We have also included the crankshaft seal, camshaft seals, AVCS intake sprocket plate O-rings, AVCS exhaust sprocket plate O-rings, and a replacement AVCS oil feed line filtered fitting. Subarus are renowned for their durability, and a Subaru with 105,000 miles still has plenty of life ahead! To ensure your car continues to perform optimally, it's advised by Subaru to perform a 105,000-mile service once your vehicle reaches this mileage. To maintain the longevity of your engine, it’s important to take care of the water pump and timing components on or before the recommended mileage. This service includes the timing belt, thermostat, accessory belts, idlers and water pump. The IAG 105k Service Package offers an easy solution for obtaining all the essential parts needed for your timing and water pump service - all in one convenient bundle. Our 105k Service Package includes the crankshaft seal, camshaft seals, AVCS intake sprocket plate O-rings, AVCS exhaust sprocket plate O-rings, and a replacement AVCS oil feed line filtered fitting. The fitting can only be reached with the removal of several timing components, so it’s an opportune time to inspect and replace the fitting while you have easy access. IAG’s 105k Service Package gives you the option to replace all recommended maintenance components along with these commonly worn parts in one complete service, saving you time and money.
