Thread: Spark Plug question

I have a set of new NGK's, installed them once, because of a bad knock sensor it caused detonation and know the spark plugs are covered in black soot from the fuel burn, are they re-usuale know that I have replaced the knock sensor or is there a specific way to clean them?

what type of plugs? different material plugs burn differently and at wear out at different rates. also gapping has alot to do with this and if the motor has some type of power adder.

They are NGK BR511E's I believe and I gapped them at the stock setting of .033. I just wanna know if I can reuse them.

Throw em away. New plugs are $1.50 a piece, get them from Greg V.

Also don't gap them down. You seem to be NA (no mods in your sig), so .039 is best for that.

sounds like coppers. i thnk you mean bkr5e-11s. id just replace them as they are about 2 bucks a pop.

Replace them i will, thanks....
