Mazda Oem Coils are crap! BHR Ignition I guess.....
#26
Yeah, I took my 8 to a local dealer (one that I hadn't used yet) to have some warranty work done on my tranny. The rotary tech was checking out the engine bay, "oh i see you went with that BHR kit, good choice!!"

Spoken like someone who has never been racing, and yet has racing as part of thier name? Interesting...
I actually run E-85 in my turbo FC (S6 engine) and I manage to get by on stock FD coils, no issues lighting off the mixture even as low as 8 to 1, so I guess we are OK. I also happen to have experience lighting off e-85 in several 800+whp 4g63's with stock coils and an CDI, soooo maybe it is you who need to do more research beyond "developing" an adaptor harness and slapping together a mount.
I do not care enough about BHR or your spiffy ignition to organize anything, I just was responding to a thread on a public forum regarding percieved spark issues in the RX8. You are the one making it about you. If there was a single advantage to using your coils, we would have them.

there isn't any, they don't even know how to check for defects. and if you show them the "white" spots (yea we all know its NOT an indication of the coil's condition), they won't even bother and just issue you a replacement (or refund, if they are out of stock)
I'm still enjoying my O.E. parts with Lifetime warranty, but hey I like to try new things, good and bad, so I might give BHR coils a shot in the future (probably next year)
why ? you never heard of "designed lifespan?"
you can design something that last 5 days or 20 years, it's all up to the OE's original request. Mazda did great back in FC days, their coils (made by Denso) were super humanity good and strong. but when it breaks it will cost you 1000 for trailing and about 5-600 bux for leading, EACH. Do you want that? what if its just "**** happens" and you have to buy a new one ?
FC coils cost too much when new, people complained, and its a problem for Mazda (warranty cost money)
so on FD Mazda "back down" on the coils(it was mounted at a crappy location, limited space, whatever), result? shorter lifespan but "cheaper" when new. Are people happy? I guess. somewhat. cost was like 160 bux each. oh yeah. but it fails much sooner than FC (3-5 yrs the most, compare to 20 yrs)
and this "backing down" on coils/ignition system is not just a Mazda thing, all other manufactures, domestic or foreign are being "cheap" on coils now.
Strangely, stuff I get from Autozone/AAP are usually Denso or whatever, you just need to know what you're looking for, and special order them when needed. You can't do that? that's your problem
*sigh* dont bother man, just don't.

Yes the FC and FD coils were more expensive but I'd rather have quality over quantity. U said Mazda backed down on the coils, so u agree with me that they are crap. I mean never have I seen coils that regularly fail around 30k miles and even earlier in some cases. Too me that's crap and even Mazda ended making 2 revised versions right? Yet, I hear the new ones still don't last much longer. Should I chance it or get something that is getting a lot of good reviews? I don't want to keep buying coils that isn't going to perform any better than stock, so I'm gonna upgrade. and get the better gas mileage, smoother idle & revs, slight increase in hp. It's a win situation getting an upgrade instead of losing money to replace coils.
I am not trying to be arguementaive, but would like to make a couple of points:
Mazda DID NOT redevelop or revise anything. DENSO, the manufacturer of the coils, made a coil to fit the stated requirements as given to them by Mazda. They manufactured a part that met the requirements. At some point it became obvious through warranty tracking that there was a coil problem. At that point either A) Mazda told DENSO it needed something better and Denso supplied them with what they asked for or B) Denso got tired fo filling warranty claims and issued a coil that it felt would live under the conditions and still fit the footprint.
Either way, the case is not that the coils are "crap", they simply are not up to the task in practical everyday use.
Replacing your stock coils with stock coils (assuming your engine etc. are up to par) will give you the results you want, and are inexpensive.
Also, driving your car as you should will do far more for you over the long run. You simply must redline the car at least once a day and preferably more often, as this helps to clean the carbon and schmegma out of the chamber and will lengthen the life of your motor, your cat, and everything attached to it. Drive in putt put traffic, short-shift, or be scared to hit the limiter and you will spend thousands in repair costs over time needlessly.

