He is right...there is no place to tunnel it anywhere over there
or shield it....even if you made a box off the TBI & used your small battery breather tube
(that vents off harmfull battery gases) as an air tube- its just too small.
Pop a hood on an Impala and look at how they did it on their 3.5.
It ticks me off they didnt do that for the G6.
but alas....I wish you luck! Lengthening the MAF wires has been done many times with no issues.
