I have a 2001 7.3 stock and wanting to cut a zoodad mod do they work or should I go with a 6637 filter I think I have the wright number ?

 

Really they will pair with each other, so it's not a one or the other kind of thing. Not sure really how much the Zoodad actually effects it though. And yes the filter is commonly called the 6637, Tymar, Kwik, BHAF mod, etc.

I just drilled three holes to kinda of match up with my AIS intake snorkel.
Still like that now. Never had to open it up. Even if you go with a 6637
it is still good to get some cooler air past the header panel.

 

I did 2 2.5" holes like above, then used my 4.5" cut off wheel to open it up in between. Works great, using my air temp gauge, it really helps cool the air down after your truck sits. Like if you're at the store and its 85* out, when you start the truck its like 115* under the hood. Doing the zoodad cools it down a lot faster.

 

With this in mind do you guys think it would be beneficial to do this to the other side as well. Put cooler air in the entire engine compartment?

 

Keep in mind the fiberglass there also helps direct air over the innercooler, rad, and condenser. So you don't wanna take away from that. If you want to cool off the engine bay, maybe work some 2008 fender vents in?

 

Those panels are in place to force air through the various heat exchangers. Assuming your radiator, CAC, transmission cooler, and AC condenser are functioning properly, defeating those panels is probably going to do more damage than good in the grand scheme of cooling.

 

Thanks... Boy am I glad I didn't do that one. I would have to call it the OH ******dad....

 

I enlarged my intake air holes some years back. I highly recommend putting 1/4 wire mesh over this, if you have nesting birds where you live. Those suckers built a huge nest in the intake plenum that ended up underneath my AIS filter once I started the truck after it sat for awhile.
