If you have a dead coilpack, replace that one coilpack as there is no need to replace all four. Get your ass on eBay and get a used one for $20. I have 310,000 miles on my car. I've swapped turbos 5 times. I've replaced ONE coilpack. They are light a light switch, they work or don't. Don't overthink this as there are plenty of topics in Subarus to overthink and this ain't one!

I currently use Cosmo Racing coils in my 05 Wrx. Mainly because they were cheaper than oem. Engine feels happier, but thats compared to 150k+ mile oem coils. Im sure brand new oem coils would have been just as good, or better.
Rallysportdirect should have a few options to choose from if you dont want oem.

Had Cosmo coils. Lasted around 40k, these replaced a set oem coils that had about 150k on them. The OEMs threw no codes or showed any signs of failure.

Purely done as a "this is cheap and maybe I'll give these a shot and see if they're better". Nope, not the case. One day, car was misfiring badly trying to go up a gentle hill. Replaced with the old OEM coils: issue solved. I then found a deal on a set of new OEM coils.

When the Cosmo coils let go, a new set of OEM coils went in. No issues. Old ones are now a known good backup, Cosmo coils binned.

Go OEM.

Performance Distributors now has the STi-spec coils for $200 a set. The difference between WRX and STi is the length of the rubber boot, just swap boots.

I've been running the Cosmo's for almost 120K and one just died. I couldn't remember their name so I couldn't find their site to order them again.

At the time I went with the Cosmo's I too found no OE's for under $85-100 ea. And the Como's were on ebay for I think $125/set.

They did fine. Also even though I live a fairly large Metro area (Dallas, TX) the Subaru dealers leave way too much to be desired. Worthless honestly.

Also, MSD and Accel offer EJ coil packs now as well. The Rally Sport direct options are $370 and UP (WAY UP).

Performance Distributors I called them this morning and they are on the way 5 minute phone call.

That's the external difference. The internal difference is the dwell time.


People have been cross-pollinating the 2.5 and 2.0 coils for years and results are purely anecdotal. As far as I've found, only OEM accounts for the difference in dwell. YRMV.



I figured, if the OEM lasted this long, a new set should outlast the car.

Because they still work, does not necessarily mean they are working good. Coil packs' performance has long been known to slowly diminish over time until it gets to the point where it begins to miss. Anytime I've replaced hi-mileage original coil packs, the difference is felt immediately, especially in cold weather.

Clark Turner recently posted this as well concerning hi-mileage original coil packs:
Quote:
If the coils are original they are weak. Just replace. I made a test jig to test them and after finding everyone was weak I no longer bother.
Again, not saying you can't get by, by just replacing one with a used $20 ebay coil pack, but in my view, you already have four used coil packs, why buy another?

I do agree with not over-thinking it though. Buy four new OEM coil packs, cry about the price for an hour, and never think about a coil pack again for the next 150,000 miles.

I've had the delphi coil pack from rock auto for 20k and it works great. Only $40.

I had great success with OTL coil packs as an upgrade vs just a oem replacement.

If you want to replace your coil packs, PM me.
I have the four (4) OEM coil packs off my 2002 WRX for sale.
Bought new in 2016.
Maybe 25K on them.

No longer have car. I can make you a MUCH better price.
