the thing with champion shit is its not a matter of 'when they fail' its always a case of 'when' they fail and the damage they do when they fail, if your lucky you have a missfire and just a plug change, other than that it will cost you an engine.
they are crap - its worldwide known - there renown for being shite.
your lucky to get a 1000 miles from a set of there race plugs - ok there cheap - but if your thing NEEDS race plugs why scrimp on cheap plugs ?
