I changed my plugs at 30,000 miles, which was ahead of the 37,500 maintenance schedule. They could have gone longer, as the gap was still within factory specified limits, color/carbon wasn't bad, and running quality & fuel mileage were normal. I don't see anything to be gained if I had replaced my plugs at 12,000, 24,000, 36,000 miles...

1.I get better mileage/performance by renewing plugs earlier as many do here.
2.Much depends on "how" the individual drives their RX-8.

A) If they were new plugs you should be able to just clean them.
B) Using commas instead of spaces and periods makes your post a bit hard to read.

uh--you may have your plug wires on backwards. the end that has the metal showing is the one that goes into the coils.
I have had excellent results of cleaning these sparkplugs with a small ultrasonic cleaner I picked up at Harbor Freight. I use straight vinegar.
They come out like brand new and run like new too.

Hi guys, so y'all are saying those are better than the NGK Iridiums?
I was under the impression that the laser plugs were best for it. Is there data to back it up, or going by trusty butt dyno?

Oil on spark plug
I am a new member and unable to start a new thread, so that's why this is posted here.
My mechanic found a little bit of oil on one spark plug when changing them out during a tune up. Unfortunately he had a busy day and does not remember which plug it was. There is no noticeable issue with the car.
It is an 07 manual with about 58K miles. Plugs, wires and coils done at about 30k when I bought the car as well.
Would it be normal in any case to have a little bit of oil on any spark plug? Or is this a sign of another issue?
Any help is appreciated.

Read this on why you can't create threads: RX8Club.com - Announcements in Forum : New Member Forum
(You CAN create them, just only in certain areas of the forum)
Oil is injected into the housing for seal cooling and lubrication. A bit of oil on one plug is nothing to be alarmed about.
You are just about due for new coils, plugs, and wires. All 3 sets should be changed every 30k to prevent cascading and expensive failures. See the new owner's thread for more info.

40th anniversary Edition
I know this a bump of an old thread, but some who search new posts might read this. I also switched to the Denso racing plugs and I am getting better performance and mileage. Hey I have used NGKs for years, but the Denso are better performers for spirited drivers.

plugs at 30k miles
I found this thread and it looks like "brown" is good. I just wanted to get your opinions on my plugs at 30k miles. These are my second set (unfortunately didn't take pics of the previous set). My car has 70k miles on it. I noticed that the leading plugs had more residue than the trailings ones. Is this normal? Let me know what you think. I appreaciate the feedback. Thanks!

Can smb please read my plugs? For 2 days ive been looking at pictures of good/bad spark plugs and still dont quite understand it - the middle has to be brown, or surroundings as well?
Just to add, I did seafoam of the engine recently and forgot to put in back old plugs.
These ones are only 6 months old (1500km)
Mine are looking like this already after cleaning them:
