Etuners Forged Pistons are engineered for maximum reliability and outstanding performance. Crafted from the premium 4032 aluminum alloy, these pistons offer high silicon content to minimize expansion under extreme temperatures. Whether for street use or competitive motorsport, Etuners pistons deliver strength, durability, and efficiency, making them the perfect choice for high-performance engines.
Key Advantages of Etuners Forged Pistons
Premium 4032 Alloy Composition: High silicon content reduces thermal expansion, ensuring tighter tolerances between the piston and cylinder wall. This improves performance and engine lifespan under extreme conditions.
Two Versions Available:
- Street Version: Designed for everyday comfort and light motorsport, these pistons maintain standard gaps for reduced cold-start noise and smooth operation in city driving.
- Race Version: Features full phosphate coating for enhanced oil adhesion, protecting the piston and cylinder wall during high temperatures and at engine speeds exceeding 8500 RPM. With excellent anti-knock properties, these pistons are capable of handling over 250 HP per cylinder.
High-Precision Manufacturing: CNC-machined to a tolerance of 0.0002, ensuring weight balance within ±1 gram and superior performance consistency.
Anti-Knock and High-RPM Resilience: Both versions provide excellent anti-knock properties, ensuring stable performance even under heavy loads and high engine speeds.
Customizable Clearance Settings: Recommended piston-to-cylinder wall and ring end gaps are optimized for different use cases, from street driving to high-performance turbocharged engines.
