Good. Good price. They are what they say they are and do the job. Have changed a few oils with these and no leaks.

Stop re-using your old crush-washer to save a few cents. Buy this pack now.
Way more economical than buying them one-at-a-time from a Dealership. I have had these for several oil changes, and experience no issues. Mazda 6, 2016. Manual says 4.8 quarts, but I buy a 5-quart container, dump it all in, then use the now empty container to hold what was drained from the car. I can say conclusively that the car is neither burning excess oil (or seemingly none at all), and that these crush-washers aren't permitting leaking, because I can see that the drained oil fills up the 5-quart jug to near the top. I'd absolutely buy these again, and absolutely from this seller.

Genuine OEM crush washers.
Not much needs to be said. The 9956-41-400 is a genuine OEM, 14mm aluminum crush washer/gasket designed for Mazda engine oil drain plugs. I've used them for several oil changes now in my 2015 Mazda CX-5 and 2016 Mazda 6, and no leaks. Enough washers for 15 oil changes at a good price. 5 stars.

Nice stock item for maintenance jobs
You need these for oil, differential and transmission fluid changes, small investment for future maintenance Save a trip to the auto parts store and save some money
