Subaru Technica International’s timing belt is actually very similar to the timing belt that is used on the Subaru WRC Rally Cars.  It is designed specifically for the higher demands of hard driving, using Kevlar fibers for reinforcement, making it significantly more durable than the OEM belt.  You may notice an increase in belt noise when using this part.

Subaru recommends that you change your timing belt every 62,500 miles.
