AFE momentum GT. In all honesty I can't tell any difference. I had a k&n filter and HC lower with headlight inlet before though.
I went out for a little drive straight after and the first open road someone was right on my bumper. They pulled out to overtake so I hit the gas. I had no idea what it was. He was passing me when I let off at 150kmh (speed limit is 80). It was a Focus RS!
Anyway. I did a few runs consistently getting around 6 to 6.1. It was -2c out. Roads were a little slick.
I think the tune is next on the list.
