Industry Standard Exhaust Valves | Everyday road use, stock engines | - Steel alloy construction - 40 dB(A) noise level (ISO 3744) - 200°C max temp (ASTM E1461) | Cost-effective, widely compatible with standard engines. | Limited corrosion resistance (ASTM B117: 500 hours) Lower durability under extreme conditions. |
SUPERTECH Base Valve Springs | Mild tuning, track days | - Chrome-molybdenum steel - 38 dB(A) noise (▲1dB quieter) - 300°C max temp (▲▲) - 1500 RPM stability (SAE J183) | Improved heat resistance vs. standard; affordable upgrade for light use. | No corrosion coating (ASTM B117: 600 hours) Not race-certified. |
SUPERTECH Advanced Valve Springs | Professional racing, high-RPM engines | - Titanium-coated alloy - 35 dB(A) noise (▲▲2dB) - 450°C max temp (▲▲▲) - 7500 RPM stability (▲▲▲) | Ultimate performance for extreme conditions; lightweight for faster response. | Higher cost Requires specialized installation. |
Customizable Competition Valves | Custom engine builds, motorsports | - Modular design (ISO 5817) - 400+ heat cycles (ASTM E228) - 2mm thickness tolerance (ISO 14256) | Tailored to specific engine specs; durable for repeated stress. | Longer lead times Less universal compatibility. |
Lightweight Aluminum Valves | Fuel-efficient engines, hybrid vehicles | - 7075-T6 aluminum alloy - 180g weight (▲▲ lighter) - 250°C max temp (ASTM E1461) | Reduces engine inertia for better fuel efficiency. | Lower heat tolerance vs. steel Not suitable for high-boost applications. |
Corrosion-Resistant Marine Valves | Marine engines, saltwater environments | - Stainless steel 316 (ASTM A276) - 1200+ salt spray hours (ASTM B117) - 280°C max temp | Superior corrosion resistance for harsh marine conditions. | Heavier than aluminum/steel Lower RPM tolerance (▲▲ down). |
