Product Description

The HKS 24999-AH001 Fine Tune Timing Belt is a performance-oriented timing belt engineered specifically for Honda B16A-equipped vehicles such as Civic (EF9, EG6, EK4), CR-X (EE8), Del Sol (EG2), and Integra (DA6/DA8) from late 1980s through 2000. Designed for circuit-sport driving and high-RPM use, the Fine Tune belt uses a high-strength, aramid-reinforced H-NBR compound and molded-tooth construction to significantly increase durability and resistance to tooth chipping, wear, and thermal degradation compared to standard OEM belts. This makes it ideal for enthusiasts running tuned or high-stress engines, or drivers who demand higher reliability under aggressive driving conditions.

Because the belt retains the correct tooth count and tension specs for B16A engines, installation is straightforward on compatible vehicles - no modifications required. However, due to the enhanced stiffness and tension inherent in this performance belt, regular inspection is recommended, and belt tension should be checked carefully after installation. The HKS Fine Tune Timing Belt offers a strong, reliable upgrade over stock belts - especially for high-RPM driving, track use, or modified engines where OEM belt life may be insufficient.
