fouled ngk spark plugs
 

so the other day i started sputtering really bad and i decided to head up to the local parts store and pick up some new spark plugs. i bought the correct one, two leading and two trailing. so i go home pop the hood and start replacing them one by one. come to find out that some idiot had put in 3 leading and 1 trailing. so thats not even the best part. all four were charred black and nasty looking. obviously fouled. i just thought i would share that with anyone who cares. i am a newbie to the rotary but even i had the smarts to do some research before i did even a simple task.

since ur dealing with leading and trailing specific plugs, i think fc. but seeing ur user id, i take it the car is an fd.

I am new to this----what is a leading and trailing plug?

wow, ngk any others better?

the spark plugs. a rotary engine has one leading and one trailing plug per rotor. have u not done any research at all on these engines? this should be of some interest to ya.

the vast majority of rotary owners use ngk.

Yep. Can't get much better than the stock NGK plugs. I get mine from rx7.com. I change them roughly every 10-15k miles. Rotaries love fresh spark plugs.

Could try a different temp plug, Racing beat has a good write up on spark plugs for the rotary.
