Spark plug Bosch or OEM Honda

My 2017 VW Jetta 1.4 5M - at 67760 miles on the factory original plugs - now has new Bosch Iridium/Plattinum plugs - (YA5KIP80)..................(the only symptom on the old plugs was a MPG drop - no hard starting, no missing, no rough idle......... EZ

changed out the spark plugs, all except for cyl 1 had crazy looking plugs. Used Bosch platinum 6704 cleared up the CEL and also the stability and TC lights no longer flash so somehow that was connected I guess.

For iridium spark plug. Do NOT gap them. I have bosch double iridium spark plugs and over 120K miles now. Still goes strong.

My car has Bosch Double Iridium spark plugs. Over 120K miles now still go strong.

I just got Bosch ones for my 2gr in the Lexus. Worked well, no complaints. And they weren’t badly priced

I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use

The car works almost fine with the new bosch , i have a little vibration on idling .

Never use bosch plugs. I work in a bosch car service and we won't use em, NGK only. Bosch stuff is garbage

BOSCH stopped German manufacture of spark plugs long ago, they suck now.

Mann fuel and air filter, Bosch distributor cap and rotor, NGK spark plugs and NGK wires. I had Bosch spark plugs W6DPO, the car runs exactly the same.
