Which one is better denso or nkg both being aridium or if there is one better than those two.

 

i think
they are the same ...
denso / ngk .. same spark plug...

not sure

 

Gotta go with the NGK iriduim plugs. :D They are the best ones to work with,

 

denso and ngk are not the same i cant WAIT till the autolite XP plug comes out till then either NGK or DENSO iridium

 

what is so good about atuolite compared to ngk and denso?

 

autolite is supposed to be for american cars. Whats the difference between the regular and the XP?

 

I Used to only use Bosch Platinums, but when I started getting into Japanese cars, I found that ngk worked the best for me. Just whatwver you do, don't use splitfires... one day at the dyno I seen a guy jump 10hp (sportster 883) from swaping from splitfire to regular old Champion plugs

 

i got some platnum plugs for my 30K service. i think i can go longer than 30K now. ill pick up the iridum plugs next service. They were special order from the parts store and i wasnt waiting for a day or two for spark plugs.

 

the xp is a irridium plug....its a .6 irridium finewire core double platinum sidewire design and with this design they have increased the kernal flame making it a HOT plug making it fully burn everything here you can check em out
