HKS Fine Tune Timing Belt 2002-2014 WRX / 2004-2021 STI / 2005-2012 Legacy GT / 2004-2013 Forester XT

HKS has engineered this timing belt to optimized specifications specifically for the Subaru boxer engine, which features a long belt designed to work with the stock EJ engine belt tensioner. This timing belt is developed with thermal expansion of the engine block and head in mind, ensuring proper valve timing and maintaining correct belt tension under all operating conditions.

The belt incorporates a new tooth design that fits fully into the cam gears, and it is constructed from high-saturation H-NBR (Hydrogenated Nitrile Butadiene Rubber) for increased strength and durability. Compared to a stock belt, this HKS timing belt resists stretching and warping, helping your Subaru maintain precise engine timing for reliable performance.
