I have installed a heat shield but it is very temp. fix. I wonder if the stock air box and the Green Cotton air filter produce the same hp results. Engine does run warmer now and I attribute that to the air filter (heat soak) and the Supersprint header. I am considering wrapping the header with Thermo Tech header wrap to alleviate the engine bay heat. If the Green Cotton filter does not up the performance then I will reinstall the stock air box. I think the High flow air filter does make a difference but it must be shielded for cooler air.

I am going to dyno the car soon and will post results. Yes, I think that the filter did help the engine. I am also running an ASP Racing pulley and Supersprint header/muffler and more air coming in will be a good thing.
