Higher intake temps will reduce power and increase knock.
Both our engines are non ffv.
My car is a bit of a special case, it is a sohc 3.2 but the computer thinks its a dohc 2.7. I've always had light knock around 3200-4600 rpm. But now with a grill block I get knock all the time if I push it past 3k and 30% load. I'm hoping e20 will solve my problems. Will have a fill up soon.