I actually have a set of ne Ngk iridiums, but I'm not going to put em in and get them fouled if the coils are not producing strong spark. I actually tested the front rotor coils right now with a spark tester and the spark is weak. I'm not even going to test the rears which have burn holes through em. 45k miles on originals also, should I question if the coils need changing? Not really.
#35
I would call them adequate. They do thier job. I guess having dealt with BMW/VW COP/CNP setups where its considered part of the service to replace the coils along with the spark plugs I have a hard time understanding the complaints.
Again, we race these cars and run them hard with no issues. 225whp NA, time after time. YMMV apparently.

Why not put a coil in that does not deteriorate over time and cause issues? Fouled plugs and clogged catalytic converter.
Why not install a coil that has better spark and longer life? A coil you would not have to worry about failing in 20,000+/- miles. Seems like the BHR coil is the logical choice for the RX8 compared to the options that are out there.
Why would you not want the best performing parts for your car ?

^ That is why I got the new coil setup. I have gone through 4-6 cats on my car. At some point you loose count. I now have over 70K miles and the emissions warranty is going away. I have to live with emissions testing here. I need to have a cat that will live and I am convinced that the BHR kit w/Yukon coils will provide this.

Honestly, we tested several different coil setups and none made anymore power or proved to "clean anything up".
Again, IF your parts worked and provided an advantage over stock, we would have them. I just havent seen it.

Oh there is a lot here thats interesting....
What is MOST intersting is you have not offered PROOF beyond internet legend your coils will do anything beyond lasting a bit longer than OE.
AGAIN- I TESTED, on a DYNO, several coil sets and not ONE offered any measurable improvement over new/good condition stock coils.
Attack me personally any way you wish, but AGAIN, if your product offered any advantage we would have it.

There is a TON of dyno info out there. It's not like we haven't been doing this for the last 3 or 4 years. Google is your (and our) friend.
We just choose to NOT make power gains part of the marketing. Is there something wrong with that? Somehow, NOT making a claim is criminal to you?

Let me ask you D Walker, what inspired this query about our coil system? Seems to me you have made up your mind already and don't want anything to do with them.
So what are you up too? Looking for a new market to work for your own benifit? Somewhere that nobody is familiar with you and your current reputation in the automotive aftermarket/performance world?

I have no issue with the stock coils under racing conditions, period.
We do however carry several sets of coils with us, both aftermarket and OEM.
We carry these because there is always that slim chance something will fail, and we carry spares. Just like we carry spare brake pads, calipers, transmissions, clutches, etc. It just does not work to NOT have spare parts.
I have tested several different coil setups on the dyno and have seen no improvement worth talking about.
*** I should note here that I have been looking for ANYTHING to legally add power to the car, including replacing the existing ECU with a true racing ECU, possible intake/header/exhaust changes, literally ANYTHING. I was pretty much told that with the stock longblock package we have to run there is no more power to be had. Period. But I tested it anyway. I could maybe gain 5hp above 8K with some ecu tweeking but thats it. There just is not anymore in our configuration.
SO with the above taken into consideration, I doubt ANY coil/ignition upgrade would have done anything for the car, so I may be being a little unfair in this regard, but given the assumed "weakness" of the OEM coils one would reasonably think that SOME gain, even a minor one, would be there. But no, there was none.
AS I SAID MULTIPLE TIMES- I dont care one way or the other, and initially only reported MY experiences, which I ALSO said may have no real bearing on anything. YOUR the ones getting bent about it and attacking me personally rather than simply representing your product, which is very interesting to me. Kinda like any opposing viewpoint OTHER than yours is wrong, and rather than simply bring the tech and show why you believe what you believe, you just attack the person of differing experience. Awesome. I wish you luck.
