Wow

Thanks for that. I=E2=80=99ll certainly bear it in mind. Likewi=

For me, i prefer Champion plugs plugs to NGK, but that=C2=B4s a
matter of taste. I think both, Champion and NGK, are of similar
quality. Matter of taste, as I wrote. But NOT the car
manufacturer determines the plug gap, its the plug
manufacturer. Definitely the car manufacturer takes this for
his specs in the workshop manual.
There is to much hype about plugs anyway. I am working as a
professional, Elecrtonics and Elecrtrcian engineer, at a big
classic car parts supplier here in Europe and I never go away
from the given plug gap as set by the plug manufacturer.
Austin-Healey engines are not high tech, they are tractor
engines and can take a lot of misfit, but anyway BMC knew at
the time what=C2=B4s best to do with them, even its printed 60 =
or 70
years ago.
Some people try to adjust the fuel mixture with a CO-tester.
You can do that, but it doesn=C2=B4t give best results for road=
use,
especially in hotter climates and high above sea level.
When you are very good in engine engineering and have all the
tools you can try to find some more horsepower in your engine,
but you always pay that with some more heat produced, which is
not at all good for our old BMC engines.

You may be right. Not sure.
Actually I thought that the gap was determined by the car=E2=80=
=99s
manufacturer ie one could expect to find the same plug in two
different cars and to find that the recommended gap was not the
same for each car.
Likewise, the BMC manual suggests Champion plugs at 0.024=E2=80=
=9D to
0.026=E2=80=9D and that was some 60+ years ago. I=E2=80=99ve al=
ways been told
that Champion plugs aren=E2=80=99t the best in the world and I=
=E2=80=99m sure
that a modern NGK can stand a little more heat than the
Champions that were around 60 years ago.
Anyhow, I=E2=80=99ll keep an eye on them. I=E2=80=99m a pretty =

there won=E2=80=99t be undue stress under the bonnet.

Spark plugs are designed and tested to be used with the gap
given by the producer of the spark plug.
When you widen the gap the plug gets hotter as it is designed
for and the electrode can melt or wear very fast.
Its a very short win you gain modifying them.
I never understand why people think they are better engineers
and know better than the designers of the system they use.

I run my MkII BT7 on NGK BP6ES which were recommended by some
of the wise ones on this list.
The car has a =E2=80=9CSports=E2=80=9D coil and a 123Ignition d=
istributor. DW
fast road cam=E2=80=A6etc
Now, talking of =E2=80=9Crecommended=E2=80=9D, the rolling road=
guys told me to
set the plugs at 0.028=E2=80=9D and pooh-poohed anything bigger=
when I
suggested that I=E2=80=99d heard of much greater gaps with my
approximate setup.
So, I went with 0.028.
The other day, I decided to experiment and set my spare set at
0.032=E2=80=9D. Same NGKs, no mileage on them..decent plugs. An=
yhow, it
made a very surprising difference. All round performance is
much enhanced.
Despite it=E2=80=99s 3:54 diff and 28% OD, it was never sluggis=
h on our
local hills. But now it fairly zooms up them.
To be frank, all a bit of a surprise.
Not boasting=E2=80=A6just putting that out there in case anyone=
else is
thinking of going up a few thou=E2=80=A6..
When I asked about gaps a few years back, some of the
suggestions were near 0.040=E2=80=9D. Surely that a bit much?
