    Engine Control Systems Ltd. of 165 Pony Drive, Newmarket, Ontario, Canada L3Y 7V1, has
    been found not to reduce the effectiveness of the applicable engine emission control
    system, and therefore, the Purifilters are exempt from the prohibitions in Sections 38390
    and 38391 of the Vehicle Code for installation on 1996 through 2003 model—year off—road
    compression—ignition engines of 20.0 liters or less displacement.
