[V8] NGK Spark plugs

[quattro + 5 or 8 = fun]

I was doing some research on what plugs to put in the V8 quattro and came
across this blurb from one of the Toyota user groups.




"Here was NKG's response to my email if anyone is interested:


NGK Spark Plugs produces many different types of spark plugs. Each using
different materials and designs. I will summaries each for you.

Standard - Copper Core, nickel alloy ground, nickel center electrode tip 2.5
mm diameter. Nickel has a low melting point of 2600 degrees

V-Power - Same as the standard spark plug however we cut a v in the center
eletrode in order to force the flame kernel to the outer edge of the center
and ground electrode. This improves flame growth and ignitability.

G-Power - Copper Core, Trapezoid nickel alloy ground electrode, .6 mm
diameter platinum center electrode tip. Platinum has a melting point of 3200
degrees. The smaller tip takes less voltage to fire, which intern means
faster flame growth.

Iridium IX - Same internal characteristics as the GP series however it has a
taper cut ground electrode and uses an iridium center electrode tip. Iridium
has a melting point of 4400 degrees. This spark plug will provide the best
ignitability and best anti fouling.

Laser Platinum - Internally the same however has a platinum center electrode
tip and a nickel alloy ground with a platinum disc welded to the back side.
This spark plug will provide good ignitability as well as slow wear rate so
the spark plug will perform at it's optimum for a longer period of time.

Laser Iridium - Internally the same however has an iridium center electrode
tip and a nickel alloy ground with a platinum disc welded to the back side.
This spark plug will provide the longest service life and best
ignitability."
