I've had my Bosch platinum spark plugs in for 120k+ kilometers and they still run as good as they did the day I installed them, back in 2011.

I like the Bosch icons they're a little spendy but last long and work well.
Bosch Icon for the win
I\u2019ve always had great luck with Bosch wiper blades. Agreed that the Michelin from Costco are garbage.
I ended up going with Bosch and haven’t had any issues.
Previous vehicles I've used Bosch Icon which have been great.
Just stuck a load of Bosch in mine, worked a treat, xHP throttle blip downshifts were sometimes jerky and causing transmission faults but now they’re as smooth as butt’uh.
13V is normal for a stock Bosch alternator. There are 14V or adjustable voltage regulator available as a replacement.
I recently had to repair my Bosch starter after hearing a weird noise while driving. It ended up that the starter drive would not return back so the drive gear was rubbing against the ring gear.
So, OK, ended up getting a Bosch Reman from IMC, installed it to find out it was only producing 10Volts @ idle. Took it back out, and installed an Ultima which put out 14Volts @ idle.
