Interesting point about the 5W-20 oil, oldtimer2. When I had my 8 in for routine servicing a couple of days ago, I raised the matter with the service manager. He was clearly aware of the issue but was too cagey to indicate the degree to which he thought it significant. Could I ask how you know that Mazda outside of the USA (and Canada, by the way) recommends 5W or 10W-30 oil? I have attempted to find a reference to this but my Google searches only come back to your own messages. I am not meaning to imply that your are making it all up but if we are to make progress with Mazda we have to have stronger evidence, I think.

I would like to know where you bought your p[lugs and if you installed them or had it done for you. I am in the same boat, I have 2250 miles on my car 2006 Shinka Edition, (Don't drive it to often) and after oil changes and recall items I have noticed a considerable drop in acceleration. I would like to know what plugs you purchased, how many? and what is the difference between leading plugs and the trailing plugs and again what is the best plugs to buy. I do live in the Pacific Northwest 70 Miles North of seattle. Any assistance you can render would be a great help. Maybe I would drive it more often if I can get some more pep back in to it.
Thank you M.Murphy

Replacing plugs on the RX-8 is not too bad. Just push the hoses etc. that are in the way towards the firewall. I use zip ties to keep them there. From the drivers side (left) you can easily reach the plugs once those hoses and cables are out of the way. The leading (lower) plug is a different temp range from the trailing (top) plug. This is because one is traditionally just a "cleanup" plug, though it's used for more on the renesis. You can order the plugs online, or from a dealer parts dept. There are now at least three heat ranges available. The hotter is good for winter driving. If you are down south, they wouldn't be necessary. Use the mid range ones for winter. The cold plugs are really only necessary if you drive hard in hot weather (or race). Also, the really "hot setup" is the iridium plugs. They last a lot longer and ignite with more reliability.
Be sure to apply antiseize to the plug threads (the copper type is fine for this application). This will make it a lot easier to get them out should you leave them in there for a long time.
Tighten the plugs until you feel the crush washer just start to crush. A torque wrench is the preferred method, but I don't think you can get one in there.

I took mine into my local dealer, per. recall, they replaced the plugs for free along with a free service. I did not notice a drop in acceleration.

Bryan102, your question about evidence that everywhere in the world except in the USA, Mazda requires 5W-30 weight oil in the RX-8 is easy if you are really interested in proving it to yourself.
This forum is probably like other forums in that I can not put links in my response to other web site forums where RX-8 oil required is 5W-30 weight oil. However, you can very easily "Google" for Mazda RX8 Club UK (United Kingdom), for example, and read their web strings and you will see that the oil used in the UK and throughout Europe is 5W-30.
The United Kingdom RX8 Club forum not only covers just England but all of Europe. You can continue your search for other countries and find that as I have reported the oil used through all the world except in the USA is 5W-30 weight oil and not the 5W-20 weight water Mazda requires us to use.
With respect to you needing stronger evidence, only you can prove it to your self if you want to find out.......good luck in either easily finding the evidence that is out or in trying to cause confusion about the issue because you might be a USA Mazda Dealer.

I followed the links in your (old) post, read the PIE info, and have a question regarding the PIE aux-in adapter. After installing the aux-in (these are RCA jacks?), where are they? I.e., where would you connect your MP3 player?

Sorry for the late reply, but I was not subscribed to this forum.
You pull the radio, plug the PIE into the back of the radio, you plug the PIE to AUX adapter into the PIE and than ends in two female RCA connectors. You plug either an RCA to RCA cable into these or an RCA (male) to mini stereo plug into these. Neither is supplied with the PIE but both are available through the places I linked, Radio Shack, etc. You then plug the male mini stereo plug into your MP3 player, sat radio, ipod, etc. It is just audio in only, you can't control the ipod or anything with it.
