Description Of Change: The new NOx sensors are resistant to currents and voltage from other electrical components.

Adaptable To: The following changes are adaptable to the products within the listed serial numbers, and are effective with all products after the listed serial numbers.

The new 441-5127 Nitrogen Oxide Sensor As (Engine Out) replaces the former 359-9171 Nitrogen Oxide Sensor As (Engine Out).

The new 441-5128 Nitrogen Oxide Sensor As (Tailpipe Out) replaces the former 359-9172 Nitrogen Oxide Sensor As (Tailpipe Out).

The new NOx sensors are adaptable to the above engines back to first production.
