I have a 98 E320 wagon. I'm changing the spark plugs. The parts store said I should use Bosch F8DPP33 plugs however it looks like a number of post on this site recommend using F8DPP332. Has the F8DPP33 plug superceeded the F8DPP332 plugs?

 

seems they are the same except 332 is two-pronged.

"bosch platinum 2" is trade-name, as they have 2 ground electrodes.

i believe u can also buy the ones with 4 electrodes.
