Spark plug Bosch or Champion
I am running LiquiMoly Molygen at the moment, use LiquiMoly Engine Flush and Direct Injection Cleaner when chaining oil, put in new Bosch plugs and coil packs about 9 months ago.
Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.
I used Bosch iridium spark plugs in my 2018, no issues
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.
the original spark plugs died (delphi) so i changed them for Bosch ones
I have never seen any real large difference in NGK, Denso, and Champion if the proper heat range/type plug was used.
I'm not a fan of the old platinum Bosch design or regular autolite.
i bought ngk plugs and bosch platinum triple diode plugs and i got the coil pack off ebay.
I would return them and get Motorcraft anyway. Champion is garbage.
Never use the Bosch ones for the E46s. Just not working right
Don't use Bosch on 90s Toyotas.
