There not bad, guess you could compare them to Auto Zone grade, but not to get a argument going, all replacement parts have been downgraded to some egree with all the off shore parts coming in. I can remember the NAPA/Echlin inition parts were top of the line but now there quetionable. Personally I think we shot our selves in the foot buying the imported stuff instead of spring for the good stuff and the good stuff has radually gone away. JMHO.
