So how cold is cold enough for you MTI? And can you measure the difference from a stock air box to the temp you seek?

How about placing a small air conditioner in the trunk and running the cold air tubes to the engine, on the side of the car....to see if it runs any better. Or a block of dry ice under the hood in a canister....

It sounds like Chris17H seeks info to start a new business, and that's fine with me......but I'm not sure if this poll will do any good with Mercedes owners.

So tell me, what would you be satisfied with MTI...or Chris17H? Can you measure the temp difference? Why not cut a hole in the hood and make a small hood scoop just for cold air intake? There are many ways to do it, but what would be satisfactory....and who would decide?
