Honda R18A Camshaft

Honda R18A Stage 3 High-Angle Camshaft Kit

This E-ROM performance camshaft kit is the most cost-effective power enhancement solution for the R18A engine. With its optimized performance data, complete set of 16 valve springs, and seamless experience brought by intelligent electronic control, it resolves the contradiction between performance and daily use, rejuvenating your beloved car.
This product’s data has been precisely optimized based on the hardware characteristics of the R18A engine. It significantly enhances the power while ensuring stability and reliability.

R18A Stage3 Intake Camshaft (IN) Data (with i-VTEC activated):
· Valve opening duration (Adv.Dur.): 292 °
· Valve lift: 11.25 mm
R18A Stage3 Exhaust Camshaft (EX) Data (with i-VTEC activated):
· Valve opening duration (Adv.Dur.): 293 °
· Valve lift: 11.20 mm

The continuous angle of nearly 290 degrees and a valve lift of over 11mm have significantly increased the valve opening time and opening degree for the R18A, effectively enhancing the volumetric efficiency at high RPMs. This is a solution suitable for racing vehicles. Currently, we have manufactured the Mainline with 165 horsepower at the wheels.

Essential reinforcement components: The original factory valve springs cannot withstand the additional pressure caused by high lift for an extended period. To ensure absolute safety and complete performance release, upgrading the valve springs is absolutely necessary.

· High-performance valve springs (Valve Springs): 16 pieces
· Precise matching: Specifically designed for a 11.25mm lift, providing constant and sufficient clamping force.
· High-speed stability: Made of high-quality materials, with strong fatigue resistance, ensuring that the valves can close promptly and accurately at high speeds, preventing “float” phenomena and protecting the safety of your engine.
