I pulled the plugs this morning and replaced them with Bosch cooper plugs, the only match that was available in local Autozone. There are no more misfires (for now), which makes plugs the culprit.
Pros: no more misfires
Vehicle:
Volkswagen Jetta
Mileage: 133000 km
Currently Running Bosch - Fusions - for Spark those seem to have Smoothed the Motor - 1 step Cooler .
Pros: smoothed motor, 1 step cooler
The plug they sent me (Bosch #4417 FGR7DQP Platinum +4) runs absolutely fine on my engine, actually it feels better then before, but I just worried if it is indeed not the correct plug, will it do harm to my engine?
Pros: improved engine feel, smooth operation
Cons: worried about compatibility, potential engine harm
Vehicle:
Volkswagen Phaeton
Part number: 4417 FGR7DQP PLATINUM +4
The Bosch side fires are an AAN plug that has a removable top. I will probably use those, they worked great with my B5 S4.
Pros: worked great
