Using these JE pistons and rings is straightforward. First, make sure your Subaru EJ25 SOHC engine is from 1999 or later and that the bore size is 99.5mm. Install the pistons and rings carefully, following the engine's assembly guide. Since the dome/dish doesn't need deburring, you can save time on preparation. When it comes to maintenance, keep an eye on the engine's performance. Regularly check the ring widths and the condition of the wrist pin. If you notice any unusual noises or a drop in performance, it might be time to inspect the pistons and rings. Also, make sure to use the right lubricants to keep everything running smoothly. Remember, these are high - performance parts, so treat them with care for long - lasting use.
