Does anyone use anything other then Champion plugs in they're 99 outboard?

If so what type and does it mess with the ECM?

In my 97's I run NGK BUHW surface gap plugs. I don't see how it would effect the brain...

NGK

I was told from Merc. Racing that Champions were motorola compatible or conpliant and that's for the ECM.???

I'll try NGK Iv'e liked them in my street cars in the past.

Thanks
