 86.5mm, allowing up to 0.5mm overbore for custom builds.
- Left and Right Side Specific: Sold as a complete set for full engine coverage.
Tested for Performance:
GrimmSpeed’s innovative design uses strategically undercut middle layers to ensure even crushing and perfect sealing across the combustion chamber. Pressure-sensitive film testing confirms even distribution, keeping combustion gases where they belong—pushing the piston, not escaping past the gasket.
