Product Details

Delphi AS10267 is engineered for vehicles that rely on knock sensing to help the engine control system detect abnormal combustion and adjust timing accordingly. It is a fitment-based replacement for many Ford truck, van, and SUV applications, including 1999-2010 Ford F-150, 2000-2004 Ford Expedition, 1999-2004 Ford F-250 Super Duty, and 2004-2011 Lincoln Town Car. This part cross-references Standard Ignition KS57 for the same application.

Delphi’s OE experience is built into the aftermarket design, giving buyers a sensor that follows the original mounting and connector style used on supported vehicles. The AS10267 part number is also referenced in service and catalog searches for Ford E-350 Super Duty, Mercury Grand Marquis, and Lincoln Navigator applications.
