   Will new spark plugs make any sort of difference to the performance or running of the car? I'v heard that bosch sell some cheap and cheerful ones. And how would i go about fitting them?
   Cheers

   They will help it run better and smotther.
   Possibly restoring a bit of lost power
   but they wont give you any extra power
   dont bother with super 4s etc, the only thing they do is last longer
   i prefer ngk plugr

   They wont add any bhp over standard. They may restore a few lost ones though, depends on the condition of the old ones.
   
   And NGK all the way
