Ignition coil upgrade: Okada Plasma Direct
 

Has anyone tried this product?

Yea got them on the car for a while now. First impression was the engine ran smoother, I think there might be a slight power increase but hardly noticeable.
I'll see what it can do with a retune, after getting my car fixed :crap:

got it via maperformance when i got my fp red, fuel system, cams.... installed 2 months ago;therefore do not know if the ignition is working or not.

got it for the peace of mind that i have the ignition system taken care of.

Did anyone trigger any code after installation? (ie: P1238).

From what i read, this device works well but you will need a retune. Depending on what boost/power you are already making, adding this device may exceed the torque limit capacity and throw out a code. Did you guys run into similar situation?

Nope no codes, but my car was already tuned when I put them in, didn't re-tune after though.

yeah, I had an code thrown I guess but I don't have a engine code reader but the engine service light had went off. In any case, I guess it took awhile for my ecu to calibrate according to the coil packs....but the service light went out. I had seen better gas milage and noticed a smoother power band when accelerating since I installed this.

Hmmm, I'd say that the factory EvoX COPs (coil on plug) should support quite a lot of power. I am familiar with Okada COPs. They are pretty popular on the Subaru cars that I tune too. No real data for you though. I'd say if you wanted to experiment with pushing the gap out a bit further or you wanted to make big power then the aftermarket COPs would be a good idea.

Did you guys install new set of spark plugs when putting this in? if so, which ones are you running with?

Not much available for plugs at this time. NGK makes an expensive *race* version of a plug that works on the EvoX but they are $$$.

I didn't buy any new plugs yet. Maybe later on I'll get some HKS plugs but right now I have the stock plugs.

What is the part number you mentioned for NGK?

There are also HKS plugs and Brisk Silver plugs for our cars.

It's around here somewhere. I'll see if I can dig it up....

fuel economy
 

anyone notice fuel economy, also will i need to upgrade to better plugs, or will i be safe on stock plugs

What kinda gap are you running with this ones ??? Also did saw any improvement while running the AC or heater on the car ???

thanks
