Using Subaru Genuine parts or a QUALITY aftermarket is very important with all repairs or service work done to your Subaru. We have seen “cheap” timing belts break at 30k miles (which is only half of its normal length). It can cause your valves to get damaged and possibly even require an engine replacement. Cheaper, after market parts are not as high of quality as those offered by SOA and other manufactures, and in many cases are inferior in design, proper fit, performance, and ultimately, longevity. You could save a few bucks up front, but in the end when the car breaks down without warning, you have to have it towed and/or replace the part(s) more often, you end up spending more in the long run.
