What do you guys think of these? And is there any chance they would do something on the 3.0s? This guy and that shop is local to me so I might ask them… (the mechanic installing the coils is AWESOME fwiw)
I’m interested in these as well, they at least look cool. Maybe Count can chime ? …
20tq and 10hp just from coilpacks? Interesting. Looks like they just glued a shiny badge on top of stock coils. Those coils are identical in every way appearance wise to stockers, besides the badge.
We need some brainpowwa in this thread
Yea. The guy who posted that (winston@podi) did lots of other testing with them, and ran them in his avant which he recently sold… It was a rare well-running 1.8T BAT lol.
I know they’ve been in a number large turbo builds in my area and they always seem to work really well. I know the 3.0 tune optimizes our coilpacks, so I figured maybe it could do even more with these ones.
I’m intersted in these as well. I was also thinking of doing the fsi coil conversion for my s4 when my icm’s crap the bed.
I wonder if they adjusted the spark plugs after installing those coils? It seems that getting a wider gap on the plugs would also be something to shoot for since you are getting that much more current on those puppies.
Does that say the price is $700.+ for 4?
Almost $1500. for 6 on the A8.

Plasma Direct based coilpacks are expensive!!!
Yea they are $$$. However the gains might be worth it. On a 1.8T its cheaper than an exhaust and gives you more performance gain.
$1500 for an advertised 10hp?
skip lol
LOL! 1500$ lets see, Recaro’s or coilpacks…
I think they would be more around 6 for $800 from the group buy. $$$, but who knows maybe with a tune they could yield a good chunk of power.
I frankly only think they’ll yield a ‘good chunk’ if your current coilpacks are shot.
Sounds like a scam to me. Hopefully I’m wrong.
Spark is an important component that is addressed in just about every other turbocharged platform but Audi/VW. I think the FSI coil conversions are a nice balance between extra spark and price though, and that these are indeed a waste of money considering people have made huge power without them
I think this has the potential to show gains for us, but not like people with turbo cars. The NA engine seems to have quite a large spark gap already, and I doubt you would make it much large by getting stronger coils. The people with the 1.8T/2.0T engines have been able to significantly increase the spark plug gap they’ve been running, which likely is a big reason they see the gains they do. It’s giving them more spark, allowing for better combustion. I think one would be better off, for the price that it would be for 6 new coils, to get a tune, intake spacers, and possibly downpipes. Or, get one or two of those, and spend the others on preventative maintenance.
If anyone lives close to a dealer and has access to a dyno, it would be interesting to see if the dealer would allow you to use a set of coils to test on the dyno comparing stock to Okada. Maybe state you’d be willing to purchase should there be significant gains seen, and then post the results here.
For perspective, a JHM supercharger, which adds about 150 wheel horsepower to a stock B6/7 S4, costs about $8500. It could add much more than that to a stock 3.0, depending on what the block can handle, considering it’s starting far lower than the 4.2 S4 started (i.e. delta from 275 to 425 whp = +150 on the S4 would be dwarfed by a move from 180 whp to say 400 whp = +220).
this is coil packs, which will die eventually and need to be replaced, and they’re 1/6th of that money.
Why anyone on earth would do this on a 3.0, to pick up an advertised 10 whp, I will never understand. I stress ‘advertised’ because as wel ALL know, gimmicks and stuff rarely deliver the advertised gain to all cars. If your car is horribly maintained and has a very inefficient system of mods, perhaps you’ll get your 10 whp. Is that anyone here? (and if you’re not modding your car or maintaining it well, are you really going to spend $1500 on coilpacks?!)
This is why I said someone should find a dealer that will let them test it on a dyno. They took a stock B7 2.0T to the dyno, checked it out stock first, changed nothing except the coils, and tested it again. It gained 10hp and 20lb-ft of torque. Is that worth the $800 one would pay for them for the 2.0T? Probably, considering anything after chipping the car is going to cost you as much or more. Until someone goes and tries them though, we’re all just guessing as to what, if any, gains there may be.
to make that valid they need to take the car, test it with new oem coilpacks and spark plugs, they replace them with new okada coilpacks and new whatever plugs okada suggests. Dyno and log before and after.
These guys are local. I’ll see if I can set something up with them. Won’t be for another couple weeks but it would be a good experiment.
exactly beem. That’s why I was mentioning that the advertised 10hp means pretty much nothing since we know nothing about the condition of the car they were tested on. Were its plugs/coils 60,000 miles old? Or 6000? coilpack recall done? If so, were they using the newest ones on the before test? Or the ones from 2007 that didn’t need to updated (my 07 S4 was exempt from the recall).

Re-read the thread and I saw this. How many people have actually had a failed coil on the 3.0? I’ve never had any fail, and I have seen maybe one thread at Audizine where a 3.0 owner had a coil pack fail. It isn’t an issue AFAIK on the platform, unlike the 1.8T.
- They will all die eventually. Do you think coilpacks are lifetime parts? Sounds like you’ve been reading the Audi maintenance manual (as it pertains to Audicare…a.k.a. Audi doesn’t want to replace them on their dime)
- They will also fade over time. Many cars with 100,000 miles on them will see problems making full power due to weak coils. That is why beemercer mentioned the 10 whp gains are irrelevant because they were measured against a car with many miles on his existing spark/coil parts.
But hey, be my guest. Run your coilpacks for life. Keep your spark plugs in for 55,000 miles each. Same with your fuel filter…55,000 miles. Oh, and don’t forget…don’t change your oil till 10,000 miles.
