Product Description

The HKS 24999-AH002 Fine Tune Sport timing belt is a reinforced upgrade for Honda's B16A, B16B, and B18C engines, built for drivers who push their car hard on track. Compared to conventional belts, HKS reports heat resistance, tooth-chipping resistance, chip life, and cut resistance averaging 2.3 times higher, giving the belt the strength to hold up under sustained circuit sport driving.

The belt is finished in HKS's signature purple with the logo, product name, and code number printed on the back for easy identification. Because this is a competition-oriented part, the increased belt strength can introduce more drive noise from the tension setting than a stock belt, and the nylon-fiber facing may cause additional cam pulley wear over time, so regular maintenance is recommended. Fitment spans several Honda models sharing these engines - confirm your vehicle uses the 125-tooth spec (rather than the 124-tooth 24999-AH001) using your genuine Honda part number before ordering.
