Are you all using factory recommended plugs with your EFI ITB setups? Currently, I have Bosch WR7DC installed after my mechanic did a tune up a 1.5 years ago. Is this plug too warm for my 3.2 euro compression engine as the factory plug listed is a WR4CC (still available from Bosch)? They also list a WR4DP0 but that is an $18 platinum plug. What are the NKG equivalents? Any recommendations? Will the WR4CC be too cold with 92 octane gas (I try to get ethanol free whenever possible) when I have Al do his EFI ITB Option 2 kit on my car?

TIA,

Scott
