Correct part (Mopar MO-349) but shipping method could be improved.
Size: 1 Count, Size: 1 Count
I received what I ordered, Mopar MO-349 oil filters. However, they were shipped in what looked like an oversized paper bag and the boxes that contained the filters were crushed (see picture). They should have been shipped in a small box instead of a giant paper bag. The filters look ok but I guess I'll know for sure when I try to use them. Plus 4 stars for the product. Minus 1 star for Amazon shipping.

Best oil hands down
Size: 5 L
This is the only oil I use now, my mechanic recommended it. Works great in my Mazda3, runs smooth and no leaks. More expensive but, worth it.

Best Oil on the Market
Size: 5 L
I’ve used this and only this in my 15 Scion FRS since I bought it . I used to change it every 5k but I retired and now it’s a once a year oil change with less than 5k per year. The car has never had any issues with this oil . Since NASCAR changes oil in the cars every 500 miles I don’t whine about changing it once a year. $40 for oil is better than $10k for another built motor
