I was searching for spark plugs and found these on www.autohausaz.com
Is there any difference between them and are these will fit c32?
Let me know which one you prefer and let me know if you know better place to get plugs.

1) 7407 Bosch OEM
Spark Plug; Copper; 3 Ground Electrode; OE Plug Pregapped for normal usage. $4.28

2) F8DC4 Bosch (Alternate Selection)
Spark Plug; Copper; Standard Electrode; OE Plug Pregapped for normal usage. $1.61

 

Get the NGK Iridium IX, and maybe one step colder. You running any engine modifications?

 

No, everything is original pieces. No engine mod.
So, we need 12 spark plugs, right?

 

They will both fit.

Yes you need 2 plugs per Cylinder.

Even thought you don't have any mods I will still go with the NGK Iridium IX works great with our cars

 

that's like saying you are going to go with the same manufacturer tires that come with the car to stay OEM? With replaceable parts like this, you are better off going with the better product.. (same with brake pads)

 

The OEM plug for the C32 is the NGK IFR6D10 (only the MB version with the blue star on it):

Yes, you need 12. I would advise against running a copper plug, unless you plan on frequently checking and/or changing them.
