Spark plug Bosch or BERU

I've run Bosch iridium's in all my vehicles (boosted and daily). No gapping needed.

Bosch should be the safest choice for German cars, but avoid their gimmicky "Plus 4" plugs that have 4 ground electrodes, unless that's what the car came with from the factory.

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

Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.

I am getting better MPG,but It seems a little lacking in the power dept. compared to the autolite copper I had in?!Especially as far as low end torque.

But otherwise, Bosch FLR8LDCU+.

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!
