So i'm going to replace the plugs on my 929 and was lookin at sparkplugs.com for a start. Does anyone know the difference between the Denso and NGK plugs aside from the shape? Also, is there a difference between the Denso plugs that sparkplugs.com sells vs. the ones offered by the local shops for ~$26-30 per plug?

Of course i'm leaning toward buyin the Denso plugs online cuz of the price but just wanted to know if there was an actual difference to consider.

Can't got wrong with NGK. I wouldn't chance detonation with cheap plugs...

Just my .02
