Between the cylinder head and rocker cover on all EJ20 & EJ25 engines is where you will find half moon seals.

These are common parts to replace, especially when changing the rocker cover gasket. The original Subaru seals are produced from plastic and have a tendency to leak due to their brittle nature.

Our FUJI Racing Half Moon Seal kit is produced from T6061 Alloy and offers a snug fit, providing a long-term leak-free solution.

Upgrade replacement for Genuine Subaru Plug Cyl-Head 11051AA070 & 11051AA40
Equivalent product for RCM2728, RCM2616 & IAG-ENG-2000


Suitable for the following models:

  • All EJ Engines

If you are unsure of fitment or application then please contact us with your vehicle's chassis number.


  • 4 x T6061 Half Moon Seals
