spark plug recommendations

[tmctguer]

i have a '73 911E 2.4 MFI. does anyone know of a good recommendation for spark plugs for this car ?

what about spark plug gap?

Try some NGKs ... for hot weather -- B-8ES, for cold weather -- BP-7ES.
Gaps from 0.028" to 0.032" work well.

I remember reading in "Up-Fixin" an article someone wrote recommending a colder plug when running track events, the use of which will result in lower engine oil temps. I'm not to sure about this, anyone have any knowledge/experience with this?

I've found the Bosch Platinum Plus a very good performer, they last a long time and are pre-gapped.

a parts place gave me a NGK part number of B7EVX. has anyone heard of this plug? is it the same (or close to the same) as the B7ES or BP7ES ?

i would hate to buy and install the wrong plug !

According to this chart (Adobe Acrobat viewer required):

http://www.ngksparkplugs.com/techinfo/spark_plugs/partnumberkey.pdf

The "S" in BP7ES means "standard 2.5mm electrode". The "XV" in B7EVX means "high performance platnum"

In both cases, the "E" is the length of the threads.

The other difference appears to be the "P" which is shown as "projected insulator type", whatever that means.

For what it's worth, the NGK page lists for my 82 SC, BP7ES for standard plugs and BP7EVX for platnum plugs.
