Hi I would like to know what is the best way to clean spark plugs e.g sandpaper, wirebrush, using a lighter ??
I have been through 3 sets of spark plugs in the last 6weeks on My S4 Rx7 GTX its pissing me rite off.
Any info will help.

 

Hmm... What's wrong with them? Carbon build up? Wire brush would probably be your best bet. Or maybe run some carb cleaner through the engine to get rid of carbon buildups.

 

if they are fouling that fast, then obviously something else is wrong with the engine.

 

Maybe the engine is running too rich? What kind of deposits are on the plugs?

 

yea I second the engine running rich and the plugs being drenched with fuel and fouling.
