Champion 1 piece spark plugs suck

I might not suposed to bad mouth brands but....About a month I replaced my factory 2 piece spark plugs (55000 miles)with Champion 1 piece plugs.... ever since I've nothing but trouble with them... 

The car was skipping and acting weird...1 or all must be bad or maybe they just don't work well in a 4.6... I must have regapped them 4 times starting at .035 ending at .048...So that was $102.00 down the drain... I got pissed and stoped at AutoZone and bought a set of HT1 (another $102.00) and installed them last night and the car runs great...so save yourself some $$$$ and don't use the Champions....

On a good note.. the company I bought the Champions from told me to send them back for a refund...they must know something I don't.
