I am very curious to see their NA8 solution. I know the NA6 reroute was intended to be for both, but the fitting for the hose that leads to the oil cooler on the back of the NA8 head was an unforeseen inteference. I.L.'s reroute looks the most OEM (besides the IL logo in the casting), so it is the most pleasing to the eye to me (even if it's going to go mostly unseen). So the response they gave you has me wanting to wait for them to release their NA8 solution.
Otherwise, I plan to go with 949's new QMax reroute.
