HKS SMG/K FA20 t=0.7 Head Gasket 2013-2024 Subaru BRZ Scion FR-S Toyota 86 GR86
The HKS SMG/K FA20 t=0.7 is a multi-layer steel head gasket engineered for FA20 engines in Subaru BRZ Scion FR-S and Toyota 86 GR86 models. Its 0.7mm thickness reduces combustion chamber volume to raise compression ratios for increased power output. This gasket delivers reliable sealing in naturally aspirated and boosted setups handling extreme heat and cylinder pressures.
Key Features
- 0.7mm Thickness: Compresses engine displacement less than stock 1.0mm gaskets to deliver higher compression and power gains in performance builds
- Multi-Layer Steel Construction: Three stainless steel layers with elastomer coating provide durable sealing against high boost levels over 30 psi and temperatures exceeding 1000 degrees C
- 86mm Bore Matching: Precisely sized for FA20 cylinders to prevent blowout and maintain even clamping force across the deck surface
- High-Pressure Resistance: Engineered to withstand detonation and pressure spikes common in tuned FA20 engines with cams pistons or turbochargers
- Direct Fit Design: Matches OEM bolt patterns and dimensions for straightforward replacement without machining or modifications
Product Notes
- Confirm piston-to-valve clearance before installation due to reduced gasket thickness
- Pair with ARP head studs for optimal clamping in high-boost applications
- Handle carefully to avoid creasing the sealing layers during transport
Installation Notes
- Professional installation recommended.
- Torque head bolts to HKS specifications in sequence using moly paste on threads
- Requires new OEM or ARP head bolts. reuse of old bolts not advised
