I am going to up grade my air filter.Looking at the scotty III or afe,or air raid.Any pro,s or cons.Thanks for any Info coobie

Having had both an AFE filter and now the new improved UNI foam filter in my Scotty II, I think the Scotty Air Systems are the ONLY way to go.

Good Info Lary,Thank you ! coobie

There all the same none of them bring in more cfm cotton gauze or foam filters stock air box 300cfm scotty afe bd power quadzilla intakes all 800 cfm nobody can prove different no dyno testing nothing go for the best price I find that to be with AFE and since all the other manufactures excluding Scotty's use their filters your getting the same product. We're in this business for the customers benefit

Hey Kyle..

What about EGT reductions.. Can you give us your opinion on these issues in relation to air intakes.

All the same once again that is what is beautiful about my job man I get to test everything leaves alot of parts just sitting on the shelve but it is fun. Although Scotty air is going to be realeasing a shaker hood set for the 3rd generation dodge's with a cowl induction facing the windshield to take air pressure off the windshield and direct it into a airbox with two uni filters feeding into the turbo as long as they can find a way to insulate the setup from heat I think this will be in the lead for lowering egt's but have your wallets ready this is gonna cost you for it will probably be the most expensive air system on the market. One more thing I have been researching is a cryogenic setup I saw at Sema for imports it uses a manifold that releases co/2 simple concept you just mount this infront or on your intercooler and when you hit the switch it releases co/2 which is naturally below freezing when it is released under pressure it cools down your intercooler which would cool down your intake air temperature to help lower egt's if you could find a way to have this go off via temp switch by Egt's that would be trick. I'm going to try this out in a racing application I will post a forum when I have results

Well for lack of better words I feel you are wrong in your statement that the Scotty lowers egt the same as the others.

I am referring to the Scotty Air II as I saw no mention of the RAm Air 3. It will reduce egt better then whats on the market...How do I know this?

Tested them all. Was always surprised at the results as I expected another product to be the better wheel.

When did you compare these and on what truck?

Theres been other folks stating the Scotty does not work, then put one on and compared it to their other aftermarket or their factory intake...the Scotty did better.

I should clarify something here. I do not suggest the Scotty II or the RAM air 3 for increased horsepower or mileage. Some individuals have found these results. A dyno test will not net any favorable results especially with how I designed the intakes to work with the truck on the road in the real world. Not in a static environment. I do claim egt reduction and I only suggest the use of a Scotty II if you have enhanced the power of your 2nd gen Ram by at least 50HP or you tow heavy.

The Ram Air 3 really shines with reduced strain on the turbo with its ram air design as well as its egt reduction. It does not reduce egt as well as the Scotty II on the 2nd gens. However, we are dealing with a different breed of Cummins design that had inherently higher initial egt from stock while under load.

Having less then 6 PPM silicon on all my tests since early 98' is nice too.

I have the Scotty RA3 and like that it draws from two locations. Some setups I've seen simply draw in hot engine air, and some have a heat shield and draw from the fenderwell. I think at highway speeds with the air being forced directly in, the engine is a bit more responsive. When I got mine, it came with an AFE gauze filter, now it comes with a foam UNI filter, which should do a better job with filtration. I guess when mine wears out I'll upgrade

I agree with Scotty on this one. We have tried several intakes on Jeff's 2004 and found the Scotty RA3 with 2-stage foam filter to the best at lowering EGTs. It also add a little seat of the pants as well and the 2-stage foam filter is better at stopping dirt than many of the performance filters available.

Four words!!! BHAF.....

Scotty

Uhhh thats four letters



Better Have A Filter

Dodgezilla

Uhhh Riiiiiiiiight...........

The AFE is a good product as usual.
Probably comes down to what pleases the eye.
The S3 Clear cover and foam element are very pleasing to the eye.

Scotty

Lately its been surprising how many folks want the clear units.

I have them. However, they do have a few flaws due to the assembly process.
When glued together, the glue clouds the plastic on the seam and its not a constant or uniform look.
Also, clear is very unforgiving when it comes to any imperfections on the molds.
Plus, now the cost of clear has gone up.
There would be a $50.00 surcharge on a clear intake kit because of that increase and getting the thermoformers to do a special one off run.

Scotty

EDIT:
I guess I better double check my numbers sometimes.
and tell my group of dealers and distributors what the deal is.
Its $25.00 extra for a clear in US funds, not $50.00 Canuck bucks.
The set up charged was waived.

I put a K&N FIPK on this weekend. less than $250 shipped from JEGS.com, after some haggling and price matching.

good solid unit, braced & bolted down tight.

it mounted the IAT outside the air flow, just on the heat shield panel, so it is not getting cooled by the air flowing over it, just setting baking in the heat, so I think the computer is thinking the outside air is hotter than it really is, which would retard timing on a gas engine, so prolly hurting performance.

i'm not real happy with my FIPK (esp the poor filtration) but I wanted to replace the whole tube from the turbo up to the air filter.

I'll prolly drill the K&N tube and put the IAT in the tube (i did this already on a PVC intake I made).

and use a BHAF if I get in a dirty environment. all I do now is interstate 95 and in town driving.

the K&N complete was cheaper than just the AFE filter, the best I could tell. The diesel websites aren't very informative in telling you if it's just the OEM filter box that is replaced, or if it's from the Turbo up. and I never found a price on a "torque tube" or a website that had detailed info.

the K&N is VERY loud. you can hear the turbo over the striat pipe 24/7

there is a website that sells all the stuff to make your own tube up from 4 inch, i just got impatient. it's like $25 for their stuff. you could do that a Scotty, and prolly be good as anything out there, if not better, judging by the Scotty testomonials on here (not from Scotty, but the guys)

i got marginal gains (2~3mpg) at low speeds, but still ~16-17 @ 80mph, due 4x4 ORP, I guess.

hth?
