Ok so I changed my coils from O'Reilly s carries a life time warranty. My 8 runs smoother but I'm still getting a code when I am at high RPMs for a misfire in cylinder 2 So I', guessing its One of the trailing plugs I changed plugs and wires as well. Oh and one of my trailing plugs was missing the back of the plug and I think thats the one that is misfiring one. Anyone heard of anything like that?

Just FYI - if the terminal or insulator on a plug are damaged, or in your case missing, it can lead to a bevy of ignition issues. It can cause signal/connection disturbances that can in turn damage coils and other electrical/ignition components. Good, clear signal is very important, which is why people spend money on quality insulated spark plug wires.
I don't know enough about the RX-8 ignition system yet to comment on what degree its components are susceptible to signal interference damage, but it would not surprise me if that could be happening here. So even though you replaced your coils, your bad plug(s) could have damaged them again.
See the attached picture - what, specifically, is missing on your plug? Picture of your plug would be helpful.

I used NGK Plugs and Wires and Oreilly brand OEM Coils. I have only driven it a few times because I bought it in Jan and I live in Northern IL and this is one of the worst winters since the 80s. I am going to get the Black Halo Racing coils but my car had a huge loss in power do to one of the lead coils going out. So before I invested 50 hundo on coils I though I might get some cheapys just in case I need to spend my funds on an engine rebuild. Plus BHR didn't want to do any discounts so no hurry to spend 500 bucks. One thing did happen I broke off one of the bolts that holds the coil down the same one with the broken plug. So I'm thinking I may have broke the ground for that but I thought the plug is grounded by the engine. But I could be wrong this 8 has throne me through more than one loop since I've gotten her.

Just picked up my intermotor coils from ogdensburg. From what I can see they look the same as the pics of oem coils that someone posted on the first page. I'll get some pics up tomorrow, and I'll hopefully be putting them in the car this weekend and let you guys know how they fit. The total bill was $188 for four coils, 4 plugs and also two oil filters (which I bought to bring the bill high enough for free shipping :P ) This was from advanced auto parts. Hopefully they fit and if so I suppose we could say that these are the cheapest trusted coils? Assuming they last! If they do then I don't see any reason to go and spend $500 on bhrs unless maybe you are building a track car or have some other reason for ultra high performance ignition.

hey i hope these intermotor coils work out for you and are reliable. But you miss the point of the BHR coils. They are not just for a track car. You will get better street performance out of them every time you drive. They have a hotter, higher voltage spark and you WILL notice the difference at all rpm, but especially at higher rpm. And they will get you one or two more HP and one or two more mpgs per gallon of gas. So over the long run they will save you gas money, give you more hp and fun and they will last the lifetime of your car. Any RX8 owners who have bought and used them would never go back to any cheaper trusted coil just to save money on the front end, when with the BHR coils you will save you money in the long run and the BHR coils will last the life of your RX8. I have used almost every kind of coil made for rotary engines for street and track duty over 4 decades, and these are the best I have found for any RX8.
I realize this thread is about the cheapest trusted coils, so don't diss me RIWWP lol.
Folks should get the coils they are happiest with for what they can afford. . I just wanted to put some perspective here about true savings over the long run.

You can resell BHR. Stock you try to resell them and you'll get laughed at. That being said I would suspect they keep most of their power for most or all of their life.

BHR's hold strong past 100k. I don't know what the longest someone has had the kit on for, but i haven't heard of a single replacement needed outside of coils that are defected out of the box, which is still very rare. Ray says that it is a less than 1% defect rate, and i have no reason to believe that it is inaccurate. He has sold over 2,000 kits, and i haven't seen more than 8 or so people find a defective coil.
BWD is cheaper for less than about 90,000 miles. Past that, BHR is cheaper in the long run. When you add in the possible problems from a coil failure that can be very cost, BHR is the clear winner. The upfront cost is hard for a lot of people to fork over though, I never had the cash all at once for a kit myself. BWD coils are fine for the first 20k or so, just be prepared to replace them regularly.

You don't get it, a failed coil and/or wire can lead to damage to your engine and improper fuel combustion can start problems with your cat. That warranty on the cheaper coil won't mean much for the costs to fix or replace a damaged engine or clogged cat. . By the time you diagnose that bad coil and pull it and go fight for your warranty, you may have started damage to your engine or cat. Besides the cheaper coils won't give you the performance or mpg bump that the BHRs will. There is a saying Pennywise and Pound foolish. Why fool around with declining coil performance every 20,000 miles and replacement by every 30,000 miles when you can have better performance and mileage for the entire life of your car. I know of NO one here who has worn out a BHR set. And yes they sell used for almost as much as new because folks know their performance, reliability ,and longevity . If you must go cheaper than so be it, but for my money that choice is simple and once you drive with the BHRs you won't ever want any other coils and wires, there is that much noticeable difference.

If money is no object, then by all means the BHR coil kit is the way to go. But the OEM coils with a lifetime warranty can be switched out every 20k miles to be safe, for free. For me, that's less than once a year, and it doesn't take much time at all. If I wanted to spend the money I'm sure BHR are a better solution. But I don't.

And don't get better performance , have more fun, and get better fuel economy out of your RX8 either. Ultimately its your fun and money. You have made your choice. BTW if you try to switch out the coils every 20,000 miles and they don't show failure, good luck with that warranty !
in the business of selling parts also, if you don't follow your suppliers rules then they will simply start charging you for the replacement parts or cut you out of the loop. if a coil is warranteed against failure then it must be failed before a warranty claim can be filed for the part, if it tests good then you will be in question. out of 4 coils on a car and you warranty all 4 in repetitions then who is going to continue paying for those replacements?
think BHR with their warranty would do the same either? if i were them i would test them and send back any coils that tested fine, because their supplier isn't going to dick around with them if they play that game either.
what i'm trying to say is you might get lucky and get a whole set of coils and you may not if the store actually follows their policy. the only thing keeping that boat with a hole at the water line afloat is that most parts chain stores have no way of testing the coils so they take your word for it, if they lose their contract from the supplier though then the boat blows up before sinking. basically it's just taking advantage of a loophole. parts chains don't require the part to be tested before offering a replacement, which is sort of idiotic if you ask me. customers should be held at least partially accountable for faulty diagnostics.

Honestly I do not know, but they ran fine on my car with no modifications. When I later raised the Dwell I noticed no differance.
No offence meant to ray, I have a hard time believing that a company as big as AC delco is making custom coils for probably 1000 to 1500 units a year.
I've also seen several threads about DIY d585 coils and have not heard of problems from those people.
