I recently bought a 2000 GT. The car has a lot of mods - spoilers, clear corners, ect. The CEL came on so I took it into the Dealer. He said there was P0440 code stored and told me about the CAI(I did not know it was'nt stock). I have been trying to figure out what brand it is. It is not an Injen or AEM although it looks sort of like the PowerHouse only silver. I would like to know what I have. I have a photo but Ican't figure out how to post it with this message. Is the CEL code related to the CAI? Any suggestions?
