Ignition coil Bosch or OEM Volkswagen

All 4 coils (they´re now Bosch red color)

my first bmw was a 2007 328i and kept having misfire issues. Tried 6 new coils from autozone, still had misfire issues, returned them and ordered Bosch. Misfire was gone.

Whenever I need a coil, I try to find a Bosch blue first. For whatever reason they’re scarce, but I’ve always had good luck with them.

I also got my OEM coils for free but i do now need to replace mine, and will be going Bosch.

i ended up going with BOSCH 0986221072 ignition coils, no issues with stage 1 tune so far. Put almost 20,00km since installation.

Try 07K905715G BOSCH

I have changed the ignition coils, spark plugs, MAP sensor, fuel filter, and ran fuel cleaner in the tank twice. The only time it seemed better was for a couple of months after I changed ignition coils (Bosch).

I have them with APR Stage 1. R8 coil packs are not really an upgrade that people make them out to be... red = more performance.... Sure they came out of a R8 and V8 Touareg "BAR" engine code... but the coils make enough current to get a spark. The spark plug does the rest, and the features of the spark plug help with getting the air-fuel mixture ignited and burned. Because of the popularity of the red coils, you can often get them cheaper. I think last time I paid about $100 for the Bosch red coils from ShopDap.com

Honestly it just sounds like a bad coil on 1.

I never use aftermarket coils, nor would I. I have taken out too many bad ones. In fact, a friend put a set of some parts store coils in his daughter's Tiguan, and two weeks later one died.
