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.
