AFE Stage I or II

I have a AFE Stage I, and was wondering if there is a big difference going to the Stage II? Is it worth it with the mods I have in my sig. Looking to install the ATS housing soon.

If you tow more than a rowboat, and have ever seen more than 1,200 EGT when towing up steep grades, then yes, you need the Stage II with the ProGuard7 filter. Or the Ford severe-duty AIS. The Stage 1 is certainly better than the stock intake as far as filtering the dust out of the intake air, but it's not a "performance" intake.

My Sierra Blanca (Spanish for White Mountain) in the sig pic was a great pickup for 11.5 years. I sold it several years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream. Replaced the 2012 with a 2019 F-150 3.5L EcoBoost with max tow.

Re: AFE Stage I or II

You will definately notice a difference with the stage II AFE. Everyone that I know that switched has loved it.

Re: AFE Stage I or II

I have the Stage I afe intake. I wish I had the Stage II. What I did was drill holes in the Stage I so it gets more air. However it is still a 4" hole and filter and I believe the Stage II is 5" which is better. MORE AIR.

Re: AFE Stage I or II

Just a little question....
Why would you want to spend all of that money just to have the "STAGE II" when you could have the Tymar or something like it and have "new" filters, as needed, for several years for the same cost?? Is it just the "bling" of the "STAGE II"??
Seems like a waste of money to me but then again, I for sure am no expert on intakes.
Just a thought....

Re: AFE Stage I or II

I went from a genuine Tymar intake to the best intake. Hands down better product. My baby responds better, and can breath easier. Oh and she laid down faster times too!

Re: AFE Stage I or II

donseye,

Any open element filter will reduce the performance of your intercooler, no way around that. They are better than a stock intake though! The Stage II have a much larger surface area in square inches of filter media and flows more, it has a steel heat dam to keep the hot underhood air out of the intake too. It basically just performs better as witnessed by many many members here!

Costs more but you know what they say you get what you pay for too!

At least three reasons:

Performance. The Tymar clone sucks its intake air from the hot engine compartment. Hotter intake air means reduced performance.

Noise. The Tymar clone is a noisy rascal. Most folks don't like the racket. The Stage II is much quieter.

Cleaner intake air. ProGuard7 filter lets in more clean air than the cheaper throw-away filters used in most Tymar applications.

Yes, the good stuff costs more. That's a rule. [img]/ubbthreads/images/graemlins/crazy.gif[/img]

How so Mark? >>Any open element filter will reduce the performance of your intercooler<<
And I can't buy the more square inches thingy. Side by side the Tymar is larger and it does have the "ripple" in the element to enlarge total surface area.
Insofar as the "steel dam", there was another guy on here who made a dam out of a used conveyor belt.
And was'nt there a post on this site about someone actually doing research on it. If I remember correctly, there was only about 1-3 degrees difference during travel. The big difference was at idle but that was only for intake ambient temp. I think the argument went someting like this; the turbo already compresses air and that automaticly raises temp so trying to "lower" ambient temp with cold air intakes is fruitless. Yes it can be done but the amount lowered is negligible as far as performance is concerned.
btw
I took off my "extra long" AFE that was planted in my Volant cold air box and put on a Tymar and there was an increase in performance as well as an increase in sound of our beloved whistle. :-)
Volant cold air box 4 sale!

but Mark, I for sure am no expert so if you know better, I will listen. (might not pay attention, but I will listen)

HEY! He has 23,000 more posts than you! YOU ARE NOT WORTHY!


But seriously, I made the switch; Afe wins. Tymar loses.

FACE FACTS.

Re: AFE Stage I or II

donseye,

Even at speed you will be pulling in hotter air with a filter laying open next to the engine, the AFE blocks it out and allows only the ducted outside air in! In the OLD days we built ram air systems with tiny filters that outperformed even with a small filter because it was outside only cold air. No proof other than using most all of them at onetime or another over the years, for soemone on a budget the open element is better than stock for sure but the Stage II pretty much blows it away. Folks like Hou-Tex have done it too and say the same thing!!

Take a used Baldwin or comparable open element filter and cut it apart and spread it out, then do an AFE. Now look at the air paths of the AFE and the paper, no way a paper can flow as much physically.

More power to a guy using a conveyor belt, I am not going to do that with my trucks engine compartment though.

When a turbo compresses air it does raise the air temp, therby the need for an intercooler, but why raise it more than necessary by sucking in hot air when cooler air is available?? The intercooler has a max amount of temp drop it can do, if you start hotter you'll end up hotter too. Hotter air is expanded, it will allow less air in the compustion chamber, less air equals less POP which equals less HP and less efficient burn too! Outside air is used to cool the intercooler, doesn't it make sense to use that same cooler air to help it cool even more?? Why do guys get new intercoolers, more efficient designs and create a denser air charge which makes a better combustion which makes for a more efficient engine!!

You'll always get more turbo sound with a paper filter as the AFE will muffle the sound as it is a 'soft" item vs a hard paper, that isn't necessarility a sign of increased performance.

I am NOT an expert either, but years of selling and see what folks come upo with makes me feel pretty confident of the Stage II systems.
