Spark plug Bosch or OEM Subaru

I just picked up 6 Bosch dual electrode double iridium spark plugs from autozone near me and threw them in. Fires great!

I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.

I got a sp series cold air intake and ecs performance ignition coils with bosch spark plugs. I once ran this car with 3 spark plugs for to much time and almost no oil at one point too.

I couldn’t use any other spark plugs I had to use those or my car would run like crap.

In my 2012 with the 2.5L engine, I replaced my spark plugs with Bosch Iridium (#96302), around 90K miles. It's been great since.

I also added bosch sparkplugs 4 months ago, and also have some stuttering.

I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use

RIP doing spark plugs at home and not hating life.

Good luck doing spark plugs

I’ve had almost all of them destroy themselves recently.

A few months ago i had a intermittent misfire appear and went to investigate it but when I popped the hood while it was running, the wire on cyl 3 was literally popping and sucking itself in and out with the spark plug core still on. I took the plug out and the ceramic was moving in and out from the threaded bit. So it was gapping and slamming itself together while running.

I changed the one spark plug cause I had a spare ngk, I forgot about changing the rest and now I have a new misfire….. I can now feel the tick from combustion going thru the wires on cyl 1 and 4. So now 2 spark plugs are starting to do the same thing. I will be changing to ngk plugs now and won’t be touching Bosch.
