What would the symptoms of worn or fouled out spark plugs be in a rotary?? or in a 3rd gen?



I know they're supposed to be changed like every 15k miles or so.

Shoot, I change mine out more than that. The car can run rough. You can hear ignition break up at high rpms. It can backfire more in the low rpms.

Basically, if you have any doubt as to whether or not the plugs are bad, just go ahead and replace them.

exactly what he said.



It largely depends on your mods and driving style. If you are running pig rich or drive like a ***** they will foul out faster.

Yeah, if you question them, might as well change em. This is he reason why I'm using the FC's spark plugs. They are the same as the FD's stock plugs, but copper. A lot cheaper, so I just change em whenever.

you can get them for $ 5 each at pep boys bur9eq https://www.nopistons.com/forums/pub...IR#>/smile.png
