What spark plugs to use.
 

Hello,
I have a 82 RX7. my setup is a MSD6a box direct fire with 2nd gen leading coils. Trailng is stock.
My question is what spark plugs should I run on the leading and what should I run for trailing. My primary use for this can is city driving and occationaly a few tares down the roard:) I really want to stick with NGK.

I ve read that the BUR7EQP are good for leading???

run FC leading and trailing plugs. they are pocket items at junkyards

wacky ever time you talk about junkyards you make it seem like the yards in LA are full of rx7's. last time i seen a rx in the (jy) hear in new york two puerto rican guy's arguing who gets the transmission.... :lol: + on the fc plugs..:icon_tup:

I will only run Denso. But, I run Wasted Spark.

when i lived in SoCal (about 45 minutes away from LA) all the scrap yards around me had rx7's pretty much constantly. but yeah, FC plugs are good. Every time I go to any scrap yard with 7's i nab all the plugs. i have about 8 sets of fb / fc plugs.all of em' have been cleaned and tested to work :D

I only get NGK's or Denso's from scrap yards, though. autolites and other brands are cheap enough i wont bother to grab them there.

actually, you are correct. lots of S3 and S4s, old school and S1-S2 every now and then. Wish there are more old school RX like in the 90s

your lucky..it sunny everyday junkyards are full of rotary powered cars....the good life.
