Sounds like alot of work for minimal results unless you're able to cool the air down quite a bit. I would think that all that piping would decrease throttle response a bit as well. What do i know tho...
Their are numerous threads about testing differences in intake air temperature between BMS dci and stock air box. Many say that the DCI suffers from heat soak. However, the tests proved otherwise stating that the intercooler balances it all out. It will be interesting to see your results.
