2021 f350
I purchased this filter before and decided to repurchase them again, great filters and definitely stop dirt and dust. Great fitment will continue to purchase. I Did not experience any leaks or issues and I had them on for 6000 miles I decided to replace them at the same time I changed my oil.

Good quality
These are good quality filters and a good value for the money considering they’re less expensive from Amazon than they are directly from the company. No leaks from any of them. Installation is as easy as can be expected.

Don’t buy these
Stay away from this cheap junk regardless of the positive reviews. The under hood filter fit so poorly that it broke the retaining ring on the filter housing when rotated into place (also mentioned by other reviews). The quick connect fuel lines also fit poorly, leaked, and no matter how many times I primed it I couldn’t get the air out and couldn’t get the truck to start. I drove to the ford dealership and got the OEM parts for $129, put them in and it fired right up as usual, no leaks. I went against my better judgement ordering these in the first place, and it’s safe to say I’ll stick with motorcraft from now on. I’d like a refund but I doubt I can send them back soaked in diesel.
