Works Fine at a lower cost

I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.

A mediocre gasket

I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
