​The HKS 22002-AT004 is an intake camshaft designed for the Toyota 2JZ-GTE engine equipped with Variable Valve Timing with intelligence (VVT-i). This high-performance camshaft aims to enhance engine efficiency by optimizing valve timing, making it suitable for motorsport and high-performance applications.

Product Features:

• This camshaft offers increased valve lift and valve timing compared to the standard camshaft, improving engine output by enabling greater intake and exhaust gas flow.
• It is compatible with the VVT-i (Variable Valve Timing-intelligent system), optimizing torque across a wide engine RPM range, which enhances turbo response.
• The camshaft timing can be adjusted using the HKS Valvetiming Controller (VTC), improving the response compared to the factory system.
• The product is designed for use in closed-circuit motorsport environments.
