So it came as a surprise that my car has 12mm plugs. I thought all 914's had 14mm? (IMG:style_emoticons/default/confused24.gif)
The PO was using NGK DP8EA-9. Looks like they have a pretty high heat rating at 8. The 14mm plugs most people seem to recommend, and that I used on my old 1.7 are the NGK BP6ES, which have a heat rating of 6. Should I be looking for a similar rated plug for my current car? It's a 2270 with Mallory Unilite dizzy, MSD 6AL, and MSD Blaster 2 coil. Is there a better plug for my setup than the DP8EA-9? |

I have a 2056 with 12mm plugs, Mallory Dizzy with an Igniter II conversion & low impedance .6 ohm Igniter coil.... Dellorto Carbs. The plugs I am running are NGK DR7EIX Irridium. The car seams to start easier cold and the idle stabilizes faster than with the copper plugs. Other people will tell you not to run anything but copper but in my opinion with a hotter ignition you might as well run a plug that doesn't constantly wear out.

If so, how long did they typically last for you? |
