BHR ignition on S2's
 

Not about fitment but more who has done it on the S2, your thoughts on the before and after.

Basically before i get the kit i just want to see people that have done it.

*waits for Team to bitch about something*

I dont have the BHR kit per-say, but I did a DIY solution using similar parts. The BHR will fit just fine, and as far as before/after, you can feel a bit more throttle response, and I got about 1 mpg increase under similar road driving with 2 consecutive fill ups. Not sure exactly what you are looking for, but I honestly think it is worth it considering how quick the stock coils go to shit.

@ about 30k and its my daily so im trying to take care of any weak spots before it is a big issue and just want to hear what people have to say both positive and negative.

I have the BHR s on mine .... you'll notice quite a difference in throttle response . I didn't notice anything as far as gas mileage but then again Not something i paid much attention to anyway as I only drive it here and there, not my daily driver. Def a nice upgrade !

If you have not done so I suggest you change your Spark Plugs first, then see IF you notice any difference, I do when I renew my Plugs earlier than suggested by Mazda and I have OE Coils.

BHR make very good products.

You won't feel much if anything from the BHR kit. IMHO, the biggest reason to purchase it is for reliability and better sustained performance over time. They last longer and performance won't degrade as quickly as the stock coils.

Doesn't mean it can't run better. It's not required but I'd seriously consider changing your coils if you have over 40k miles on them. It's not fun when one of them fails. Before I got my BHR kit (on my S1) I changed mine every 30k miles. Believe me after a few unexpected coil failures and being stranded on the side of the road it's worth it. Also, the performance of the coil degrades over time. You're likely to feel the difference too.

Also, change your plugs every 18-20k miles.

Your Series 1 had the old (original coils), updated coils from Mazda were not installed until the very last of Series 1 (2008) and then Series 2..which BTW this thread is about.

99.98% of Series 1 RX-8 owners had the old stock Coils.

I am not going to disrespect BHR's product as they are a vendor here..

Degradation does happen to Spark Plugs, and frankly every one who raves about changing their stock coils also change their Spark Plugs at the exact same time...so what really was the improvement here in butt dyno..was it the new Coils or was it new SP?

Do we really know whether or not worn Spark Plugs degrades the stock Coils?

MY 2009 fires up as well as the day I bought it, stock (latest) Coils.

In other words I have not yet seen Coil failure on Series 2 RX-8's.....yet.

How many miles Ash?

This is the answer i was looking for thanks ASH8, I am about to hit 30k in my S2 so i am going to do the plugs yes, just wanted to see if i should worry about the coils yet.

Don't really feel like getting stranded in baltimore lol

I'm installing BHR coils this weekend. Cheap insurance. I'm not exactly driving a detuned small block chevy here. Then again, I also premix on the S2 so maybe I'm just really paranoid...

I will post whatever I want to thank you..you do not own this thread or forum, and you sell a coil product here.

I am simply stating that there has not been a rush or many if any Series 2 COIL failures...perhaps you can re-direct me.

As I said the last and latest iteration of Coils came out from December 1 2007, so there would be about 50-100 Series 1 RX-8's with late coils in them, if any.

Production of Series 1 stopped in January 2008, February 2008, March 2008 no RX-8's manufactured, April 2008 the Series 2 started production.

Seeing you are the expert Ray, how many N3H1-18-100B's have actually failed?

I have 43,800 miles on my SII and have not replaced my coils and it strats up just fine. I can tell you that I am on my second set of plugs and each time I change them, I feel the throttle response improvement. And, thanks to my Kenwood 9980, the last plug change, I can say that I saw an increase of .8 MPG (that is point 8) increase from the plug change alone. This is based on about 6 tanks of gas prior and 4 or 5 after the change.

I drive 70 miles a day M-F and about 45 miles total on the weekend as this is my DD.

