I had trouble finding a MOPAR SRT Oil Filter from my normal sources. I found DieselFiltersOnline.com and they had it for a great price. I am still impressed that it came super quick the day after I ordered it being I placed order in the late afternoon. I will be using DieselFiltersOnline.com for my filtration needs moving forward. Thanks again.

Thought I would never find a replacement fuel filter for my dodge extreme duty diesel. Mopar quit making them. Got the information I needed from support with three options. Went with the Mann filter. German made so you know it’s right. Bought four as I like keeping one spare in the truck. Really fast delivery too. Bookmarked these folks for future buys. Appreciate y’all for the great service.

Literally hands down best compnay ever bought filters from , I buy filters for 7 trucks constantly and they always get what i need, if there is a mistake they fix it and i mean fix it fast and make it so smooth, i will never buy from anyone but them. Solid normal people who treat you like family by a simple phone call. 100k percent the best in the business and the best on price. Blessed to have them as a supplier.

I received the filter the next morning as promised. The original delay was not Diesel Filters fault. I was surprised and impressed with the level of communication from Diesel Filters. They will now be my first source for all my filters. Thank you

Shipped quickly but UPS was a bit slow as it took 2 weeks to get from the east east to the west coast. Thanks to tracking number I could at least tell where it was. The primary fuel filter looks different will have to confirm fit.
