I was just wondering which ones are the better of the two for a v-tec engine for instance mine is a type r motor. I was wanting to go with the ngk platinum but was also wondering using the ngk iridiums. Which of them two would you all prefer thanks for your replys.

 

I prefer the platinums

 

anyone else

 

used to use bosch platinums until they started to make the car hesitate then i switched to denso platinums and i have no problems. btw the denso pltinums are just like the ngk's really no difference.

 

Autolite 3924 or 3923 (sustained high speed driving)

or

NGK BKR6, BKR7

Gapped at 0.035 - 0.038

 

copper any good?

 

so are these good for any motor ....iv been trying to find a good plug for my jdm h22

 

why gapped so tight? isn't stock .44?

Widening the gap weakens the spark and you'll be more susceptible to blow out, especially with wilder cams.

On turbo cars a gap of 0.015 - 0.025 can be necessary.

 

anybody got the part number for the plugs....bkr6??

 

bkr6e-11
bkr7e-11

 

Platinums last longer than copper, but copper is a better conductor..

I use Denzo Platnium, not too bad of a price at Autozone.