I've been running the BHR Ignition Kit on my '09 RX-8 for the last year and a half. My main motivation for the upgrade was track use and the slow degradation of the OEM unit which might not be very noticeable (much like shocks wearing out).

Not much to report though, the kit works great and it's one less thing to worry about when getting ready for the next track day. This to me, is worth the cost (simplicity in life is great).

So to be certain... No reported failures, but because it happened on the previous series, using a different part number, most notable on high horsepower - beyond NA limit applications (the same series that flooded), I should pay the cost of 1/2 a years full coverage insurance for this, not yet needed, not yet probable, but "possible" upgrade. Hmmm. I do believe they are a great product from reviews and at some point I will own them, but I fail to see the justification to imply it's extreme superiority or necessity given 3 years and no failures of the stock part(s). After all this isn't a performance mod, it's a "reliability mod". So far stock seems pretty reliable.

Well if it makes you feel better i still premix as well.

FWIW, I've had one of the 'new' OEM coils mentioned in this thread fail on my series 1 8.

im at 64,000 on stock coils on my '04, with exception of 1 i replaced at 58,000.
but i got bhr coming in the mail sooon

Stock, after the original Version, is pretty reliable, and Version B makes it even more reliable, and that's already 2008.

now Version C coils, Mazda specifically state it on ur latest car(Spirit-R), usually unless they made signifincant changes they will never mention it, but they did, and cost for it has doubled, might be just an exchange rate thing + Mazda markup, but I guess they probably told Denso (I think they're the supplier?) like "Look, Just make that shit as reliable as you can, We have 200K RX-8 out there, market is still ok, and we need to make Rotary look good so our next one will sell, so yeah, just make it better"

The coils I have, Version B, gets Lifetime warranty, its not on OE box, so? does it matter? for 100 bux. I'm more than happy about it. Even if I have to buy Mazda boxed coils, cost only 200. and last set I have had maybe 20-30 K miles and it was Version A, not like it gave me any problems but I just swap it with Version B, Lifetime warranty so why not ?

You do know any electronics can fail even when new right ?

stop making it sound like OMG ITS END OF THE WORLD NOW PANIC!

Yep, I was just letting some of the people in this thread know failures do occur with the new version.

With parts like ignition coils, they wear-out so slowly you won't notice decreasing performance until they get bad enough to cause misfires that trigger the engine computer's "limp mode" programming. Just like oxygen sensors, which also wear-out slowly and steadily until they exceed the ability of the engine computer to compensate for their age. You'll still notice an improvement if you replace the coil with a new one.

well i got the bhr ignition and installed it and wires ONLY (was getting late and ill do plugs later) throttle response is definatly better, and lower end has a wee bit more pull.

if anything maybe a few ft lb's tourque but nothing to write home about, but the throttle response and start up's are much improved (not that mine where bad to start with)

got a 2010 r3 install bhr with 15,000 miles with stock plugs, gonna swap with new plugs when my mid pipe gets in.


but one issue i did notice (which may be a non issue) idle is a little rougher it seems, sorta shakes the car a little not much and the back pressure or whatever it is from exhaust is louder,

that does not bother me at all. but i have gott 2 CEL's for random misfires.

BUT i have only gotten them both while the car was sitting idling for about 5 minutes plus. i have not gotten a single CEL while driving, but i have a feeling new plugs and a seafoam maybe will clear up all my issues

stay away fromn the seafoam please, lol, double check your installation if your getting misfires, even at Idle, its not normal at all, check the wires, make sure there all cliped in, and retorque the coils, if they are not grounded right they wont fire right, you SHOULD get a smoother idle if anything with this mod at your mileage

well wanted to update all.

did a small maybe 3-4 oz seafoam for maybe 45 mins didnt fix issue, made not noticable difference.

changed plugs, OMFG NEW CAR

it was better with the old plugs,

now it is even better then new =) not issues whatsoever now =)

now i need to get my midpipe in, guess it was made and being shipped bhr has top notch products and service very happy
