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
