Cabin Air Filter

The cabin filter handles the other side of the truck’s filtration system: the air entering the passenger compartment.

An electrostatic filtration layer helps capture fine airborne particles entering through the HVAC system. The supplied maintenance recommendation calls for cabin filter replacement approximately every 12 months or 12,000 miles.

Ram Engine & Cabin Filter Fitment Guide

Fitment depends on both model year and engine.

Ram 1500 Fitment

According to the supplied application information, this filter kit fits several Ram 1500 engine combinations.

3.0L Diesel

2020–2023 Ram 1500 3.0L Diesel

3.6L Gas

2016–2022 Ram 1500 3.6L Gas

3.6L Hybrid

2019–2026 Ram 1500 3.6L Hybrid

5.7L Gas

2016–2024 Ram 1500 5.7L Gas

5.7L Hybrid

2019–2024 Ram 1500 5.7L Hybrid

Does Not Fit Ram 1500 TRX

The supplied fitment specifically excludes:

Ram 1500 6.2L Gas

Ram 1500 TRX

If you own a TRX, this isn’t the correct engine/cabin filter combination.

Ram 1500 Classic Fitment

The kit is listed for:

2019–2024 Ram 1500 Classic 3.6L Gas

2019–2024 Ram 1500 Classic 5.7L Gas

It is not listed for the 3.0L or 6.2L Ram 1500 Classic applications.

This distinction is important because the Ram 1500 and Ram 1500 Classic aren’t interchangeable names when determining parts fitment.

Ram 2500 Fitment

The supplied application information lists:

2016–2019 Ram 2500 5.7L Gas

2016–2018 Ram 2500 5.7L CNG

The kit is specifically not listed for the Ram 2500 6.4L or 6.7L.

That means owners of a 6.7L Cummins-powered Ram 2500 should select a different filter application.

68441763AA Engine Air Filter Cross-Reference

The engine filter is listed as a replacement or cross-reference for:

The multiple reference numbers make it easier to compare the replacement filter against the filter already installed in the truck.

68406048AA Cabin Air Filter Cross-Reference

The included cabin filter is listed as a replacement or cross-reference for:

These numbers are provided as cross-references. The filters in this kit are aftermarket replacement components and shouldn’t be represented as genuine Mopar parts unless the actual product is manufactured and branded by Mopar.

Why Replace Both Filters Together?

The engine and cabin filters perform completely different jobs, but they’re both routine service items.

The engine air filter helps prevent airborne contamination from entering the engine through the intake.

The cabin air filter cleans incoming HVAC air before it reaches the occupants.

Replacing both at the same time gives the truck fresh filtration on both sides and makes it easier to establish a maintenance schedule.

For additional engine-side filter and airflow maintenance information, Pro Street’s Cold Air Intake Cleaning for Better Airflow guide explains how air-filter condition can affect an intake system.

Engine Air Filter Construction

The supplied product information describes the engine filter as using quality filtration media combined with a heat-resistant frame.

A properly fitted perimeter is particularly important on an engine filter. Intake air should travel through the filtration media rather than bypassing it around an improperly seated edge.

During installation, inspect the airbox for loose dirt and debris before installing the new filter, and verify that the filter is fully seated before securing the airbox.

Cabin Air Filtration

The cabin filter incorporates an electrostatic filtration layer designed to help capture fine particles beyond what basic nonwoven material alone may capture.

The supplied product information recommends replacement every:

12 months or 12,000 miles

Actual service requirements can vary with operating conditions. Trucks frequently driven on dusty roads, construction sites or other high-particulate environments may require more frequent inspection.

Verify Your Ram Engine Before Ordering

Don’t purchase this kit based solely on seeing “Ram 1500” in the title.

The engine matters.

Before ordering, confirm:

Model year + exact Ram model + engine displacement + engine type

For example, a 2022 Ram 1500 5.7L Gas appears in the supplied fitment information, while a 2022 Ram 1500 TRX 6.2L is specifically excluded.

Likewise, the listed Ram 2500 application is centered on the 5.7L, not the more common 6.4L HEMI or 6.7L Cummins applications.
