Someone IS using rx7 plugs, I remember RG said its ok to use 7 plugs in 8s. Actually u know what, I wonder what will happen if I put these plugs into my 8.
9 leading
9 trailing
it wont "blow" my Renesis I think. what you guys think? should I be the "brave" dude and give it a shot ? :O

Since the casting thickness for the spark plugs is the same between the Renesis and other rotaries, I don't see why there would be an issue. On RX-7's I actually remove the spacer washer from the plugs to get the plugs right up against (but not touching) the chamber!!!
The best, most reliable plugs I have found to use in rotaries, including the Renesis, is the RX-7 plugs. BUR-7EQ and BUR-9EQ. If you must have platinum, add the letter "P" to the end of that number. They are less than $2 additional per plug for platinum and the standard plug is only a few bucks itself. Don't waste your time with the HKS, Greddy, etc plugs. Only buy the NGK plugs. You can get them at O'Reilly. Don't even use the Nippondenso plugs that Autozone sells. They don't last as long.

So RG, are you saying the BUR-7EQ and 9EQ are better than the RE7CL and 8BT?
Or are they preaty much the same?
As it stands the RE's are 2x as much as the BUR's.

Just install them like you would any other plug. Scott uses them on his turbo RX-8's. You won't notice a difference in performance but your wallet will thank you. They are totally different looking plugs from the stock ones.

I think the stock ones are Iridium. I'm not sure. Whatever they're made of, they aren't any better than the RX-7 plugs.
I'm just not one to believe that one plug is responsible for flooding engines. That's a tuning issue combined with the fact that the ignition system as a whole just plain sucks. Then you've got the original starter. What a slow turning piece. There are many things that contribute to flooding issues but I'm not willing to claim one heat range different on spark plugs is going to do it. That shouldn't even matter.

hey abbid, was your starter and battery changed? I had to have mine changed earlier this year cause she wasn't even trying to start. Flatbedded and carted to dealer for replacement (that day sucked).
If what guys say is true, I think I'm going to pick up a set. I'm about due for some more plugs.

Hey RG, if the factory iridium are supposibly good for 35k miles (per Mazda), how long have you run or going to run the 7's plugs? All based on a N/A 8 of course.

Go to http://www.ngk.com/
Based on their website, our plugs cost $19.95/plug + s/h..so..way below $35/plug...for 2 Trailing plugs & Lead plugs, that totals to $80 + s/h..add that to how often we change our plugs..that is like $26/yr if you do 10k/yr and change it out every 30k..
