GSC Power Division Intake Valve – Single Audi R8 5.2L V10 / Lamborghini Huracán 5.2L V10 - GSC2252-10
Upgrade your Audi R8 or Lamborghini Huracán 5.2L V10 engine with GSC Power Division’s high-performance stainless steel intake valves. Built for enhanced airflow, durability, and efficiency, these valves deliver measurable gains whether your setup is naturally aspirated, turbocharged, or supercharged.
Engineered with a back-cut profile to promote smoother airflow, these valves help unlock higher RPM capability and improved horsepower. The micro-polished stems reduce friction and oil buildup, supporting cleaner valve movement and longer service life—even under extreme RPM conditions.
Crafted from premium 21-4 stainless steel, they’re designed to endure the intense heat and pressure of forced induction environments. Hardened tips ensure lasting contact with rocker arms, minimizing wear over time.
These valves are a direct-fit OEM replacement and are fully compatible with factory keeper/lock systems. For high-output builds, GSC recommends installing new valve locks to avoid potential grooving from reused components.
