have and 02 x PSD with 6637 filter but I figure even though its pulling lots of volumn the air is hot or warm at best. need a filter for my 00" f350 and before i do the same same 6637 install wanted some input. I've been told by local diesel shops that they have PSDs pushing 500 hp plus that are still running factory box with and non-factoy filter element and does not seem to be a restriction and cooler than my 6637. both trucks are factory other than a superchip programer and I have no major mods (engine related) planned for future.

 

I have the 6637. The "hot air" has been discussed at length -- to sum it up, the turbo compresses the air, so it creates heat right there. The intercooler cools it back down quite a bit to counter-act the compressing action. The other point is that when you're going down the road, the under-hood temps aren't that far off ambient. Yes, when you come to a stop, the temps go up under the hood, but my EGTs get pretty low at idle -- less than 300* after sitting for a minute or two. What it tells me is that even though the intake air is warmer when stopped, it's not being compressed so there's little heat being generated there. When under way, the intake air is much cooler, so it's less of an issue. The biggest impact will be when taking off from a dead stop. I haven't heard of nor do I have any problems with acceleration from a dead stop. One last thing -- the 6637 flows more air than stock, so another point to think about is how much the decreased restriction helps things.

I do have to ask though -- the statement about several trucks running 500HP through the stock airbox seems suspect. 500HP in our trucks is a huge number (actually, I think getting over 400 is a substantial achievement). Anyone taking the time to make those kinds of numbers is very unlikely to run the stock airbox with only an aftermarket filter (and I assume it is the K&N). Most agree that the K&N doesn't work well with our trucks, so I'd stay away from that one. I've personally seen dusted intakes & turbos with that filter, so I'll never put one in mine.

I have to second Izzy on the 6637 filter element. Its filters well, flows lots of air, and best of all it is cheap. Check out www.fleetfilter.com for the best prices. Also the inside of my intake was covered with dust running the K&N

 

I have the AFE stage 2 intake shown below..its one of the best out there..as you can see its an open filter as well..only different is mine has a heat shield around the filter to block out heat and push cold air through...if you are creative..you could build a shield just like it and get the same affect with your 6337 filter..I have no trouble with heat or higher EGT's..matter of fact they run lower then the stock box..

 

That is something I plan on trying out with my 6637 once I get back home. It's hard to do creative things when you're living at a hotel. I think I read something here where a guy used poster board paper to make a template to cut some sheet metal (I think it was the type for making HVAC ducts). It's been a while, but I thought about trying the same thing with a piece of foam on the top so the hood will close down on it. It will be interesting to see if there is any difference in EGTs, but I'm not sure the gauge is sensitive enough to see 20 or 30 degree differences.

if you look at mine it has a rubber seal over the top of the lip to fit tight into the hood..its just a piece of rubber window strip that slips over the edge...I will be doing a turbo swap here very soon..I can make you template if you like...then all you need to do is find a piece of rubber stripping..

 

I would go with the 6637. The minimal change in Intake air temp to me is worth the gain in airflow. If your worried alot about the air temp being pulled in by the 6637 Put 1-2" spacers between the hood hinge and the hood, it will raise the rear of the hood to vent more air out of the engine bay, plus i think it makes it look even more beast-like. But some argue that the hot air goes into your heater/ac intake duct and will make it work harder. so your choice. just some ideas.

 

Ron, I would be careful about making a templete for someone. You may get more requests than you can handle. Oh yeah can I be #2 on the list to get one. This heat shield would be a great addition for the 6637.

 

Let's not forget about the Zoodad mod that cuts a hole beside the raditor and the battery box to allow fresh air in as the truck is moving. Sorry I forgot the name of the part that you have to cut the hole in. If I remember correctly I cut a 3" hole.

 

For what it's worth....

I've run the stock box and filter, the stock box with the K&N drop in filter, the 6637 filter, and now I have the AFE Stage II. The stock intake box is a junky design, but didn't give me problems until I went with the K&N. That filter wouldn't hold a seal for anything, and I threw it away quickly.

I ran the 6637 filter for over 2 years. Never had problems with water, dust in the intake, or anything. It's a great cheap setup, but you do have to deal with some turbo and engine noise. My ball bearing turbo screamed extremely loud with that filter on.

Just a few months ago I had an offer to purchase the AFE Stage II setup for well under half the cost, so I jumped on it. The setup is nice, and so far the Proguard 7 filter has not let a single bit of dust into the intake. The other benefit is the noise reduction in the cab. It's still loud outside, but the engine noise and turbo whine is toned down a bit inside.

Now as for performance, I saw absolutely no difference between the AFE and the 6637. The only benefits of going to the AFE was a bit of noise reduction, and more bling under the hood. That's it. If you want the AFE, then go for it. I really like mine and think it's great. But if you are purchasing one to get peformance gains over the 6637 setup, then you are wasting money.

 

That would be awesome! I won't be back home for another couple weeks, so no rush... I sure appreciate it!! I'll PM you my address.

 

Ron that template would be an great idea
im running 6637 as we speak, and i like it my H2E loves it too,
can you send me a droving if you get to it ?

thanks

by the way did you get everything you need to do the swap???
let me know if you need anything before you start , maybe i can digg somthing out for you ,,,,

 

I'm ordering rest of the parts tomorrow..just got up the rest of the cash..I think ill get a new turbo though..id like a higher boost but until I up grade the HPOP and inj..ill just get a rebuilt from Ron's turbo..it has the stronger barons and the banks wheel..he said no surge..guess ill see..but yes ill make a template and send it out to ya..i think i stared some thing lol

 

LOL Ron, i think you did, and i think IZZY lead you to it very gently,

Ron till you get the other stuff in, run it stock, till you get it all , thats what i think would be best, till you get all the money for your toys, i know PMS is not easy to contain, but you might wanna try

 

I told Ron in the PM that maybe we should round-robin his template, that way he only makes one. I'll make mine, send it to the next guy, he makes his, etc...
