This filter really surprised me on how efficient ir works. I purchased the by pass kit for my '16 Ram 3500 dually, only issue was locating proper position for it. My trk has dual alternators, no room under hood area. Excellent filter very satisfied.

Amsoil Best dam products on the planet.............. Bar none...........

Great product. Easy install. Recommend the line brackets by Don Smith if your putting it in a DuraMax

Great product but a little on the expensive side.

I purchased this item and bypass remote mount and attached to generator which runs 24/7 . mounted external pump and timer. each 3rd day oil filters. no more expensive weekly oil changes. shut down only when i have to change filter.

First off, this thing is BIG!!! Make sure you check truck for a place to mount. Very good quality!! Easy to follow instructions.

Installation was a breeze. After 3K miles oil is noticeably cleaner. I use this truck in a hot shot trucking service so good oil flow and filtration is critical. Five stars for the filter system. Four stars, will have to reevaluate after first oil sample analysis. See how well the system truly works.

According to the oil analysis, it's doing it's job. I'm changing it out at 30,000 mile intervals.

Product works as designed purchased metal bracket from another vendor to complete job and looks great

Super easy to install works great

Best oil filter hands down

Look, I have no idea if they actually help the engine, but I love the concept and I am too lazy to do oil analysis to find out more. One real benefit was when my oil sending gauge showed zero as I was climbing a grade with a 41' 5th wheel, I was able to pull over and remove the oil fill cap to see the oil still pumping which saved our trip. If that's not making sense, their kit for these filters has the return line going into the fill cap, hence the oil stream.

its a great product price way too high

Thanks so much for this product. Installation is easy. More importantly is my oil looks so much better now after only a few thousand miles.

I put the Dual Filter System on and switched to the top Quality Oil and Filters on my GMC gas powered 2500 pickup in 2000 when the truck was new, and purchased to tow a 34’ Airstream Travel Trailer. By 2004 I had put just over 100,000 miles on the truck with about 90% of that towing the trailer. Changed the oil one time each year and the filters two times each year and had no problems at all. I purchased a 2004 GMC Duramax Diesel 2500, again for towing the Airstream. I installed the Dual Filter System After breaking.. I put 125,000 miles on the truck mostly towing the Airstream, then sold it to a friend that told me yesterday he had 212,000 miles on it now using the AMSOIL and Filters I supplied him. I purchased a 2015 Chevy Duramax 3500 the day I sold the above truck. I installed the dual filter system on the new truck, and took off to Alaska for the second time towing the Airstream trailer. I now have 63,00 miles on this truck with no problems. I still change oil and filters on the one time per year for oil and twice per year for filters. I am a very Happy AMSOIL Customer!!!

These are awesome filters. They allowed me to extend my drain intervals (using oil sample kit) to over 35,000 on my duramax diesel in my pick-up. The Lab kept telling me to go another 5000 miles after each test, once I got to this point, I decided I don't drive that many miles a year. I now just change oil before our long trip each year( towing firth wheel with a flatbed behind that.
