Exactly the same complaints here. Searching back some posts will find the thread discussing this when I had my misfires.
Misfires started happening for me 1 month after installing, because of the boots not sitting flush on the valve covers. I replaced my plugs with Denso Iridiums, properly gapped, cleaned inside of boots thoroughly, and added dielectric grease. No misfires since. (knock on wood)
But with the poor fitment, I am worried it will happen again. I didn't have time to contact Magnecor about the fitment, so I just left it, but if a replacement is possible, that would be awesome.
