from 2006 reviewsVery Good
I was looking for this part, and I was horrified by the dealership prices on this mandatory part. I found this site, and I ordered it. Had it in two days, and what savings compared to my local stealership. Thank you for getting me up and running again. Very impressed.
They were the OEM filters at a decent price and the shipping was fast. Will order again
Mopar 2022 to 2024 Ram 6.7L Cummins Filter Kit
Well worth the cost, an essential upgrade for a tuned motor. True bolt-on performance.
It is the right sized filter for the application. Since FAS decided to discontinue their own filter and replace it with the wrong size, I'm left with no alternative but to purchase the Fleetguard. I guess that I do have another option, I can update the filter block to go to the new sized FASS filter but....why?
I'm so glad I purchased the Best dampener for any engine. It's extremely well made and does what it should. You can’t go wrong!
This works great for my 2019 Dodge Ram 1500. It was easy to use, and I haven’t had any issues since. I am very happy with my purchase. Fast shipping and excellent price compared to my local dealership.
Bought this thermostat for my 2018 ram 2500 6.7. At 62k miles the oem stock thermostat failed open. KLM had the newer version and fit perfectly. No issues after install and working as it should.
The Fluidampr 800191 provided engine smoothness and performance, particularly for my 6.5L diesel engine. While it might be a bit on the pricey side, the smoother operation and improved performance are well worth the cost.
Great product and was very each to install . Fitment was spot on and exactly what I needed .
KLM was very professional. Their product was 2nd to none. I will recommend KLM products to anyone. Thank you KLM
Part was OEM quality and went in perfectly. Thanks KLM!
Cabin filter arrived and fit exactly like the original filter.
