I have been using NGK B8ES plugs in my SIX.
Seems to be nothing but great performance.

Is there a better plug?
I pulled one out today and it was dark tan/gray.

What does the NGK code mean, anyway?


thanks

NGK's rock!

you have a cdi box.. you can go to a colder plug if it doesnt foul (8 is up there tho)

NGK website lists what the codes mean...

the number (8) is opposite to bosch....

i thibk NGK states a b6ES for a 914/4 .. and i went to a colder plug 5 or 7.... cant remember probably 7

there are some really sweet racing plugs out there if you build that new high compression engine....

but they get kinda pricey though
the one's I'm coveting right now are $$$$, but provide actual clearance and actual dyno hp.....

B8ES is a REALLY cold plug. Like what you'd run in a 2.4 911S with MFI if you only drove it on the highway. The Cap'n

MSD box reccomends an MSD high output low impedance CDI coil...
Mallory Hyfire box reccomends the same...

you will like the small packaging of a mallory promaster Ecoil...

the difference is in the resistance.

bosch blue coil ~ 3ohm.
CDI coil. 0.9 ish ohms....

dont exactly recall....

big difference.

your plugs are fine if they arent fouling. (cold enuff)

I think the Blue coil was one of the acceptable coils for both the MSD and Pertronix applications.

I noticed today that the stickers on my blue coil are shriveled, as if from heat? (IMG:style_emoticons/default/confused24.gif)
