What is better for a BMW, pulse plugs or traditional ones?

Soon I have to perform the standard mantainence of our car and I have been reading about the new pulse plugs that promise better performance.

Is this true? They are very expensive ( 25 dollars each) and I don't know it they are worth it or is it mearly a publicity stunt or scam?

HAs anyone used them in a BMW or other European car? Should I experiment or stick with traditional Bosch ones?

Thxs a lot for your input!!What is better for a BMW, pulse plugs or traditional ones?Stick with the Bosch plugs, they are high quality and will work just fine with your Bimmer. I use the Bosch +4 plugs in my 520i and they are great.What is better for a BMW, pulse plugs or traditional ones?Waste of money. To answer your questions stick with the Bosch, EVEN BETTER, use Nippon Denso. The Bosch + 4's require too much spark and the Nippon's will provide more consistent spark and reduce any potential of misfires.
