Over the last 150 L fuel usage has gone down from 11.4 to 10.7l/100km, just over 6% improvement, that's a pretty good result I think & I suspect the actual will be even greater as I was doing quite a bit of eratic testing over the period.
The above figure does also include some other mods as well, which have been going on before & during the 150L period, front airdam, some undertray work, and some on front wheel arch covers, but I think at least 1/2 can go to the air intake.
