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

I received one and it fit. Received another one 3 weeks later, then 3 weeks received another one. Called and spoke to a gentleman about it, got a shipping return label. Do not know why you kept shipping them

Everything fit good. Looked good. I couldn't find any filtration ratings anywhere. That would be nice to know. But besides that. I've been using various aftermarket parts for years. These are great.

Quality

Its not only this product. I buy quite a few products for multiple vehicles. The oil filters leak around gasket and sometimes filters need to be retightened about 1/4 turn. The last shipment the airfilters were under the weight of the oil and fuel filters and the pleats were folded over and bent/creased but not to the point of not being useable

Very pleased with both parts ad the videos that were displaced on the website. Saving money by doing it myself instead of dealership charge an arm and a legs. Will keep ordering products from this company, thanks.
