Spark plug Bosch or OEM Subaru

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

got my f6dtc's at the dealer (only place i could find them), and they were around 4 bucks a piece. car ran like a dream.

i;ve ran bosch plat 2 prongs for 2 yrs no problems! once I got my arcing wires sorted...

For the stock heads, I recommend the good ol W8AC (Bosch Copper)

i put a heatrange colder (bosch FR6 because i can't get the ngk's local) in my bro's chipped 337 and it ran a lot smoother

I have used the Bosch Platinum +4's and I like them..... A bit pricey though.

I got W7DC spark plugs from the local foreign parts place...performance hasn't been ideal, and I've already looked at some of the other common issues; I'm considering new plugs in part due to fouling (bad CTS, drove with a failed CTS for too long, lots of carbon on the plugs...cleaned them up some, but I'm not convinced they're OK).

Platinum +4s are the worst plugs you can use. They have a bad habit of losing tips into the cylinders. I don't think I need to explain the results of that.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.

I have a strong opinion in not suggesting the Bosch or the Beru. There is a reason that BOSH is no longer the OE spark plug in VW, Audi, BMW, Mercedes Benz etc., etc... Stick to the NGK, especially in a VR6, NGK has been OE since the intro of the VR6 six months after Bosh failed to produce a plug that would run in these engine during start up. The Bosch had nothing but running problems.
