I hate to rehash the age old question on intakes. As I was told, there is a lot of information out there...too much. Now I'm totally confused. I started off thinking zoo dad, then thought after market cold air since I read the stock intake is too turbulent. Then thought of the Tymar with the NAPA filter because it is cheap, but then I read that the air under the hood is too hot (hot air in = hotter air out). Then I read that the gains from intakes are minimal and not really worth messing with. Anyone out there have any real work advice? Thanks

 

The zoodad mod is just punch a hole or holes in the plastic behind the grill to allow air to flow to the intake. If you live in a state that see snow, I would throw a screen or something like that in there cause I have heard stories of zoodads plugging with snow. That is why I won't do it since my truck will rarely be shut off during a snowstorm.

A tymar is a style of intake aka the 6637 intake and IMHO is the best bang for your buck with a 7.3. The filter flows enough to support well into the 400rwhp range and is 99% efficient when up again coarse dust. Really it is an awesome filter, I have no plans to put any power adders to my truck and I run it for the superior flow and filtration.

 

I don't think the heat is even close to being a factor....unless you drive on the sun, the air coming out would be quite a bit hotter, I have a 6637 wide open under the hood and it works just fine

 

Yeah man! The only company you hear making a lot of noise about the dangers of "open intakes" is Banks. They make a huge deal about Air Density and all that crap but the 6637 intake is dyno and track proven to work just fine.

 

I guess on a non turbo/supercharged engine...it would matter, but compressing air creates substantial heat..way more then under hood temps, if this was not the case...the intercooler would be obsolete. Someone correct me if that's wrong. I'm definately open to any and all ideas

 

I agree 100%. Cold air intakes never made sense to me on turbos. As soon as the air compresses it's temperature increases substantially, not to mention the air already passing through a super hot turbo. The few degrees a sealed air box drops the incoming air charge has to get lost as soon as it passes the turbo, maybe even as soon as it hits the turbo. Like you said, imagine the air temp at the plenums w/o an intercooler.
