Function of this part

The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.

Why this part matters

Without a functioning ECM, the engine will not start or will run poorly. A correct, working ECM is essential for performance, diagnostics, emissions control, and protecting the engine from damage.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Parts that fit!
It’s hard to find ‘official Mopar’ parts for the 3.0 Eco Diesel but Doc’s Diesel are exact matches and are as good or better quality as factory.

Just like the OEM filter
Color: 3 Set
I bought these awhile back before needing one. Did my oil change a couple months ago, wanted to wait a bit to review it. Fit is identical to the OEM filter, nice it also comes with new retention cap o-rings. Can recommend, seems to function as well as name brand/OEM and a good value since purchasing more than one. Literally got one for free compared to single purchase of 3. I drive my company 2012 Caravan about 35-40k a year, so I change my oil about every 3-4 months. I also have the upgraded all aluminum oil cooler, so I have to use this filter for the later models.
