Pics of OEM spark plugs changed at 36,602 miles
I didn't think they looked too bad but the new ones are in there now. No difference in performance but I wasn't having any problems either.

I did mine today at 33.5k miles (still oem AFAIK).
2004 6 speed RX8.
Owned since new.
It run soooooo much better now. I did super flood it three times.. so I should have checked them before now.
FWIW- I found some at an area O'Reilly Auto Parts store in stock, and they price matched on line prices.

One jack stand and take the driver's side wheel off. Remove the little rubber cover for access and whoever recommended getting the wobble extension, great advice! I found this combo 13/16th spark plug socket / wobble extension at Advanced Auto today before the change. Worked purrrfectly. It's pretty easy Bub.
Remember: (L)ower = leading and (T)op = trailing plug. Also remember to get a packet of anti-seize and a packet of dielectric grease.

Where are the other two plugs?
And FWIW- I did super flood my car three times on these oem original plugs.
Does premixing help with plug build up?
And FWIW- I drive my car (once properly warmed up) like a hated step child.

All 4 of my plugs are identical. I run BUR-9EQPs (2 shimmed) in all four slots. That was a picture of one of my plugs against a new one to compare how much the center had eroded. From what I remember, all 4 plugs were similar though that one was probably the worst.

It's easy to do it using the jack from the trunk. Jack the LF and remove wheel, remove the flap with a philips head, get (3) long extensions and a socket/ratchet. It takes 20 minutes to do without rushing

I wonder how much the gap has changed in those 36K miles. Can you measure? I have found that these iridium plugs in normal use open up the gap very little.

Is it just me or does it seem kinda stupid to waste money buying iridium plugs when they can't actually be used for the life of the car because they'll foul in 30,000 miles? Why not just get platinums and save a few bucks on something you'll have to replace anyway?

I got skinny short arms, is that good enough? I have big hands though, and I keep bashing them on things inside engine bays.

I have tried them all, believe me. The OEM are the best for the money and can be picked up for $80 or less( I paid $56 for my last set). I love the "OEM" iridium plugs. One of the down falls of the rotary is how ruff they are on plugs. Now people are getting 35-45K under good conditions, some more if its mostly hi-way. Piston engines 100K no problem.
