bosch spark plugs

hi guys,ive got some bosch super 4 fr78 spark plugs to put in my car which is a passat 1.8 turbo,awt engine 2002 model,has anyone had these in and are they any good

hi mate yes ive fitted them in a few cars over the years and they seem to be good

thanks for reply mate

Personally I would use nothing except an NGK PFR6Q in that engine but the Bosch equivalent is a FR 7 KPP 33+.

thanks for replying,why would you not use these plugs

VW only list their number 101 000 063 AA and this is specifically listed as an NGK application which I get as PFR6Q and NGK’s own listing says the same. VAG often list Beru, Champion, Bosch and NGK applications for the same engine, if given the choice I fit Beru as they have always been very reliable for me, Bosch certainly have not… The Bosch equivalent to 101 000 063 AA is listed as being FR 7 KPP 33+ and this is confirmed by Bosch Germanys own list and is a Bosch 0 242 236 564, the Bosch part number for an FR78 is 0 242 232 801 but that is their KSN number 509 which is what they say in one of their listings for an AWT engine and their equivalent to the VW number 101 000 063 AA lists two additional numbers to the FR 7 KPP 33+ and the Bosch FR78 is their number 0 242 232 501. I have sat here for the last hour and tried to make sense of it all and to be honest all I can say is Bosch’s applications charts make my head hurt…

thanks crasher for your advice,i have exchanged bosch plugs for the ngk ones

Have you fitted them yet, if so, any noticable improvement?
I have the Bosch ones fitted by the previous owner, but plan to fit NGK soon.

hi,havent noticed any improvement with plugs,car seems the same,and the old plugs had been in atleast 4 years and were ngks,one thing i surpose is they didnt let me down in that time
