Air Filters

摘要

The gasket on the back side of a K&N induction air filter (p CP0711) came loose and was sucked into the engine, causing it to stop running. This air filter is not an OEM product and was installed with an STC and logbook entry. A different company had the same problem, which resulted in AD 96-09-06. Called company, which said they had no problems. Part total time: Unknown Receiving inspection of new air filters (p P107336) revealed three out of four had a defective sealing surface, causing the sealing/mating surface to crack and crumble. This defective sealing surface could potentially enter the engine. The defective filters' sealing surface has a light-gray color while the replacement filters we received, inspected and found to be in serviceable condition had a dark gray, almost black sealing surface. Suspect that the defective filters had improper material on the sealing surface or were improperly cured. Part total time: 0.0 hours.
