Put the correct spark plugs in there (NGK BKUR6ET-10 for AEG), throw those Bosch +4 turds in the bin where they belong.
Bosch F3cs @27psi no issues and no gapping
Bought Bosch platinum's and red bremi wires. swap everything all out, the misfires alot worse.
i bought ngk plugs and bosch platinum triple diode plugs and i got the coil pack off ebay.
Personally I've never had any luck with ngk's in any of my vr's always just run Bosch plugs and wires....
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.
Currently Running Bosch - Fusions - for Spark those seem to have Smoothed the 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?
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.
