F.Y.I NGK service bulletins on spark plugs and ethanol fuels

Interesting read. NGK is recommending cooler plugs and a slightly smaller gap if you are suffering poor mileage or performance with ethanol-blended fuels. They also recommend a 5 year/100,000km replacement interval on their ignition wires whether they look cracked or not. There is also some interesting info on high-flow air filters.

here are the scans. I hosted them on my site:

My last plug change I went with a colder plug. My car being 92 wasnt made with ethanol fuel in mind so with a stock temp plug itll burn hotter and create fouling. The colder plug isnt fouling and im sure its only helping my gas mileage a bit.
