If PHP's dyno runs are believable, then they really do very little to inhibit. Bill removed the snorkle on a stock intake and on the dyno, it performed very close to the same level as an aftermarket CAI.
My comment was tongue in cheek but just to understand ..."Bill removed the snorkle on a stock intake" meaning the smaller diameter pc that goes into the fender hole as mention in the above posts or he removed all the intake in front of the air box?

Yea he just removed the peice entering the fenderwell.

But, I can say there were absolutely NO adverse effects and the engine ran well at high RPM, which it does when I'm pulling our trailer up the 7% or more grade out of Camp Verde for that 5-6 mile stretch there.
Regardless of any observed improvement, doing the mod was fun, and, if a CAI can improve performance, then this one should do it at a fraction of the cost of a commercial one. I always enjoy creating something myself more than buying something someone else has made.

Right, right... I already have custom tunes as well but for $10 it seems like you can't go wrong, especially when an aftermarket intake goes for anywhere from 150 to 300.
It's very long and you'll see my first version was different than the one I posted here. But, there are three other versions by other contributors that I think are way cool too. Read through the whole thread and you'll see some neat ideas.

Yeah...that's the thread I was referring to.
SinCityFX4 over there.....keep forgetting I have different handles on my newer sites.

How do you know this? Did you put your truck on a dyno and log your A/F's? I'd love to see some empirical data that backs up your statements. Nothing personal, it's just the engineer in me.
So... on my 04 with no custom tune, would this be good or bad? Good since it doesn't mess with the mass airflow sensor or bad since it lets in an inch of more volume of air possibly causing it to run lean?
I'm just asking because I was planning on getting the pipe tomorrow and possibly doing it tomorrow depending on time.

Fair enough! As one engineer to another, NO - I did not put the truck on a dyno and log any "lab" (not real world) results. Please understand, I am not putting down valid testing methods, but, for probably longer than you have been alive, the government has been telling us the performance of these vehicles using dyno tests, that don't really model real driving. The "model" is the thing, isn't it?
So, what do you go with? Some test that SAYS you should like the results because, by God, the testing facility is certified to be the last word on this process, or, do you go with your own, subjective tests, after reading all you can on the process you are trying? People I respect have reported good results with this mod. I did it and drove my truck under fairly demanding conditions and could not discern any adverse effects. Please notice I did not claim any huge positive effects either! I simply reported a "user" observation in the real world, and, I noted the increased potential intake area. What is the fault with that?
