Description

The Plasma Direct Ignition Coils produce 4 times more spark energy than stock coils and also generate an ultra fast multi spark discharge of 10 sparks up to highest RPM. The spark amperage is increased 100%, allowing the spark to reach many more molecules and therefore accelerate the ignition and combustion process. This is extremely important in forced induction applications but also improves the performance of naturally aspirated engines.

The Plasma Direct Coil Pack will increase horsepower and torque throughout the entire rpm range. This upgrade will also reduce fuel consumption. Even the engines with a legendary smoothness will be further refined with the Plasma Direct upgrade. The Plasma Direct Coil Packs are OBD II compliant and C.A.R.B. approved.

Installation is easy. Direct bolt-in to the engine, no splicing or cutting into stock wiring, simply replace the stock coils with the Plasma Direct Coils and you’re ready to go.

This kit includes 4 coils

Great coil.
skierbum9736088 3 years ago
I couldn't tell you how much power I picked up by installing these as I also did a couple of other mods at the same time but they are a good coil. The plastic can get a tender after a couple years and I had to replace one because of the clip getting brittle and snapping off.

Testing; Dyno pulls; on Okada Coil Packs Audi 4cyl.

Here is a nice piece of work regarding these coil packs; although its on a Audi, the results speak for them selves. Very staight forward results on this Link: http://www.audizine.com/forum/showthread.php/380963-review-2-Okada-vs.-rev-D-vs.-rev-R-coilpacks-Bosch-FR6DTC-vs.-NGK-5238-spark-plugs It sounds like if you really want to maximize your results, a tune(as stated by RSD) is strongly recommended; and now you can see why. Hope this helps! Stefan, Milwaukee, WI.

  • Q: fitment  Exclsr 5 months ago

    Answer

    Any particular reason why it says these do no fit 2015+ Subaru Sti? says it fits up to 2014... thanks!


    • A: These will only fit up to 2010 STI's. We get all of our fitments from Okada directly and do not install every product we have on the site. If you have any questions regarding fitment and why they won't work on your 15+ you will need to contact them directly.

  • Q: Okada plasma direct coils  Deputee 2 years ago

    Answer

    Are these coils a direct stock replacement? And if so, is tuning required once installed? Thanks


    • A: These are not meant to be a stock replacement coil pack. A custom tune is highly recommended after installing these.

  • Q: plug fowling  matthew_schauer54975 3 years ago

    Answer

    Do you think that the increased voltage and amperage with these coils would help delay spark plug fowling?


    • A: This will not lead to increased fouling of the plugs.


      Stevens Henager 3 years ago
    • A: i don't think so either. my question was, do you think these coils would help prevent the plugs from fowling.

  • Q: EJ207  dennis_b9272195 3 years ago

    Answer

    will these fit JDM version 7 EJ207?


    • A: These coils would more than likely fit an EJ207 engine, however we cannot guarantee fitment for any model that is not in the Confirmed Applications list.

  • Q: Will this be good for my 03 wrx??  Peterwrx 4 years ago

    Answer

    I just put on a up pipe & down pipe catles and had it tuned and now 2 of my coils are not working . Will this make any chang on the performance of my car ??????


    • A: These coils provide a stronger spark than stock and are recommended for cars making more than approximately 400whp. These will be beneficial on lower powered cars, but you get the best results on higher powered cars. We recommended diagnosing the issue before replacing parts.
