Supertech Inconel Exhaust Valves (Set of 8) – Subaru FA20 / Toyota 86 / BRZ / FR-S
Fits: Subaru FA20 engines – Toyota 86 / GT86 (ZN6, 2012–2021), Subaru BRZ (ZC6, 2012–2020) and Scion FR-S. Standard head size. Fitment on the FA24 (GR86 / 2022+ BRZ) isn't confirmed, so contact us before ordering for those.
Supertech Inconel exhaust valves are made for extreme heat. Inconel holds its strength at the high exhaust temperatures seen in turbo and high-boost FA20 builds, where a factory valve is at risk. A common upgrade during a head rebuild alongside upgraded springs and guides.

FAQ
Why Inconel for the exhaust side?
Exhaust valves run much hotter than intakes, especially on boost. Inconel keeps its strength at high temperatures.
Are these standard size?
Yes. They have a standard 29mm head, so they suit a standard head without oversize seat work.
Do I need new guides and springs?
On a head rebuild it's recommended. See the GSC guides and spring kit linked above.
