Yea i have about 30.5k on the car. Since I'm not too tech savvy with cars and don't know how to do most things... But if I buy this would it be better if I take it to a shop that has more knowledge on rotary engines or is it simple enough for any mechanic to do?
If i can install it... You can install it =) It really wasnt that bad.
Definitely change your plugs, yes we know that they are meant to last a lot longer and they do, BUT, they do not perform at max capacity, IMO , I did mine at 20K (12K miles) and noticed a difference once renewed.
At 12k (miles) my plugs were close to the recommended Max Gap limit, which for memory is 1.4-1.5mm...there is a slight difference in Min/Max electrode to earth plug gap for leading and trailing plugs, I would have to fish info out from my other PC if you want exact numbers.
But YES, mine probably would have lasted much longer,,,BUT..
IMO new plugs are a better investment for S2's and ANY rotary.
I just installed the BHRs at 20K (12k miles) on my VR S2 and tested the setup with original spark plugs compared to new plugs. I would definately have to agree that with the new plugs the idle was silky smooth.
The ignition system however, did help to alleviate some rough idling pops and burbles when in use with the old plugs. My plugs were quite worn similar to yours ASH.
My coils also showed large white rings
Thanks Charles for a great product. Idling is so silky smooth and butt dyno suggests a little more oomph at the bottom end

Reason: Series 2
So was there and clarification on whether the s2 coils are better than the s1 coils?
People that have installed the BHR kit on their s2's and have said they've noticed a difference does help, but like one person said, when you're expecting or anticipating "a difference", you're going to self consciously notice a difference.
The only thing I want to know is if the coils on the s2 and better than the s1 or not and if they should still be replaced around 30,000 miles or so.
The other thing is, the BHR wires, from what I have read, are custom made MSD wires that are included in the kit. And you cannot use factory wires or other OE "aftermarket" wires with the BHR coils, correct? Granted wires last, for the most part, a long time, if you need to replace the wires, you have to buy replacement ones through BHR? (or make your own at least)
Just got my 09 r3 a little over a month ago and has 41,000 kilometers on it right now, and my CEL has flashed a couple times. Although I think it is most likely my spark plugs, keeping the BHR kit in mind so I just want to clarify.
Ok, that's nice to know that you don't absolutely have to run the BHR wires, even though if I buy the kit I will. Just assuming the BHR wires are just thicker than the OEM wires.

They are not only higher quality wires, but they have the correct boot ends to connect to the coils. Take note that unlike OEM coils which have a plug in type boot, the BHR coils have more of a slip on type boot (the coil itself has a pin inside)
For those asking about power increase. I can say that in my 09 MT, I regained 5 hp after installing the BHR kit. Did coils, wires, and spark plugs all at the same time. It's not a huge difference, however is dyno proven.

Probably the plugs did more of a difference, BHR coils will give you a better response and will tend to keep cool when abused on constant operation, but I dont beleive they make any power difference, they will prevfent you from losing power from overheating coils, but will not give you power.
Hence my "regained" 5 hp. When initial dyno was done my coils were arcing. Rotary Performance pulled my stock plugs and validated. Not trying to say BHR coil kit will get +5 hp, just saying in my instance I did see a 5 hp difference before and after.
I have a 2004 RX-8 Manual GT and I was wondering what ignition coils lasted the longest and how long they last.
This can be a fiery topic...
Either the latest "C" revision oem coils if you can find them, or the BHR kit. Reading up on it, the BHR kit sounds like it should be the longest lasting, but it is 2x the price. It also works with the stock ecu tune, but can be optimized by tuning the car (some people will tell you it needs a tune even on an otherwise stock car but I would trust BHR on this).
BTW, since you have an s1, you should be looking in the s1 section of the forum and it seems more likely the BHR kit will outlast even the latest version of the oem coils on an s1.

"some people" have nothing to gain by relaying to the forum their experiences either . Whilst BHR ...............................
Installed the BHR coils and wires on my 2008 40th Anniversary edition RX8 at 40,000 miles. A few thousands miles earlier I already had installed the higher performance Nippon Denso plugs, which made a noticeable improvement. With the BHR coils and wires installed there was a very noticeable additional performance improvement. Faster throttle response, smoother revving and even a slight gain in gas mileage. I would recommend replacing the coils, wires,plugs, all at the same time. BTW did some research and found the Nippon Denso plugs gave better high rev performance ( they are used by many RX8 racing teams) and are more resistant to flooding problems. Got them through my local Advance Auto store, and they were much cheaper than price of stock NGK plugs from a dealer.

I installed the new setup on my S2 in May. The new design makes it much easier to install than older models. Took me about an hour I believe but I was meticulous about making sure I had the right plugs in the right spots which involved checking and rechecking a few times. Car pulls with more ease now. Gas mileage is still terrible. Idle is smooth.

Please take a few pictures of the new BHR setup. I would be very interested for my S2 on my upcoming coil/plug/wire change in 2020. I'm running C-coils from MazMart now ever since 41K. Mileage - expected to be worse than an LS.
They mount just like OE on the OE bracket and use the same OE-style plug wires too. Pretty much a direct OE replacement unlike the D585 ignition. $400 for four coils only though, but with a 5 year warranty
This coil improves upon and now replaces the previous Black Halo Racing Ignition System. Here is how;
1) No more external brackets are needed.
2) No more conversion wiring harness.
3) No more special D-585 style spark plug wires are needed.
4) Improved output performance versus previous offerings.
5) Will not illuminate Coil Communication CELs in JDM applications.
6) No need to modify the S2 bracket as needed with some other coils.
I had the new BHR coils installed a few months ago, and they are super. I had the older BHR kit for ten years and they were solid, but just wanted the newer kit going forward. They do last a very long time, worth the extra cost over OEM IMHO. Cheers
