Does anyone have any thoughts positive or negative about the pulstar sparkplugs. I've seen them advertised in Pop Mecahnics.

 

I think someone here tried those pulse plugs, and didn't like them.
Well....you will get a lot of mixed feelings about spark plugs, and who make the best,
and which ones work the best in these cars.....
Me....I like the NGK in my 745T.

 

normal copper are the best (NGK, Bosch, etc) - its what Volvo installed.
