Done some looking at the Zodad mod and can only find it done on F series trucks. Anyone done a '04 E 350 ? :dunno: The air box opens behind the headlight and doesn't touch the rad cradle anywhere else . There are 2 vertical structral metal braces to the side that need to be avoided and some ducting required to get cold air into the box . What are the issues if the air box is opened as per the zodad BUT not ducted to front of rad and was sucking hot air from engine bay/rad . If this mod is done is there any need to get a new <BIGGER><AFTERMARKET>MAP sensor ? Sig has other mods so far .
