I have used the the dual filter system since 2001. Love the extended changes and cost savings.

Great product easy install, very straightforward. I also installed Don's oil bypass guard and highly recommend that at same time.

Never used a bypass on my cars but wouldn't be without one on a diesel. Come to think of it, I just might start putting them on my cars as well.

Nothing but amsoil for me

Amsoil is definitely one of the best products on the market. Amsoil if the only lubricant I use in all of my equipment.

Hard to find these filters anywhere else. And decent price I bought them for my secondary oil filter on my 2008 f350 and they fit the sinister diesel kit

The filter does a good job allowing me to do extended drain intervals. I sample every 25,000 miles and determine my oil changes from the results. I do wish they made a shorter version as I have limited space.

Can't find a better solution to fine particle filtration and I recommend this to all my friends as the best protection money can buy for your mega expensive high-end diesel engine...

Excellent product, it filters unwanted residue.

Fairly easy install using mounting brackets I purchased from Don's oil (youtube). I have 1000 miles on the oil and it looks a lot cleaner so it's doing it's job. It increased my oil capacity by 3 qts.I wish they would use a standard Ford 6.7 mount though for the primary filter.

This system is still in it’s infancy as to my assessing of it’s performance, but it is DEFINITELY a more user friendly, higher quality, less expensive, and easier to order system than my previous Bypass System. I’ve been using Amsoil products for nearly 20 years and I have NEVER been disappointed by their quality and support. If their past is any indicator, I’m sure this Bypass System will exceed my expectations greatly.

This installed on my 97 7.3 and keeps my oil from getting too thick with soot. works great.

bypass filter came on the dixie chopper mower. just replaced it with a new one.

Machine work and finish looks really good. Have not installed yet. So unknown on performance.

Great product.

Recommend for Cummins ISX 15

Great filter

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
