Champion to NGK cross reference

Recommended Posts

I called NGK and the cross from QL77CC to NGK is BR8HS. But when I cross BR8HS on champion's site it comes back with a QL78C. Research shows the QL77CC is an inductive resistor and the BR8HS is a regular resistor plug. The correct NGK number I come up with is BZ7HS-10 Can someone confirm the correct NGK plug? I'm having goofy tach problems on my 98 300PM.

I have only had luck with the Champion QL77CC in my 300 pro max........ and I HATE champion plugs. Sadly that is al I can run.

I doubt that your tack issue is plug related.

I figured the plugs wouldn't correct the issue, but it was a cheap try. I'm getting the orignal tach to try next week sometime. Got any idea until then?
