Default APS 65mm CAI vs K&N Typhoon CAI????

I'll be getting a ProTune in exactly 2 weeks, for my catless DW TBE, using Cobb AP v2.0 as EM.


I've done my research and I plan on adding a CAI on the day of the tune to squeeze out a few more hp/tq and help improve response... plus the ricer sounds are cool. lol


My issue is I can't decide between the APS 65mm CAI and K&N Typhoon CAI. Based on my research these appear to be 2 of the more popular CAIs...


So I'm just hoping to get some opioniated responses and personal expiences to help me decide between the 2....

Thanks everyone!!

Your stock airbox will function very well up to 400hp (per unibomber's manifesto). Save your money for something else.

But if you're dead set on wasting money, i vote for APS. I believe them to be a high-quality parts-maker. Maybe consider going short-ram instead.

When I was looking in to getting one, the APS 70mm was the better choice. It is easier to tune with too. Also, check with your tuner and see what he prefers for tuning.

Go to the Proven Bragging Power and the 2.5L threads and do a search for the 70mm. There is TONS of info about the intake there.

The Typhoon isn't a CAI, its a short ram. You are much better off with a CAI, so go with the APS 65. You don't need the 70mm unless you are reaching the end of the MAF resolution, and assuming you are still stock turbo, you are not near that limit.

Well my goal is to squeeze as much outta the OEM turbo as possible... and it seems even though the OEM box is good to 400hp like Unibombers manifesto says, I feel it will be somewhat benificial for where my set-up will be in a couple months with the addition of:

Full-Race Header, Up-pipe, Tial 38mm EWG, and turbo inlet....

So my next power mods are expensive and I wanted to do them all together... so I felt it would be smart to add a CAI now and gain a little on the day of my Pro-Tune.... instead of trying to squeeze it into my budget being established for the next round of mods.

If K&N doesn't make a Typhoon CAI then please explain this:

Do you have a bigger turbo then OEM... taking to my tuner is a good idea. I think I'll do that and see what he prefers.

This is just personal experience, but I had the HKS short ram before, and found an APS CAI cheap from my buddy. The APS felt like throttle response improved a bit, and spool was smoother. You can also hear the turbo spool. I've heard the engine likes the longer intake too, idk. Anything APS gets my approval.

"full race" is a brand and a "header" is an exhaust manifold. Hence Full Race header.

I'm well aware of their reputation coming from a RSX Type S before the STi, and IMHO they are worth the price tag.

The "popular" Typhoon that has all the data logging, dyno testing, and that is known not to mess up the A/F ratios is the 69-8001TWR *short ram*. K&N didn't used to have a CAI P/N for STi's, and according to K&N's web site (http://www.knfilters.com/search/appsearch.aspx), they still don't.

I'm well aware of that, it's not news to me, but thanks for the input. I'm not trying to debate it's existence here. I still have talked to people with it, know it's sold, hence why I'm trying to get a few more personal opinions. I probably should have included Injen too though because it's another popular one.

^^^If you search a little bit, you'll find that the one you linked to is the "bad" typhoon. Its convertable from SRI to CAI and called a complete cold intake, that intake is KNOWN to cause problems along with the Injen. Given this knowledge, from your two choices, go APS all the way.

Well the K&N is listed as an intake that should not cause problems per unibombers manifesto and my searches resulted in people happy with the Injen as well...But as you said APS seems to be the majority vote.

I didn't get the CAI. Didn't work with my FMIC. But when I was looking into it, the easiest CAI to tune seemed to be the 70mm.

Stock turbo.

Yeah there seems to be some confusion on that. The good typhoon is the SRI not the convertable SRI CAI, that one has caused problems for others.

I realized that, hence my edit once I saw the manifold you are planning on getting.

Ahhhh... I see. Thank you for the clarification.


No problem... I should have made it more clear from the start.

Have you considered the prodrive CAI? I'm not debating that APS makes a great product (they most certainly do) just thought I would mention an alternative. from what I've heard and read, the prodrive cooperates with the MAF quite well too.

Just my $0.02
