AIS System

I just installed the AIS system from Ford on my 99 PSD. I haven,t had it on long enough to tell about any performance gains. I put it on mainly for a better seal. I would have gone with the Tymar but I still have an extended warranty. I am tempted however to drill some holes in the part of the grill right in front of the snorkel .There is an opportunity to get somemore air in there with very little work. As long as there was some kind of a screen prohibiting any large debris getting in the airbox does anybody see any reason not to do this? I do not know if this would have any impact on the warranty or not. Any help would be appreciated. Thanks, Brent.

Search the 7.3 archives for the Zoodad modification.

Get a comfy chair, because it will probably take you 2 days to read all the discussions.
