When I got my carbon fiber air duct, it did not come with a hole for the air inlet temp sensor. I used a drill the same size as the stock hole and drilled a hole near the MAF. No problem with the stock wiring not being able to reach.
As far as performance goes, I think it is better but I am not sure if it is because of the relocation of the sensor, the lighter weight of the air duct or both :jester
