Ngk Or Denso?

ive been looking for prices for spark plugs and found out that there are 2 companies out there, almost actually one company as i understood, and they both have iridium plugs i need but with a price difference, so now i'm lost. which one should i get? does any1 has any experience with them?

i think ND came out with them first a few years back. i remember seeing an ad in a dealership in japan. but as far as which company i think ND is oem to lexus so i would use them

NGK plugs in all of my vehicles (Lexus & Suzuki GSXR) except my '87 Ford Truck and boat. NGK makes the best plug on earth. It's worth the $.

I'm putting NGK's in my boat this weekend. I don't care about the old truck's plugs. Don't drive it enough. It's for pulling the boat and hauling stuff.

the denso's are real pricey but are good for the forced induction engines

but minimal differences in any others

ngk's are also good

how much were the ND plugs compared to the NGK? do you feel a difference??

85$ for the set of 8 ND and 65 for the set of 8 NGK

both of the them are iridium

when there is a price differenc like that i usually buy the more expensive ones because they cost more for a reason right? i may be wrong but i can say mine cost more :P do you feel a difference in performance at all???
