Haven’t used yet, but think it will be a good thing!!

I thought it was a bit spendy, but after getting it, my initial impression is that it’s a very nice kit!! My only problem with the entire kit is the oil pressure sending unit adapter, made from aluminum. Screws into the block, oil lines connect to it as well as the sending unit itself. Too much weight as resting on this part and the first one broke. Sent a new one out and so far so good, but I think it should be SS. Otherwise, great bypass filter kit!!

No noticeable difference, but my CP4 HP Bosch fuel pump is still operational when most everyone else’s has broke and actually under a recall, all with 127,000 miles on it so I’ll give it the btd and give it 5 stars!!

Nice filter!! I can see why it’s as good as it is!! Top notch!!

Best filter I’ve ever used.

Love the results, oil analysis looks great even after 400K miles on my 2003 4Runner. Engine is going to outlast the body of my vehicle so I'm thinking of mods and a lift with new brake system and wheels.

Awesome filters, tremendous value, excellent design and quality. I’ve been running these filters for my GM 6L50 transmission. When the fluid was submitted to two different labs for testing after roughly 44,000 miles one of the labs asked why NEW fluid was being submitted for testing! These filters work

This is the best filter I have ever used. The filters were packaged carefully, shipped quickly, and arrived perfectly. I’ve been filtering my oil with these filters for more than 50,000 miles. Now…, the engine oil for my 2017 2.8L diesel is almost too clean to see on the dip stick!

We all know that as soon as you change your oil on a diesel, the oil turn black almost immediately. Well not any more. My oil remains clear for most of its life between oil changes, I wouldn't believe it if u didn't see it for myself. I had my oil changed at a local changer shop and the kid that did the change did the start up after the new oil was in. I was watching him from the cab as he was rechecking after the initial start up to circulate oil into the new filter. He pulled the dip stick to check and had a confused look on his face. Called over another worker and showed him the dip stick, both seemed confused or concerned. I stepped out and asked what's wrong. He replied, nothing, I've just never seen the oil remains clear after the startup on a diesel. I went in to explain the Aux oil filter to him. Score on for insane

Both the pressure source fitting & the return oil line to the oil filler cap function flawlessly, no runs, no hits& no errors. Good purchase !

I am very pleased with this oil filtration system. It was easy to install and well positioned on my engine. I did have an issue with the oil return cap, it leaked oil and made quite a mess. Their customer service was great and they sent me a replacement no charge. This has been a great company to deal with.

I installed the extreme2 oil filtration system on my lbz duramax over two years ago. I havent had to do an oil change on my truck since.

once a year I replace the factory oil filter and the extreme2 element, top off and i am good to go.

Prior to installing exteme2 my oil would get black with soot when i pulled the dip stick after a few days oil changes.

Now the oil stays transparent with a slight tint.

I also do like to send oil samples once per year to a lab for analysis.

These Italian oil burners are notorious for sooty/dirty oil and this kit is what should be included from the factory. The installation or should I say the "mounting of the Filter housing" does require you to have some mechanical ingenuity. I give all the equipment provided top notch scores for quality. The kit I purchased had exactly everything I needed to create a clean install.
I highly recommend this bypass oil filter kit to every owner of the 3.0 EcoDiesel.

This is a quality made part. To my knowledge Insane Diesel is the only company making this type of oil filter cap for the Ecodiesel. This unit is a functional non-wear item and will last for many years.
