Tired of the rough idle in traffic...
One of them has a heat range between our factory stock plugs and the tr-6's, and the other is between the tr-6 and tr-7.
has anyone here used them?
the only time i have had a bad idle with them was on my truck around 40,000 miles, and once in b-mans car when i melted a plug.
sounds to me your plugs maybe gone, or tune is off

But compared to the stock plugs, they just don.t idle as well, and I mean theres a noticible diference.
So Dave, which set would be best?
The 82071's or the 82070's?
