Unless K&N comes out with a FIPK soon, this is going in my new screw!

wow did you se they even have dino results of that intake. has a increase of 46 torque and 20 HP much earlier in the rpm curve. that might just be my next choice too. I can't believe K&N hasn't got one out yet. you know if you snoose you loose. I couldn't find any prices on that intake. dose any one know what they go for?

Just ordered mine.

EVG-400-140 New Airaid Intake, 2004 F150 with 5.4L Triton V8 engine., 25 hp 1 $298.81

$298.81
+$14.67 S/H
=$313.48

 

Those dyno results certainly are encouraging. The gains at 2500 RPMs are impressive. Power does drop a tiny bit above 4000, though. Not that I'll need more at high revs (I do alot of towing), but it would seem that by breathing better, you would gain power at the higher RPMs. Regardless of the dyno, I really look forward to hearing about it once you've installed.

 

I commented in the dyno thread about the results being interesting. I don't know that I believe it actually provides 46 more pound feet of torque over stock. I don't like that the "improved"airflow cannot make more power than stock over 4000rpm. I also think the numbers are low, like 200hp peak at the wheels is a 33% drivetrain loss. Was this engine not broken in yet?

I am sure the intake is good, but I would wait for further dyno results and/or competitive products forfore spending $300 on one of these.

 

I hated how the FIPK added so much "intake noise" on my 01.

No way I'm going to try one on my 04 until I ride in another truck with it. I LOVE the quiet cab.

Just my 2 Cents.

 

Your concern is valid. I have similar type intakes on my other vehicles. It doesn't make a noise until you punch it and the...BAM. Quite a growl.

As for the Ford, I put on a dual exhaust using Flowmaster 50 Delta which has a definite roar, but with the windows up, the interior noise is surprisingly still close to stock.

I found a local dyno shop and may take advantage of their dyno-jet and do a run prior and after the intake to see what a real person comes up with. Stay tuned.

 

Daneo2, definately keep us posted on your results. are you going to install it yourself? usually intakes are simple, but since the stock intake is a square filter and AirRaid looks to be using a different cone style, I wonder how it will fit? will it just connect to the stock filter box and just not install a stock square filter inside? let us know what you find. pics are always nice, too. thanks.

 

I was expecting this to arrive last Friday or this Monday, but now the retailer (Macromotive.com) tells me it is backordered and "should ship by the end of this week".

Anybody receive theirs yet?

 

Is it not an oxymoron to consider these systems as a cold air intake? The stock system is designed to draw air from outside the engine compartment resulting in the air temp being whatever the outside temp is. Sucking air from inside the engine compartment results in intake air that is some number of times higher than outside air.

To increase air flow, regardless of what a vendor claims, requires less restriction and that means less ability to trap dirt (oiled or not). Just like an oil filter, the trick for an air filter is to trap dirt particles measured in microns while at the same time allowing ample flow. Airaid, K&N, and the like flow air but do not trap dirt as small as the stock filter will. Naturally, the stock filter traps smaller particle sizes but does not flow as much air. Not trapping smaller dirt particles in race applications is fine but you have to think about what your engine is breathing in the long term in street or off road applications using aftermarket limited restriction air filtration systems.

Does anyone know what all the baffles are for in the stock air intake system? Ford, GM, and Chrysler all want to tout as much HP and torque as possible. If Airaid, K&N, and others actually increase HP and torque by double digit figures then why does Ford and the like all option for basically the same type of massive air intake plumbing? Do they know something we do not?

One last thing, a friend of mine installed an aftermarket type cold air system on his Powerstroke diesel. After a period of time he had a fuel delivery problem (not related to or caused by the aftermarket system) and two dealers refused to diagnose and work on his truck until either he reinstalled the factory system or paid them to do it.

Not talking down aftermarket systems like Airaid at all, just have a lot of questions regarding their actual validity when used in a daily driver.

I am not sure why ford or many other makes do not do many of the little things well known to people in the after market that produce extra power. there is many things out there like power chips, performance exaust, performance intakes and so on. perhaps ford and other makes are payed by the after market supliers not to build there trucks with those things. also I know the auto makers are trying to make these rigs as cheaply as thay can so there profits are up and many of these after market items are not as cheap to produce at least not as cheap as the items they use as stock. I wouldn't be suprized if ford and many of the other makes own stakes in many after market suppliers so they profit more if they design there rigs to work well with many of the aftermarket add ons. just my thoughts.

 

If they put all that stuff on at the factory it would take all the fun of doing it our selfs.

 

Ford distributed CAD drawings of the F150 to aftermarket tuning companies long before the truck was being sold. That's why there were more than 100 04 F150 aftermarket parts at SEMA this year. The aftermarket tuning market is hot right now, and Ford knows it's good for sales.

Still I don't think Ford dumbs down their trucks to help out the aftermarket companies. I think they probably want to offer a truck that appeals to the broadest customer base possible. If everybody wanted a super fast truck, we would all go out and buy Lightings which are everywhere for 33K right now. That's a lot less than most of us are paying for 04's

 

There is another factor here as well. The 2004 5.4 has 300HP with the current intake system. Next year, Ford can modify the intake to get an extra 10-15HP, and they get to market that as an increase.

It's all marketing. All the manufactures do it. If you completely tuned a vehicle to its max HP it wouldn't allow for later improvements.

Example: I got an additional 1mpg more on my 1998 w/4.6 engine with a K&N Air Filter(documented). I don't know how much HP gain that is, but it was noticable. I think Ford restricted the airflow on purpose, just to have the ability to increase it later.

 

that is a good point. I think they do that on alot more than just the engine. there is alot of things they could have done on this new model that they didn't do. obvious things like side air bags and full time 4 wheel drive. and there horse power looks to me to have room for improvement. things that will draw more buyers in the future and tempt those of us with the current model to trade in for the better thing.
