I do not think it was only the wires that made such a big difference. Sorry to say i was not very impressed with the performance of Champion #7570.  NGK!  |
In our collective experience (this site and others) - it IS the wires. It is also possible that the Champs weren't gapped properly.
There is nothing wrong with Champions, plenty wrong with the stock wires - they have high resistance and don't last.
Good to always change both plugs & wires together.
