Which Spark Plug for a 2.0?
 
The car is 68 911L with a 2.0 (130 HP not a T) and a MSD installed. So what spark plug should I use, I did a search and found varying answers. I was thinking the NGK BP7ES.

Bosch comes back with :

<b>W4DP0</b> O.E. SPARK PLUG 130hp Gap=.024

NGK:

<b>B8ES</b> Traditional spark plug-2411 Gap=.024


Not sure if the MSD influences selection.

What does the B vs. BP stand for?

My local shop has the BP7ES and 8 in stock, but no plain B's. Can I use the BP?

Bosch W250 P21 is the original plug for the car, call Gary Emory at Parts Obsolete in Oregon, 503 835-2300.

Tell him Eric sent you.

I know Gary, I just need some plugs perferably today. I may have go to a Motorcycle shop and get the B8ES.

Seems the P stands for "Projected Insulator Type". Not sure how that affects your application.

Thanks Rick! I found that chart on the NGK site as well, now I can figure out what a Projected Insulator is or go to a bike shop now? Bike shop it is.

The 'projected-nose' versions are generally more desirable than the standard version. Both are fully compatible with the 911 combustion chamber, but the projected-nose is a bit more foul-resistant.
