Upgrade your Audi R8 5.2L V10 or Lamborghini Huracán 5.2L V10 with GSC Power Division Super Alloy Performance Exhaust Valves, built for superior airflow, efficiency, and durability in turbocharged and naturally aspirated engines.

The back cut design improves airflow, increasing power output and RPM potential. Micro-polished valve stems reduce friction and oil retention, ensuring smoother operation and longer component life, even at high RPMs.

Crafted from super alloy materials, these valves withstand the extreme heat and stress of turbo and supercharged engines. Hardened valve tips ensure extended durability and optimal contact with the rocker or valve tappet.

Designed for OEM replacement, these valves fit seamlessly with OEM keeper/lock systems. GSC Power Division recommends using new valve locks in performance setups to avoid material grooving.
