Smooth As Butter ! New Ignition Coils & Twin Power
I have an 04' and one of the known issues that we have been having is the degradation of the ignition coils. Well I just put in a new set (4) of ignition coils, and I also had an HKS Twin Power ignition amplifier installed as well. I can say that acceleration & overall driveability has been much better. Just seems like acceleration through the gears is much smoother than before. In examining my old set of ignition coils I noticed a discoloration of the plastic on the top of the coils.

so does this mean we'll be seeing you at the next meet then?
Are you back to NA for awhile?
Do you feel like the HKS item was worth the money...I believe I found it and its a bit over $500...thanks in advance
Are you using OE ignition coils?
good to hear this Fred~!
So is the coil problem isolated to the 04? I have an 05 and its seen a bit of heat recently and I noticed hesitation afterwards while hot...

I have an 05, replaced my coils today. All 4 were burnt out with 50k miles.
Couldn't the ignition amplifier lead to coils burning out faster? I would consider stronger coils with an amplifier.

you'll get engine misfire CEL.
if it's your leading coils, you'll find it hard to drive, it will be jerky. Almost impossible to get moving from a dead stop smoothly. But keep in mind your coil can slowly go bad, getting worse and worse, so it doesn't always happen at once.
If it's the trailing coils, you aren't going to notice till upper rpms.

I might jump on the Okadas if I could get them for $500 a set. Right now, without having them in-hand, even then it's a toss-up.

幹他媽!
just curious... for your turbo, did you also upgrade the fuel pump, fuel lines and all the other stuff- i've been reading about- that have to be upgraded along-side to support FI? if so, were they ever able to figure out exactly what part failed that blew the engine? am just curious because i'm trying to learn more about it in general. thanks.

THE HKS Twin Power comes with a plug & play wiring harness for the RX-8, one end plugs into the wiring harness coil connections, the other plugs into the coils, another end plugs into HKS unit. It doesn't get any easier.
Still waiting on that coil deal

I installed a new set of the revised coils on our Stock car and it is running very smoothly with just them. FOr those with idle problems the one thing to make sure is that all the clamp connections at the intake MAF & throttle body are tightly sealed, use a 10mm nut driver or socket on them rather than a screwdriver.
I bought the HKS unit for the STU car and intended to install it with the coils above along with modifying the harness for the direct battery ground wiring mod, but am holding off ordering another set of OE coils pending Okada's decision. I may get the HKS TP installed this weekend. The one thing I like about the HKS harness is it has the potential to allow relocating the coils to a new location, like right down by the sparkplugs

could anyone recommend some ignition coils that they have used besides the OEM ones?? I'm trying to get the HKS amp but I want to upgrade the coils at the same time...I believe thats the reason I've been recently getting CEL lights randomly

my question is, will those $700 plasma coil set burn out like the OE coils do? I bet it would take longer for them to burn up, but eventually they might. If that's the case, unless you have a crap ton of spare money laying around, $700 for a new set of coils every 25k miles or less doesn't work too well.
On the other hand, with the HKS ignition amplifer, you might get ignition levels similar to the plasma coils, but at a lower overall cost, not to mention you use OE coils so when it's time to replace them it's $100 bucks like it usually would be anyways.
We need someone to be the ginuea-pig for these plasma coils and test 'em out
