Agency Power intake for 986? Anyone?

[sd_boxster]

Has anyone fitted the Agency Power cold-air intake on their Boxster? I see lots of mention of the evoms intake, but a search for the Agency Power intake came up empty.

Just curious if anyone has tried this intake and if so, how it fared for them...

Thanks in advance!

Hello SD, newbies unite....You got me curious, I found this

Perhaps some other members can comment on whether they think you would feel these numeric improvements...what's the $$ for this modest gain??

FYI this test wasn't on a Boxster but a wrx, I think that car is turbocharged which skews the results in terms of applying the same gains to a Pcar..

turbocharged cars are notorious for getting LARGE power gains from simple intake/ehxaust mods.

I have no idea what real gain you would get from this intake on a boxster - i'll let someone else comment on that - but I do know that you CANNOT make any conclusions about what WE would gain based on what a turbo WRX gained..

apples and oranges

I wouldn't see why you would get a different result (or lack thereof) with this intake as you would get from the Evo intake.

They all have the same principle:
* Pull out the old air box (which by the way already IS a cold air intake),
* replace it with a new housing,
* put a cone air filter in and
* replace the tubing between the air box and the throttle body with a bit more streamlined tubing.
I don't think that there is much difference in who makes these intakes

So read up on the Evo intake and form your opinion.
I did that and decided that the few HP that you *might* gain are not worth the pain in the butt removal of the OEM airbox and the danger of fouling up the MAF with the oil from the K&N filter ....

I appreciate the comments. While I agree that the concept behind the intakes is the same, the materials (Agency Power is powdercoated steel, evoms is plastic/abs) differ, and I was hoping for comments about fitment for one over the other.

Personally, the performance "gain" is moot - if there is a 2HP +/- fluctuation, it won't change performance significantly. However, I love the sound that a cone-filter intake adds to a N/A car - that's why I want to add the CAI.

Thanks for the comments so far!

If the only goal is "playing cards in the spokes" then try de snorkeling first. It's free and reversible if you do it carefully.

not sure if it helps but sometime ago I replaced the OEM air filter with a K&N (oiled) air filter, difference in sound: almost zero, but it set me back by $225 for a new MAF
Then I tried de-snorkeling and this has a much bigger effect
I am also a sound junkie, here's a list of my "sound mods" on a scale of 1 (least effect to 5 most effect)

GHL exhaust: 5 (I took it off after 1 year as I couldn't stand the drone anymore) and went with the next line item:
"gutted" exhaust: 4 (open the exhaust, take the baffling out, close it)
de-snorkeled: 3
Secondary cat bypass pipes: 3
K&N air filter: 1

oh, yes I forgot one:
driving with open pipes: 100 (on a scale from 1 to 5)
