Re: P0303 and Coolant - Plug types
 

I once met a guy who was so fanatical about spark plug performance, he
would actually shim each one (indexing) so that the open end of the
electrodes faced the intake valve on each cylinder. He swore that he
gained 10+ hp. from this. I think he's been out in the sun too long.

I've tried every kind of spark plug ever made on a variety of vehicles.
I've never seen any differenc in either performance or service life
between any of them.

My preference: Champion Coppers which retail for about $1.39 each, the
choice of Cavemen everywhere.

Mongo like Chamipon but like Autolite a bit better. Think Autolite
heavier like large club, work good.

My belief is that putting in fresh plugs every 4-5k is a cheap
way of keeping an eye on the engine for any odd combustion.

Earle go Chevrolet dealer one time with exact plug specification from '85
Cavalier Owner's Manual that say AC plugs. First cave man Earle talk to say
"Chevrolet never use AC plugs". Second cave man say "That car use
Champion", try to give Earle plugs with completely different design. Earle
take Owner's Manual to Autozone, get right plugs, AC, just like come in car
from factory. You cave mans see Earle in TV?
