Duramax 6.6L Bypass Oil Filter Kit "Under the Hood" (2020-Present)

I love these filters. Easy to change and they do a fantastic job at filtering the oil.

Nice well made filter housing, installation was pretty easy. Made a guard for it to help protect oil line fittings from something being thrown up by front tire sense it is a frame mount. Happy so far as as long as it filters as good as they claim.

I apologize for the late response.
After 300 miles with first time Lorenzo's oil in my 2003 7.3; the performance is so smooth even pulling loads. Starts right away, the machine sounds a little quiet, the acceleration is faster, just amazing results.
In my previous oil maintenance, I always added oil treatment, getting good results.
When I saw Lorenzo's oil for the first time, I saw quality, a custom made oil product for heavy duty machinery even smell good.
I think Lorenzo's oil is a good investment for my business vehicle.
Also, I'm using the Extreme Oil Filter.....so it feels like driving a brand new truck.

Thank you for the engineering team for this product .

Easy instal, quality parts

Well packaged, the kit comes with all hardware and plenty of extra hose for either the second alternator location or on the frame rail next to the standard oil filter.
An update to the install guild would be the location of the bypass filter it self for frame mounting on a 2013 and like duramax’s. The passenger side location is occupied with a DEF fluid tank or exhaust pipe. Other than that small detail the kit was simple to install. First time making AN fitting but the kit made it simple to follow. Will purchase again for another truck in 1million miles.

Great job guys. Quality parts. Inspected everything prior to install. Remember to knock off the helicoil tang on the inside. Mine was still attached. I'm a machinist so I naturally take note of fit and finish. Made an install video for YouTube on my 2024 LZ0. Made in USA! Thank you!

Great filter that is way more secure than other brands that use adapters and spin on filters that can come off and ruin engine. This product is much more safe and secure and reliable

I needed to get this oil bypass filter and get it fast, because it was moving. There was a back order and I was t going to be able to get it in time. So the salesman did some magic and.moved a few orders around d and bam, I had it within 4 days. It installs easy and looks great. I could t be happier. Insane diesel is for sure a very professional and customer service oriented company. You cant go wrong doing business with them. Tha KS again insane diesel

I just had my engine oil analyzed at 10,000 miles. I use insane diesels oil filter. The content was .53% one of the lowest readings they’ve ever seen. My engine oil was still good the quality of insane diesel products and easy abuse, or incredible. I highly recommend everyone to get a remote oil filter with a modern day diesel. There is a reason all long haul trucks have them because they work.

Ford 6.4 diesel with 350,000 miles. With using T6 and OEM oil filter, best investment ever was adding Insane Diesel oil by-pass and their oil cooler. My oil stays clear to about 2,000 miles and this soot starts to build. Did a BlackStone oil analysis at 8,000 miles and they stated almost no wear materials and oil was good for at least 12,000 miles or longer. It's expensive but worth it. Great support and very professional.

It's always a pleasure to doing business with y'all.

I am thoroughly satisfied with the construction, quality, and well thought out design. One small note, I assembled/inspected all components on the bench. In the lower threaded hole, the threads had a piece of swath or thread-cut that was binding the bolt. After cleaning with a pick tool, I was able to remove it. Everything fits perfectly and was a simple install. Don’t forget to double check the threads. Still 5/5 would recommend.

Everything fit as it should can't wait to see the benefits! Fast shipping. Build quality is excellent

Very good product

Great stuff
