To be totally honest, I've been in the NA game some time and I've never heard of performance coilpacks. Even with spark plug wires, it's best to run new OEM or Rallitek ones if you like the colors.

Coilpack-wise, OEM or replacement would be your options. OEM being the better choice here.

If there are performance coilpacks, someone please chime in.

Had a 350z for about 6 years and I also have never heard of performance coil packs. People used to claim 1-2 hp out of new wires but I doubt that has ever been proven. Save the money unless you need to buy them anyways.

Lol, guess you haven't been in the game long enough.

You can use an MSD coil p/n 8239 but you will also need to buy an MSD pigtail harness p/n 8883 and create your own pigtail or just hard wire the new connecter into your car.

^That MSD coil will probably be listed as being for a dodge neon, but the p/n is good.

There are a few "performance" coil packs around. MSD is the easiest to get, not sure it's "worth it", but not an expensive try, especially if your old one is going.

As to "stock", the Diamonds are supposed to be the best. Keep in mind, different years had different output terminals (to the plug wires).
My 1998 Legacy 2.5GT had male pins on the coil output (never really liked those) but a 1998 Forester 2.5L had female outputs. The Forester coil pack is a Diamond.

oem, are you using a MSD??

I had an MSD on my 99 LGT. It felt much snappier, but you know how the butt-dyno can work

I have the MSD coilpack on my car. Can't say I could tell any difference, but it's pretty and red, so it must be better.

I'm using the stock (Subaru) harness to connect to the MSD. I had to pull two of the terminals out of the connector and swap them, but it's been long enough that I don't remember which two I swapped.

Same as Patrick, I ran an MSD pack on my '93 GF8 Chumpcar but really couldn't tell the difference. I tried to run a used Neon coil but it crapped out two hours into the race. I'm back to the stock coil due to rules and penalties associated with aftermarket coils. I ran the coil to hopefully improve gas milage during the race and possibly save one fuel stop in an 8 hour race. I didn't notice any improvements and we still ended up with the same number of pit stops.

A few threads for reference...

I'm a firm believer that in the Subaru world, the only time you see an improvement with a "performance" coilpack is when the OEM unit was going bad anyway.

my 0.02 anyway.....

A couple of random notes.

(1) The MSD coil doesn't line up with the coil mounting holes on the intake manifold - not surprising, since it's not designed for our cars. I originally had it bolted to just a single hole. One day I noticed that one of the "prongs" of the coil had a crack in the plastic. I think that the combination of my Grimmspeed phenolic spacers + the taller MSD coil meant that it was actually hitting the hood. Oops. So, I shifted it so it no longer sits on the coil mounting pads on the intake manifold, then zip-tied it in place with heavy duty ties. Seems fine now.

(2) It may be completely unrelated, but I get better highway mileage now than I ever have before. I can't definitively say it has anything to do with the MSD coil, mind you, since I don't always bother to work out the math, thus I don't know when exactly the better mileage started. Plus I've made at least one other significant change that could be responsible (going from my Injen CAI back to a stock intake setup). Maybe one of these days when I'm planning a long highway drive I can swap things out and compare. There are so many variables involved, though, that I don't know that I would get any meaningful data.

Probably true. For those of us with the old style coil packs, there may be some gains to be had by switching to the coil-on-plug setup that all the newer cars use. That setup seems to work fine for turbo motors making much more power than we are.

Sorta along the lines of the "grounding mod".....half of me wonders if they had crappy grounds before the mod, then doing the "grounding mod" got the electrics back to "stock condition".......Since I've never seen a back to back test, I don't know.

Interesting thread. Never knew these existed...
