Using these JE pistons and rings is straightforward. First, make sure your engine is the SUBARU EJ25 DOHC from 1997 - 1999 as specified. Check the bore size to be 99.5mm and the deck clearance to be '0'. When installing, there's no need to deburr the dome or dish as they're ready - to - use. The pistons are made of high - quality 2618 T6 forged aluminum, so handle them with care. Don't forget to use the provided straight - wall carbon steel wrist pin and the included pin fitting and Tru - Arc locks. For maintenance, regularly check the rings and pistons for wear. If you notice any unusual noise or performance drop, it might be time to inspect them more closely. Keep the engine clean and use the right oil to ensure a long lifespan for these components.
