King Engine Bearings, a leader in automotive, aviation and high performance engine bearings, will introduce its new Subaru XPG bearings at the 2012 PRI and IMIS shows. King's new bearings are specifically engineered to solve premature bearing failure caused by low oil pressure or oil starvation that has plagued the high output Subaru EJ series boxer engines (EJ15, EJ16, EJ18, EJ20, EJ22, EJ25).
"King conducted extensive research into the unique oiling circumstances of the Subaru EJ series engines," explained Ron Sledge, King's performance and technical manager. "What resulted is a completely re-engineered main bearing set that eliminates oil leakage and increases oil flow to number two and number three rod bearings."
To improve oil flow, oil slots on the King XPG bearings are replaced with oil holes for better oil distribution in the groove and more consistent oil flow. Fully grooved number three main bearings enable 360
