Heat soak isn't an issue when you're moving and that's the only time when the newmission mod might be beneficial to the Typhoon--when in motion. I suppose that it may help the intake to recover more quickly from heat soak that has occurred at a stop. However, I doubt that it would be any more beneficial to the Typhoon than the snorkel delete (with cutout) is.
There's already plenty of cool air available to the Typhoon at speed. I see very little heating of the intake from the OBD2 data, except at a stop, and the temps recover quickly when back in motion. This is before any "ram-air" mods. I have not performed the newmission or the snorkel delete with my setup (yet).
