				3.2L spark plug question
			 
			I have a twin plugged 3.2L with euro P&C's.  I cannot remember why I used Bosch W4CC copper spark plugs on this engine.  The factory plugs for a Carrera are WR7DC.  The electrode is more recessed on the W4CC plug.  Does a euro Carrera setup need the lower profile plugs? Jon | ||

			The US plug is a WR7DC and the Euro plug (higher compression) is a WR5DC. I don't know how twin plugging effects this. I think I'm running WR5DC's in my 10.5:1 twin plug motor. I would be curious to know how the "correct" plug for an application is determined.  -Chris | ||

			I cannot locate any W4CC plugs in Orlando.  What is the difference between the W4CC and W5CC (temp)? Jon | ||
