another one on intakes

[cowboyupamrka]

well i got the money for an intake now and i am considering either the S&B or AFE. What would be the better way to go? I know there is quite a price difference but i am not worried about that. plus someone is having a sale on the AFE. I have always been a fan of the AFE, just no the price, but have heard pretty good things on the S&B too. Thanks for the input

S&B is the best bang for your bucks full intake kit.... if you want come over and check out the one i have installed on my work truck.... but that is a 3 hours drive from you

Between the 2 choices, S&B is the best choice. You'll get similar filtering, more CFM, and a lot better price. There's no advantage for the AFE ProGuard7.

But even better is the 6637 DIY intake and filter (~$40). Better filtering, and enough CFM for a stock truck. You may also want to consider the Ford AIS. Superior filtering, and the CFM's are unconfirmed at 775 CFM. If the CFM's of AIS are better than the DIY/6637, I'm switching. But the DIY/6637 is awesome.

I imagine you could also buy the AFE or S&B filter instead of the 6637 and go the DIY route. But the Donaldson/Napa 6637 filter is a better stock truck filter. If you have a modified truck (500+ HP) and need the CFM's, then go with S&B. Or if you want to sacrifice filtering for more CFM, there's some other options.

The open element filters will flow more air but NOTHING will filter better than the AIS. Oil Analysis prove this, my silicon levels are usually 5 and have been as low as 2. The open type filters are also very loud, I am getting older and now I want to hear my tunes over the engine, but maybe you aren't there yet!! lol!!! I can tel you this the AIS with zoodad mod flows all the air my truck needs. I have never had to back out of the go pedal due to high EGT's. EGT's are controlled by proper air flow and awesome tunning!!

With my 6637 my silicone reading after a 6,000 mile interval was also 5 REALLY the best "Bang for your BUCK" is the DIY,, filters wonderfully and MUCH more reasonable in price,,, more to spend on OTHER STUFF for the truck!

Im all about the DIY intakes also. read so many threads on intakes and not alot of evidence. one thing was agreed on though more filter area is better so on a DIY intake just get a large filter.

I've had similar results on my oil analysis reports running the 6637 DIY and the AIS, both work excellent for the 7.3L. In addition, both have supplied enough air for my setup at the 350 hp level. I did need to install the fender sleeve on the AIS to provide more air, worked well and cut down on the smoke.....

I have not seen any UOA reports from folks using the S&B, so I won't comment on that one.

all I run is AIRAID.... I have seen the tests and the dynos and seen how they filter and flow compared to others.... S&B is similar, but the customer service and the warranty is worlds different with AIRAID making them the best choice

I ran a aFe stage 2 intake on my '00 PSD, and now I run a DIY intake, and I like it better.

Costs about 50 bucks to make. Well worth it.

For those getting a Silicon rating of five with the DIY filter I would be interested in what type of driving you do? It is probably mostly city driving on solid surfaces!! The reason I ask is the enviorment to drive in greatly determines the filter that is best for you. In the city there isn't a lot of dust a debri in the air, out in the country where you drive more on dirt, dust and gravel than pavement a good quality filter is very important. A friend of mine did the DIY Napa element and the Silicon level was 12 while mine has always been 5 or below. When we first went over to the sandbox the Humvess were dropping dead all over the place!!! They didn't cure the problem with a huge open air element, they cured it with a Donaldson filter, same as used in the AIS. Problem solved!! I am not saying everyone needs the AIS, but comparing silicon levels from a city truck to one that is driven in extreme enviorments isn't a fair comparison. My main criteria was filtration, I wanted the best filtration possible, the extra air flow was just a huge bonus.
