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 new set of B6ES out in the garage from before the heads were converted to 12mm. I am not sure why I ended up going with a colder plug. Before I put classic car insurance on it I used to have to pass emissions and the HC was always too high. It always runs between 275 and 300 degrees and the plugs are the right color so I think the plugs are close to the right heat range.
I have rounded up all of the parts to convert it back to injection. Never did it because it runs so good I am afraid of loosing performance and reliability. |
