Spark plug Bosch or OEM Subaru

Bosch provides OE for VW spark plugs. Plug your vehicle into autozone and just buy the bosch ones. They come pregapped.

My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.

Oil change at 123k miles \ufffd\" OEM filter and Castrol Edge 5w40 OEM air filter at 116k miles OEM cabin filter at 116k miles OEM Bosch spark plugs at 116k miles

My plugs seem to still be running great, only have about 35,000 kms on them.

Bosch components made in the EU (this is the important part) are in many cases the items that VW installed on the car in the plant, or better. Take the spark plugs for example, Bosch just prints the VW name on it and VW installs it in the engine.

I have just replaced the oil and all 6 spark plugs with Bosch Double iridium.

i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.

Worst case of electrode wear I've seen was on a set of Bosch 3-electrode plugs in a VR6. Plugs were so far gone, that five of six had triangular shaped center electrodes. Really thought I was gonna gall the head threads they'd been in so long.

I found Bosch platinum plugs misfired intermittently on GM v8s with the optispark distributor despite being identical to the Delcos.

Lesson learned: DO NOT EVER EVER EVER USE BOSCH PLATINUM (STANDARD TIP) SPARK PLUGS IN YOUR VR6 ENGINE.... THEY JUST DON'T WORK!
