Spark plug Bosch or Motorcraft

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.

I have about 30k on my plugs (Motorcraft OE). I've no problem buying them again as they've held up great

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.

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

switched to the back to the motorcraft spark plugs $15 a piece fixed it for a while

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.

I tried Bosch plugs on a 1995 NG900. Problem as described. When they state compatible, that might only address mechanical fit. Stick with the original plugs
