Hi to all,

I just got my 1993 Spider Veloce (20 000 kms) and it seems that the spark plugs mounted on the engine are not the correct ones ?

NGK or Lodge(+2) or Bosch(+4) ?

Otherwise, I will have to change the engine mounts pretty soon, is it preferable to go for the original ones or for the heavy duty ones (more expensive) ?

Thanks for your help.

Thanks

Thanks Darren for your quick answer,

So I will try the NGK BP7ES spark plugs and will let you know how they
work with my 2.0 L engine.

My last Alfa Romeo (almost 12 years ago) was a 33 Quadrifoglio Oro, and I
really enjoy to be back to Alfa with my 93 Spider Veloce. Such a lovely car (I love the sound too) !!!

those NGKs are for older alfas. you need resistor type for your bosch motronic engine. i run my motronic on bosch fusion #4510. theyre the most expensive sold. are reccomended by bosch, who designed your ignition system. they have the four contacts that alfa preferred ( they asked for Lodge plugs because it was the only four prong plug in those days). theyre tested by me for yeqrs and confirmed to work in a daily driver. and lastly theyre sold by amazon for half the price of autozone.

I know listening to the stereo is secondary at best, but why not use the BPR7ES? It will diminish radio noise without any performance loss. :confused:

i do run my SPICA 1750 engine on NGKs but look for the ones wighout the E and therefore having the shorter J-conductor tip. good plugs for wothstanding fowling due to the varying richness of yourmixture by the injector pumps actuator. your motronic doesnt deal with that.

Is it necessary to set the gap on those Bosch Fusion #4510 plugs? (Its been a looong time since I changed plugs :eek: ).
