I have installed an aftermarket (flea market $5) cone air cleaner on my 3.3 Caravan (2003) and have some interesting results (not scientific) Since there was no place to put the air temp sensor I just tied it to the wiring harness at the firewall. I took a trip and my SG which usually gives me low to mid 20's at highway speeds was giving me mid to high 20's with occasional low 30's. I think the combination of the cone air cleaner, the warmer air intake and the probably even warmer temp reading that the computer was getting combined to give me these numbers. Any comments?
