So heres my little ditty on what I feel the difference between the 2 mind you this is just per butt dyno and everyday use. I also want to add I did a custom grounding plate for the coil over packs for the ignition (that is a whole different story)

So the plus and minus between the 2
bosch costs more depending on where you go
bosch felt like it put out more in the higher RPMs.. (since I have the hondata reflash at about 7200 where redline use to be I notice a slight more kick then what I did with the denzos)..
the denzos have a better cold start
also felt the denzos last alittle longer.. not sure if its due to my custom grounding plate or not.
my conclusion
per butt dyno the denzos are good if you are looking for alittle more long lasting kick but dont cut it in the high RPM range.. if you are a habitual spark plug swapper regardless of what the book says for changing like myself then the bosch are up your alley. Soon I will be getting the pulstar plugs and will give a 3rd opinion on that as well.. Feel free to ask me about this topic and keep it sparking!!
