Product Description

The HKS 4502-RA002 Type I Speed Limit Defencer is engineered to bypass the factory-set speed limiter in manual-transmission performance cars. Ideal for track-focused drivers, this device sends a signal to fool the ECU, allowing the vehicle to reach higher top speeds safely and reliably.

Plug-and-play installation and durable construction make it ideal for cars like the Integra, S2000, NSX, Accord auto variants, and Lexus IS/SC300 models. As a Type I model, it's tailored for manual gearboxes. It works seamlessly with stock ECU electronics without requiring an ECU reflash. MSRP is $145, often available around $139. Always avoid use in CARB-controlled regions.

Recommended for serious drivers who want to unleash full vehicle potential on track days or sanctioned events. Ensure your transmission is well-maintained before installing a speed limiter remover, and always build responsibly.
