Which spark plugs should i use for my car (Bosch Platinum +4)? Also, i want to change them myself...how do i get this engine cover/battle shield off of the engine?

 

Supercharged engines are particular about plugs. Use the recommended Bosch plugs, nothing fancier like people with n/a w202 buy hoping for better performance. They extra money will be thrown away and performance can actually suffer. I think the model number has changed slightly but the store should have the equivalency chart.

You use a metric allen wrench or socket head to take the cover off.

 

+1, stick to stock plugs

 

good, so bosch platinum +4?

 

NGK IRIDIUM

 

+4 are not the standard plugs.

 

what is the standard? and its bosch, so i figured it would work just as well. is +2?

 

Stock is Bosch F7KTCR, how do these compare to the platinum +4?
