Also side note but on my new m3 I can confirm Bosch icon xt fit right out of the box no swapping adapters or cutting needed, needs to be the xt variant tho.
I replaced my fuel filter/regulator with a new one from Bosch, and the little rubber fuel injection hoses connected to it.
After I cycled ignition like 5 times to build fuel pressure it started to make this sound.
Struggled a bit after starting it but after 20 seconds settled and it now drives good.
Car feels solid no lack of power or nothing.
I dare to say it even drives better than before.
I just did mine at 60k I bought Bosch and they’ve been great.
I have a N55, e93 And went through the same back and forth between NGK and Bosch. My car is 100% stock. Ordered ZR5TPP33 Spark Plug - Bosch and the car runs just fine.
My F15 had the Bosch ZR5TPP33-S from the factory. I replaced with ZR5TPP33 when doing the valve cover about 20K miles ago, and no problems so far.
I’ve used both Bosch as well as Anco blades in other household vehicles and both have worked well. I’d say the Bosch blades lasted a bit longer and were more effective in snow.
I bought a new Bosch coil from TT because the original in my '88 Scirocco 16V didn't have the exact readings the Bentley said it should have. The new coil didn't have the correct readings either according to the Bentley and it didn't make my Scirocco run better.
Bought a new bosch alternator and installed it.
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.
I chose the cheaper Bosch ignition coil. When I got home, I realized the spring inside was significantly shorter than my old coil's spring. I made no risk of putting this in and brought it back. I learned that Bosch parts used to be made only in Germany and were excellent, but now many are made in the US or China and are poor quality. The one I got was definitely not the German quality.
