I have a question...just saw the latest advertisement from BOSCH regarding their spark plugs. They show their latest and "meanest" platinum plugs. They have the platinum +4 and their newest Platinum 2. They do claim more..."vroooom" (sic)! I also know about other brands claiming such horse$h!t, like Splitfire, etc. I have tried those (on non-Volvos) and they did not do anything for me nor my cars other than lighten my wallet by a few extra $$$.

My question is: Has anyone tried the latest from BOSCH? And if yes, any difference?

I used 2 different types of plugs and it makes a difference.
The original Volvo titanium plugs make the engine run smooth with slower power build up.
The other types were quad electrode but I don't know the type.
The quad type made the engine more agressive but not smooth.
