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:

  • 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

Very nicely made

Fit and finish was top notch. Very well constructed. Refreshing to see such quality from a part. Usually there’s something not right with parts but we run them anyway. Thanks Docs!

Docs makes these air filters and ships them out fast, all the parts stores around my area are a week or longer to get them in but docs can have them in a few days. I will continue to order from docs for all the trucks in my fleet
