Spark Plugs

[cobra 53]

I`m looking to replase the Spark Pluks on my SBF 302 / 1994.
Engine is equiped with NGK BPR6ES11. Nearly each Plug shows a different burning face.

Some suggestions about new Spark Plugs?

It sounds like you have more of a fuel delivery problem, if in fact there is a problem. Its hard to get a complete even burn on higher hp engine. I rund Autolites but would prefer NGK's. How different are the plugs?

In the fotos you can show the plugs some minutes after take them off from the cold engine.
I hope it helps to give me a hint.

First off im not an expert and its kind of hard to tell from the photos but i dont see anything glaringly wrong with them. Im sure others with more knowlege can chime in, is it running poorley?

Better fotos.

Car seams to run well on ordinary highways. No coparisons, as it is my first V8.
Some times after stop the hot engine, it has one or two misfirings. Mostly after driving in town.

I honestly dont see anything wrong there.

I don't think you have problem with the plugs so much as a tuning issue. Hard to tell from photos but looks like you are running a rich mixture or the engine is using oil. Could also be a plug that is to cold. I am using autolite 25's and not a problem.

My all time favorite plugs are the Accel 714 plugs. I can't always get them from my local speed shop since I may be the only one with an FE that uses them. So sometimes I may be running the Autolites as mentioned above. My plugs will look a little dirty if I don't get on it a bit before putting it away for the night.
