Skunk2 Ultra Series Valves – Honda K20/K24
Unlock the full potential of your Honda K-Series engine with Skunk2 Ultra Series Valves, the ultimate upgrade for high-performance builds. Engineered for K20 and K24 applications, these one-piece forged valves are crafted from HNV-3 martensitic steel (intake) and EV8 austenitic steel (exhaust)—premium alloys known for their extreme durability, heat resistance, and corrosion protection. Whether you're pushing high RPMs on the track or demanding maximum reliability on the street, Ultra Series Valves are built to outperform and outlast.
Designed for superior airflow and combustion efficiency, these valves feature a Chromium Nitride (CrN) coating applied via a Physical Vapor Deposition (PVD) process, significantly reducing friction and improving wear resistance. The result? Better heat dissipation, longer valve life, and enhanced engine stability under extreme conditions. A proprietary heat-treatment process further strengthens each valve, ensuring consistent performance and reliability even under extreme cylinder pressures.
Key Features:
- One-piece forged construction – Superior strength and longevity
- Chromium Nitride Coating – Reduces friction and enhances durability
- Optimized head profiles – Maximized airflow for improved engine efficiency
- Proprietary heat treatment – Increased hardness and wear resistance
- Lightweight design – Up to 10g lighter than stock, reducing valvetrain mass
Specifications:
- Overall Length (Intake/Exhaust): 109mm / 108.6mm
- Head Diameter (Intake/Exhaust): 35.00mm / 30.00mm
- Stem Thickness (Intake/Exhaust): 5.48mm / 5.45mm
- 16 valves per kit
Tested on the dyno and proven on the road, Skunk2 Ultra Series Valves deliver the performance, reliability, and precision demanded by serious engine builders. Whether you're running all-motor, turbocharged, or supercharged applications, these valves will help your K-Series engine breathe better and rev higher.
