Doc's Diesel Engine Air Filters:

Doc's Diesel Premium Engine Air Filters are made for hard-working diesel engines that don’t quit. They block out dirt, dust, and debris that can wear down your motor over time. The heavy-duty silicone gasket holds a tight seal, even when you're running in rough, dusty conditions, and deep pleated filter paper traps more grime to help your truck run longer, stronger, and more efficiently. The foam pre-filter catches larger dust to keep airflow strong and main filters clean, while helping melt snow and smooth hot turbo air without killing performance.

Product Details:

  • Includes 6 Engine Air Filters
  • Premium filter media maximizes protection against contaminants and minimizes unnecessary engine wear
  • Silicone sealing gasket ensures a proper seal even under harsh conditions
  • Foam Pre-Filter keeps your main filter clean and airflow strong
  • Embossed filter paper pleats trap more dirt and last longer
  • Easily install in only 5-10 minutes
  • Doc's auto parts all have an OEM design, fit, and function that meet or exceed OEM Requirements

Perfect fit, great quality!

This was a perfect direct fit and feels higher quality than the one that was installed by my dealer, and has an additional layer of filter material not on the one installed by my dealer.
