The guy at AutoZone went out of his way to write on my sparkplug box that I should gap the plugs at 0.54".

A half inch is a bit wide if you ask me but what do I know.

I gap mine around 0.054".

You should have said "Well Ill need some different plugs then."

Then proceeded to ask him for some for a big diesel.

Come On Now Wes

A teeny tiny decimal point or a little insignificant Zero

What possible difference could one or the other make

No Luck Needed

All you gotta do is

Go to a supply house that specializes in Import Parts

They keep em in the special section along with ........

Muffler Bearings
Blinker Fluid
and
Replacement Radiators for Corvairs ( JT will understand)

and

The most important tool needed to work on Imports :Word:

Metric Crescent Wrenches

According to our hoods (if any of you even have the stock hood anymore, lol) 0.054" I believe.

This is correct.

While were on this subject I have a question. What are the affects of changing the gap. On a mostly stock 5.0, what would gaping at .045 do, or .035 for that matter. I know most use a smaller gap when using nitrous or blown applications, but how will it affect performance on an N/A car? Can it help reduce detonation. I could use that. lol. Thanks.

They are hard to find, because they don't exist, right? Diesels rely on high fuel pressure and high compression to ignite the air/fuel mix, rather than a spark.

Correct. It compresses it so much, the atoms in the fuel air mixture get super hot from rubbing each other and explode. (Atleast that how it was explained to me)

Glow plugs are to initially heat up the combustion chamber for cold starts.
