This RICHWEI part number CF11671 (also listed as CP671) is manufactured to meet quality checks and designed to fit a range of Ram trucks, select Mazda CX-7 years, and the 2022 Wagoneer. Double-check your vehicle year, make, and model before ordering to ensure correct fitment.

Will this filter fit my Ram or Wagoneer?

Yes, the RICHWEI CF11671 is specified for many recent Ram heavy-duty and light-duty models and the Wagoneer. Verify compatibility with your exact model year and trim to avoid returns.

• Compatible Ram models: 2016–2021 1500, 2019–2021 1500 Classic, and 2016–2021 2500, 3500, 4500, 5500.
• Jeep Wagoneer compatibility: 2022 Wagoneer listed.
• Mazda compatibility: 2007–2012 CX-7.
• Use your vehicle’s garage/tool lookup or VIN to confirm before purchase.

How does the replacement improve cabin air quality?

This cabin filter captures airborne particles before they enter the HVAC system, helping reduce dust and larger pollen loads. While not an air purifier, a fresh filter maintains steady airflow and reduces visible debris accumulating inside vents.

• Multi-layer media traps dust, pollen, and road grit.
• Reduces clogged vents that can strain blower motors.
• Helps keep cabin surfaces cleaner by limiting particulate entry.

How simple is installation and how often should I replace it?

Most owners can replace the cabin filter with basic tools in under 30 minutes. Replacement intervals vary by driving conditions; inspect the filter annually or follow your vehicle manufacturer’s recommended schedule.

• Typical install: remove glove box or access panel, swap filter, reassemble.
• Replace sooner if driving in dusty or polluted areas, or if airflow decreases.
• Keep the old filter as a reference for orientation when installing the new one.

What’s included and what should I check before ordering?

Each purchase includes one RICHWEI cabin air filter packaged for shipment. Because OE and aftermarket part numbers can vary, confirm that CF11671 or CP671 is the correct replacement number for your vehicle.

• Package contents: 1 x cabin air filter (CF11671 / CP671).
• Confirm your vehicle year/make/model using online garage tools or your owner’s manual.
• Inspect the filter size and orientation label during installation to ensure proper fit.

Who is this for: This RICHWEI CF11671 cabin air filter is aimed at owners and technicians of compatible Ram trucks, the 2022 Wagoneer, and Mazda CX-7 drivers who want a cost-effective replacement that restores airflow and helps trap common road particulates. It suits DIYers who prefer a straightforward swap and fleet managers who need consistent, replaceable cabin filtration without special tools. Always verify fitment for your exact trim and year before ordering.
