Will this work without messing up and running lean???
Can I install a CATBACK and this without the engine running LEAN or having any issues???
Would you guys that did this comment on how you like/dislike it?

It looks like it may have a couple of advantages.....one being the cost over a conventional CAI and it shouldn't be noisey like the others...........

I'd like to do this.

 

make no mistake, it's no subsitute for a proper CAI. you're "helping" the stock system, which is akin to giving an emphysema patient a little bit of oxygen.

 

I did this mod about 2 months ago. It's not going to save you several hundred dollars. It is on the other hand a good reason to get out of the house and "customize" the rig a little. Seriously I've seen no gain in any range and I've been running 93 on an Edge lvl3. I've had a constant 16-17mpg's no matter what.
05 XLT supercab 4x4 3.73 straightpipe.

 

The only way it would save me any money is that I could avoid buying an "expensive" CAI like the K&N or something similar.

Did this help "response" or anything at all??
And I would love to get 16-17mpg...all I'm seeing is 14mpg.....
but it can't hurt, right?
Thanks!

 

No harm done at all and if you don't like it it's not like you junked the parts. Returning to stock is easy. I already had the Edge so my "response" issue was fixed long before this mod.

 

If you search a little, there is a different take to this mod that makes it so you do not have to sand the PVC pipe down and is much quicker and easier fwiw. This mod will not run you lean and you can safely add a cat back without issue. The good thing about this is that you do not need custom tuning so it will save you money.

 

i did it. only noticeable gain was intake sound. gave the motor a deep roar. sounded good.

 

I didnt notice to much of a difference when I did this mod, but I just bought a Volant CAI so I guess Ill see the difference when I get my programmer also. Did you ever consider a tuner with custom tunes to account for the intake and catback? Then you wont have the stress of wondering if your messing with your engine everytime you drive.

 

A few years ago I did the earlier version of that mod, (when it was called the DWV intake) on my old 05. I had no tuner or programmer at the time, truck was bone stock at the time, I noticed a small improvement in throttle response, nothing for mileage. Later on I also cut off the sound baffles and the intake was throatier sounding. Not a bad mod, but if want any real gains, get a real CAI. You can also do this mod for zero dollars, just remove the cone shaped snorkel from the end and go with it, or spend the 10 bucks and get the pipe and coupler to extend it thru the fenderwell.

 

Ok don't want to sound dumb, but, what and where are the sound baffles?

 

OK....I'm just trying to justify $300 or $400 for a real CAI.......
the ONLY purpose of these things are that thye provide MORE air going into the motor.........
tell me why an expensive CAI is BETTER than this MOD........

 

Well, the stock intake flows "X" amount of air and the mass air meter measures that air flow. The PCM knows how much air is coming in based on what mass air is telling it, provided the data falls within the factory set parameters. When you change the CAI, you may be changing the cross sectional area at the meter, and if you do it throws the calibration all out of whack. To properly recalibrate the mass air, the mass air transfer function has to be rewritten along with the A/F table. Now most canned tunes, like the ones on the EDGE, only alter the A/F. Thats why they do not recommend using a CAI with them, only the stock intake.

So, any intake that does not require a custom tune, logically does not flow anymore than stock or very little more, becuase it does not change the airflow enough to take it out of the stock calibration window. Given that info, most all CAI's fall into that category, with the exception of the Air Force 1's in 3.25" and 3.5" sizes because they flow more air than the stock calibration can handle.

To answer your question, no an expensive CAI is not any better than the Gotts mod from a performance standpoint. Others may tell you that Y brand is good because of this reason or that reason, its all just basically B/S. The only real reason to spend 250 - 400 dollars on a CAI is for a real performance gain. Most all CAI will only give you about 5-10 hp gain, the gotts is worth 7 hp, so you decide. Just for reference, I've personally seen back to back dyno pulls vary by as much as 10 hp, same vehicle, same tune, same dyno, same everything, literally back to back. So if a dyno can have that mach variance, any gain less than 10 hp should be questioned, is it real or just the dyno.

Basically, most all CAI's are just bling, nothing more. They are just glorified soda straws.

BTW, the air force 1 intakes are no longer in production, the company went out of business. You can still get them new, until the supply is exhausted, or pick up a used one.

 

the sound baffles are the sections with the square dimples in them, circled in yellow.



BTW only the 5.4 engine has this intake.

 

Is there any benefit to cutting off the baffles other than having a somewhat cool sound? From what I've been reading the mod of enlarging the air intake tube you can get a quicker responce at WOT. I am thinking about doing both mods. Also I have an extended warranty that is still in effect, could cutting the baffles void this warranty?

No, cutting the baffles off does not void your warr. Yes you are correct, removing the baffles only changes the sound. Yes you can do both if you wish, I did on my old truck.

BTW you can alter or tune the sound after you cut off the baffles. Just plug some or all of the holes left in the side of the intake tube to tune the sound to your liking.
