This bypass filter pushes quite a bit of coolant through it - I can see it flowing in the coolant reservoir. I had debris in my heater core that caused issues and needed to be flushed. No more! Easy enough install and looks great too. I’ll cut the filter when I replace it to see what I caught. Double check the valve screws for tightness. I lost one and am hoping for a replacement from Sinister. Hopefully no questions asked. 2016 Ram 2500 Cummins

Quick shipping and great quality product. Had to modify the the mounting a bit to work with my intake but installed like it should.

Bracket doesn't look like the one pictured above in the ad.After 2 hours of work...last step reinstall airbox lid. Lid does not fit. The bracket used in this kit positions the coolant filter head on top of the maf sensor on the intake. Contacted sinister diesel tech support, tech guy says my truck is special. They sell hundreds each day without issue, except mine, he exclaimed. His solution was to return the kit to Amazon and to not purchase it again.I'll fab a working bracket to salvage the parts and my time. I do NOT recommend this product.Label on the side of the sinister diesel box says for truck years 2013-2018. My truck is a 2017.

First off I’d like to say the fit is horrible. I had to bend the mounting bracket to even get the filter on. The intake hose is too long while the return hose is too short... also the only way to fit the return fitting is to let it hit the sensor on the oem air intake as well as let the hose hit the hood. Mine ended up rubbing a hole through the hose from sitting on the air intake. Good idea, very poor design. Save your money
