According to ACDelco, the new filters’ improved performance comes from a revised bypass valve design that features a compression spring-loaded nylon poppet that outperforms the current filter. These filters meet GM Powertrain performance specifications. Improvements include:

• Bypass valve opening pressure is increased from 100 to 150 kPa and is statistically more capable

• Improved level of robustness to water accumulation

• Filter media is no longer potted in adhesive, which can block filtration area

• Excellent cold-weather performance to minus 30 degrees C with dexos1 oil

• Hot oil durability improved thanks to elimination of adhesive.
