Hi,

I'm intrigued by the effect of the cold air mod on FE. I haven't done this mod myself but with Engine On Coasting I've noticed my engine takes much longer to get up to temps - my plan is to block the grill when I finally get time to do some work on the car. I note you have done that.

If the engine is cold though, won't that make the ECU pump in more fuel when you don't need it, so in the long run it may harm FE rather than improve it ?

Thoughts ?
