How to choose and what to check
When choosing an aftermarket replacement, compare the inner and outer diameter, thickness and profile of the ring with the original; among the available replacements listed in the catalog are Febest TCP-003, MasterKit 77BGB074, PATRON PG1-6105, LUZAR LES21915, MAXGEAR 700440. The ring is replaced when there is an oil leak into the spark plug well, the spark plug is oil-fouled, or after removing the valve cover if the old part has hardened or lost its elasticity. Check compatibility by body and engine number, not just by model.
