Strange they say that because i am running the BRISK GOR15LGS

An find them great so far...

The other ppl that are running them have the same mods as me ++
and have been running the same plugs for over a year now no probs....

My car has been sitting because of the snow we have here
and i fired her up tonight touch of the key....

Well first chance i get i will take her for a nice run and will keep
doing test for the next 6 months to see the difference....

Can i ask who you were dealing with ?
And will pass this info on to the ppl here and see what is going on ok.

Thanks John
