Bosch Urea Diesel Filter

Medium and heavy-duty trucks manufactured starting on January 1, 2010, are required to meet the EPA Emission Standards. The majority of truck manufacturers chose to use selective catalytic reduction (SCR) technology to meet the standards.

As part of SCR technology, Bosch provides the dosing system which injects urea into the exhaust which interacts with the SCR catalyst to reduce the NOx emissions level. The supply module contains a main filter which filters the urea being pumped into the dosing module. The filter needs to be replaced per the manufacturer’s scheduled maintenance requirements.

The Bosch Urea Filter (part #1 457 436 033) for diesel applications is designed for and supplied to OE manufacturers, and offers one SKU which covers up to 69% of Class 4 through Class 8 trucks in operation.
