I don't know anything about Duralast parts, but in the absence of good info I'd go with OEM parts. Coil packs IME are a pay a little more now or a lot later type part.

I'm showing my ignorance here, are 2004s coil on plug? If not I'm sure you're going to replace the plug wires as well.

How many miles do you have? I've never known anyone to replace their coilpacks during a routine tune-up. They're one of those parts you only replace if you have a problem. Otherwise it's money going to waste. I'd just clean them off and add a tiny touch of di-electric grease where the contact on the plug is and let it go for another maintenance cycle.

they need to be replaced i have a misfire in two of the 4 cylinders and identified the problem as coil pack i am going to replace all 4 instead of just 2 so that i can stay even on wear and tear with what i have replaced. I just dont know if my spark plugs and ignition coil is the only thing that i need to swap out

Oh, in that case that's all you need. Lucky for us, coil on plug = no wires. If you've identified the coils as bad, it's as simple as removing the bolt and putting the new ones in place.

For the love of Jebus, DO NOT buy ghetto coilpacks, get OEM ones.

NO! The coilpacks at autoparts stores are NOT OEM. They can say, "meet's or exceeds OEM specs", but that doesn't mean crap. Aftermarket parts makers can pick any "spec" they want to use and say it meets it. Trust me, I work for a parts maker that supplies aftermarket and OEM.

The only way to ensure you are getting parts that are really up to par for an OEM is to buy them from the dealer. There is a saying, "The lazy man ends up working the hardest". Well, the cheap man ends up paying more in this case. Spend a little more and buy from the dealer, otherwise, you will probably be replacing this part again, and paying for it again.

Yuppers. Also there is no reason to replace the ones that are working. There is no wear and tear on them. They aren't a mechanical part.

Long story short.... largely for electronic components (coil packs, alternators, spark plugs, sensors, etc...) Use OEM or OEM manufacturer direct. Meaning go to subaru directly or order from the manufacturer of OEM (Nippin-denso or whoever). Hard to give an exact reason other than just seeing non-OEM parts failure rate. I have seen a coil pack melt down (non-OEM), 02 sensors that do not change MIL until OEM is used, and so on.

This does not mean that some A.M. manufacturers do no provide quality parts, cause they do... But after time you learn who to trust and who to not trust. If your ever in doubt, use the advice above. OEM will supply with updated parts that are improved and designed to last longer than the parts that came with the car. A.M. just does not move at the same speed cause they have so many more products to cover.

I hope this helps.

Please heed this advice.
