Help with Air Intake decision.

[red-rider]

Need help with decision on Air Intake, Any pro and cons with the AFE Pro Guard 7 Intake System for the 2004. 5, with the torque tube? Any recommendations?



I do not want to get a K&N, learned from past with other vehicles it lets too many fine particles in, even when properly oiled.



Everything is stock so far but want to start out with the intake first, then gauges, then probably remove the muffler.



Any advise is helpful. I live in California so noise will probably be an issue here, how loud is the truck with the muffler removed. Any sound files out there?

Straight pipes are loud. A straight through muffler is throaty but not rediculous, that what I'm running. Makes more noise and improoves flow but roll up the windows and you don't hear it.



The AFE megacannon is a great intake. Get the Pro-Guard 7 filter for best filtration and I added a prefilter as well, keeps the bugs and big stuff out to make cleaning easier. The torque tube does little for additional proformance without a highly modified truck but will really amplify turbo noise if you like that sort of thing. I bought all my stuff from Rip @ Source Automotive.

I pulled the muffler off mine last week and I don't care for it. I've run straight piped for years in all the diesel trucks I've owned, and I just don't like it anymore. Guess I'm just getting old. Find a good high-flow 4" system. As for the intake, I'm running the airbox kit from Diesel Dynamics and I like it. Came with an AFE filter.

Go with the AFE w/ prefilter. I too had K&N bef6re, never again. I love my Banks 4" monster exhaust. Sound is throaty but not loud. Torque Tube just adds alittle more turbo whine. I like being able to drownd out the rice burning kids at the lights

Thanks guys.

The aFe is definitely a better choice than K&N, but I wouldn't recommend the Proguard 7. I've seen quite a few posts of guys having their filter minders pull down more readily and that tells me it may be more restrictive than the stock element.



I've had good luck with Amsoil drop-in filters, they flow better than stock and filtering performance is good too. I don't think it flows as well as the standard aFe though.

You're right Vaughn, the filterminder does pull down faster with my Magnum Force/PG7 than it did with the sock paper filter but the egt drop tells a diffrent story. I wouldn't say it's more restrictive, just something about how they mount it in the tube. I'm also not willing to comprimise engine life for flow so I'll stay with my PG7. My $. 02... . tax free

SRadke I just came across this, which doesn't back up what I thought was true, in that the Proguard doesn't flow that well. This shows it flows well, I saw a post saying the aFe in this test was the Proguard 7:

Maybe what is causing the filter minder to pull down more is higher air velocity in the intake creating a venturi effect where the minder is reading from.

 

[SRadke]

Yea I'm not sure if it's venturi or just a lack of square inches in the tube but it'll pull mine down on a half throttle run.
