Glad i ran into this thread. i was looking into getting new plugs early next year.. i am on about 17K miles on my current set which was changed by the TSB and might get the FD set since they are cheaper and just change them once a year or so...

Really? I thought stock were Iridium plugs.
I think it's a new marketing package from NGK
Any feedback on Denso's yet?

Best thing to do is go to your dealership at about 30,000 miles with the complaint of "hard starting and running rough".
You'll get new plugs under warranty.

Ir reminds me of something that surprised me. I was at Indy one year watching a guy change plugs on a car in the garage. I saw him turn them in and I expected him to whip out a torque wrench and get them to spec. Nope, just gave then a twist and fired that 950 HP beast up.

$14.95 each!! These are the stock Iridium plugs.
I did a search on e-bay and got all four of the plugs that we are talking about(RE7CL & RE9BT) for $66.55 including tax and shipping. The dealer wanted $58 each, spark plug.com wanted about $90 for the four. I will be putting them in on thanksgiving. I have 33K on the trailing and 10K on the leading. I have tried all types of plugs in my seven different Rotaries and NGK are the best for your money!

So what's the difference between the "temp" plugs that ship with the car and the replacements when you buy it? Seems to me like the car felt better when I test drove it than after it went in for the plug change, which was somewhere around 300 miles.

Anybody have part info on the RX-7 plugs they are using? I'm thinking this might be worth a shot, since I paid $80 for my last set of stock replacements.

Crap.
Yea he sent me some messages with info about this. I thought it was a good joke.
Are they actually different plugs or stock plugs that get fouled due to many short trips before the car is sold? Because I am at 3k and the car runs great. I do premix with synthetic 2-cycle oil and MMO (1/2 oz total per gallon).
Guess I'll call the dealer and see what they have to say.
And here I thought I made out like a bandit by getting "free" plugs

I am not the expert, but I was told that they are a 'hotter' plug that will allow the dealership to make short trips around the lot without the fear of that flooding issue.
But again, I am not the expert. The dealer forgot to do mine, and I had to go back to have them replaced.

Just go to any auto parts store and ask for a complete set of plugs for a 93-95 RX-7. 2 trailing and 2 leading. Should be less than $30

The RX-7 plugs as good as they are will last about 20K. I just got stock Iridium plugs (OEM plugs that the dealer wanted $58 each) on E-bay for $14.95 each, and they will last 30-40K. Look at mesg #35 above. Why bother with changing the plugs twice and they don't work as well! I have put over 523,000 miles on rotary engines and tried every kind of plug and NGK are the best!

Hmm, I found Mazda OEM 6 heat range plugs for about 10 dollars each, 12 with Shipping
and about 9.75 bux for stock 7 heat range plug ... if you buy 10.
NOT BAD.
At this price, seriously, I think Im completely happy about changing them every year or so.
but funny thing is, no one sells Trailing plugs on Ebay? wtf ?
Im gonna order some and let you guys know how it goes.
