Yep NGK all the way. cept in a volkswagon I ran bosh in my Turbo Fox.

Well I bought NGK Platinum today.  They have Iridium plugs too but they were the most expensive.

Next I gotta get the cap and rotor.

Under the hood there is a spark plug
# for NGK, Denso and Bosch plugs, my
own preference is NGK or Denso in
Japan made cars and Bosch in Euro
cars and Autolites or AC Delco in US
made cars, seems like the right thing
to do, tho I have had problems with
NGKs in a Motorcycle, and a constant
one, so I grabbed an old worn out
Bocsh plug from my VW Bug and never
changed it again, go figure

I'll second Wildgoody's comments

Japanese engines seem to like NGK

Bosche seems to work well in European cars other than Italian

American stuff seems to like Autolite and AC

Nothing seems to like Champion (except race engines cause they make the best selection of heat ranges and it just don't matter how long they last, it's a race car)

FWIW

Italian cars don't run well no matter the plug

Notice I didn't even mention those, never got any
life out of Champions, they just seem to be junk

Champion plugs were by the far the least expensive. I had those in my ride many years ago and boy did they suck.

NGK and Denso are the same plug, just sold under diffrent names to difrent auto parts stores, go to shucks and ask for a Denso plug, the guy will likley look at you stupid.
I mean shucks and Autozone cant have the same line of "premium spark plugs, kind of like the air and oil filters, and a few other things" used to be a Manager at shucks.

and as far as shucks saying well our autolight alternators are the best things on earth, they are verry good, however the same company makes reman altenaators for 2 other auto parts suppliers, under a diffrent name then auto light.  

any way my 2bits

I thought Nippondenso and NGK were
two different companys, and Denso was
just short for the long name

Last I knew,  well they are sister companys, GM and Chevy, Benz and Dodge, Dodge and Jeep,  but it is prety much the same thing, take the 2 and put them side by side, V-power diode and everything the same, and the V-Prong is patened!
