Hmmm, Spend time diagnosing drivability complaints for a living on these cars and you will see why bosch platinum 4's suck in a honda real quick. There's a sucker born every minute and ppl that buy those plugs for 4 bucks a piece are just throwing money down the drain.

 

Like I said, having Platinum 2's in my car made it sound like it was missing on 2 cylinders between 1500-2000 rpm. As soon as I put in traditional style Densos, smooth as silk. I, for one, am done with Platinums, at least in this car.

on many of the hondas ive worked on the bosch plugs havent performed so well, theres a reason why hondas come stock with ngks.

ngk > denso > bosch > ac delco

 

stay away from bosch spark plugs and go to ngk...
