Best spark plugs set up for Rx7 JDM RHD?

Bottom line is that the OP will be just fine using the stock plugs. With his current setup he's really not going to see any significant gains by upgrading to more expensive ones, if anything he may see a REDUCTION on performance due to fouling and difficulty operating at lower temperatures. (Edit: I'll break it down for you, since you seem a bit less aware - I spend a little over $30 for my plugs, PER PLUG! I use them because my engine build and power levels benefit from the stronger plugs. If I were spending $130 on plugs with a mostly stock car it would be a stupid, stupid, waste of money and the plugs would foul almost instantly and be less than useless. At stock levels you're only going to need the basic plugs that run you about $15 for all four.)

Perhaps you should do more homework before throwing arbitrary quotes and sayings out there simply for a post count.

I have never used a forum before, and RX-7's are the only thing in my life worth forum'ing over...
sorry, but, my post count feels good bro. =) .


I just smoke cigarettes.

Now your beating a dead horse? Your signature with all that silly drifting/JDM bullshit takes up more room than most on-topic posts. Maybe being vaguely on subject and speaking in stupid half-baked platitudes works for you in real liife but it's just annoying on a technical board. The OP asked about spark plugs.

When it comes to plugs it is all personal choice. If you are planning a daily driver with a weekend racer have 2 sets of plugs.
1. A colder plug for (track/racing events) where the engine is keeping higher revs and can aid from the benefit from the plug.
2. A milder plug for day to day driving (what ever the man. rec.)
Also keep in mind power adders as well, super/turbo charges, NOS, ECU tuning as well.

The only plugs I avoid are ones with small electrodes. (IE Bosch plat. series plugs.) Personal experiance has taught me that one. 1 small piece of carbon lodged in the electrode and caused a missfire.
Also try different gaps as well when switching out plugs each engine and tune is different and the car will respond differently based on fuel burn and tuning.

Honestly I think he's just doing it because he's trying to "contribute" (aka, build his post count) despite the fact that he really doesn't know what's going on. The majority of his posts on the forum thus far have been empty 1-liners fapping to another persons car, talking about "JDM" (yo!) Stuff, or saying hello to new people.

I think he's just hoping that speaking in generalities gives him a better chance of sounding like a good source of knowledge. ----> "I will break it down for you less aware people..."

That's a good point and not a bad idea. It's just too much of a pita for me though, lol.

Hi, there

Thanks again for your help... I'm gonna get 2 x BUR7EQ and 2 x BUR9EQ

1 more question... having coolder plugs could be the reason for popping?

sometimes when i start my car at idle it pops... and when it's warm and im back to home... when im parking, and releasing the accel... it pops sometimes 1 or 2 hard...

I don't think the popping is due to plugs, I believe that is more from richness in the tune/stock ECU. If I remember correctly I had something similar when my car was slightly modded, but that was a while ago so my memory is a bit fuzzy =( I'll conceide to the judgement of somebody a bit smarter on it than me on this one!

Just to clarify though, you're talking about just light pops and burbling, not backfires or flames, right?

I agree that 7s and 9s are fine for a stockish configuration on a FD. IMHO platinum plugs are a waste of money on a rotary, the BUR7EQ and BUR9EQ is fine, just specify a 1988 Mazda RX-7 if you're going to an auto parts store.

A plug that is too cold for your driving habits will foul out quicker and this will lead to harder starts, poor gas mileage and a reduction in power. Exactly what do you mean by popping? Loud bang, light pops, flames?

Hi, there...

well I've made a quick video to show the pops...

it's not a cool start.. it's a startup after 3 hours...

P.S. I don't know how to add videos so please check the above link!

thanks to all!

I don't know...the sound quality (my computer and/or the video) isn't great, but I really didn't hear anything all that unusual.
Your idle seems high, and what I heard was just the normal small random misfires on decel that in my experience are typical. Much of that is probably always been there from new, but the cat-back doesn't "hide" it as well as a stock cat-back muffler. And if your plugs are colder than stock, some of that might go away with new plugs....maybe new wires.
