Frantz Filters now offers an expanded line of Duramax, Cummins, and Powerstroke bypass oil filter kits. In addition to the company’s universal kit developed for gas and diesel-powered vehicles, Frantz now offers custom designed kits for the most common diesel-powered trucks and vans on the market. The new kit applications include the Ford Powerstroke 6.7L, 7.3L, and dual model kit for the 6.0L/6.4L Powerstroke, and three separate 6.6L Duramax/GMC kits for years 2001–2016, 2017–2019, and the current 2020–2021. Frantz has also introduced a kit for the 5.9L and 6.7L Cummins that can be configured based on model year. Parts can be ordered for many other makes and models by working with a Frantz Filters specialist.

The Frantz filter is engineered to provide an endless supply of clean oil to the engine. With a 4.5 in. depth of filtration, more than any other system on the market, the Frantz bypass filter kit filters engine oil ten times finer than an OEM filter, down to two microns. All solid contamination including wear metals and dirt are removed, engine oil is kept cooler, and excess moisture and water (the catalyst for rust and corrosion) is removed to extend the engine’s life and performance. 

Frantz filter keeps oil analytically cleaner than brand new oil. Based on a third-party test with Blackstone Laboratories, after running dirty oil through the Frantz filter on a 6.0 L Powerstroke F-350 with over 215,000 miles, the particle count revealed just 1,641 contaminating particles at two microns - a 96% decrease in contamination.

Developed as an easy to install bypass filter, the Frantz filter kit installs in under an hour and all necessary hardware is included. The kit is ideal for Class 1 to 3 trucks and SUVs, especially fleets that require many hours of idling or continual use where oil change maintenance intervals are frequent. Installation greatly reduces downtime maintenance of fleets that require oil changes every 5,000 to 7,000 miles. Extended oil change intervals saves both time and money and ensures that only high-quality clean engine oil is circulated through the engine oil system to keep the engine and components working at optimum performance.
