  • Q: Ring gap?   Allen Lish4 years ago

    Will these rings already be gapped to proper size for an EJ25 engine?
  • Q: ej251  elizondj55 years ago

    Can these rings work on the ej251 motor?

      A:  These rings will fit 99.5mm Cosworth pistons for Subaru 2.5L engines. There should be no problem using the pistons and rings on the EJ251 engine, but we cannot guarantee fitment because Cosworth does not.
