K&N Typhoon or AEM CAI?

[mattellis]

which one is better in everyones opinion i am ready to purchase either or so i would like to know i want the best one that will peak out my HP.

[B-Stylz]

Typhoon by far.

[Ma1donado]

I agree, the new style typhoon is a great product. And it sounds completely outstanding

[Demisedgabe]

yah thats what im probly gonna get.

[SoCal07Si]

AEM, cuz thats what I have. I havent heard the K&N tho.

[Skyline4life]

K&N I ******* love it.

[I Vtec, do you?]

K&N used to be my favorite until I saw the dyno. If memory recalls, it loses power all the way till like 4.5k RPMs, breaks even till about 7k RPMs, and then makes some average power after that. Not worth it to me.

[SoCal07Si]

damn, loses power?

lol, why would any1 even consider it?

[I Vtec, do you?]

Well, all intakes for the most part seem to lose at least a tiny bit of HP down low. It's just with the K&N, it loses it for a while, and then for another few K rpms it just breaks even, and then it finally gains some. Seems worthless to me.

Lemme try and dig up the dyno

Edit- Here it is



From 4000-6250ish RPMs, it's basically losing power. From 4000-5800ish RPMs, it's losing a considerable amount (12ish WHP I'd say). From 6250ish-7250ish it basically makes none and gains none. From 7250-redline, it gains a good amount. For such a small amount of a range with gains, compared to how big of a range where it's lost/nothing is made, I'd say this intake is good for nothing more than sound.

Compare it to the Fujita SRI (best IMO):



From about 2.5k-4k RPMs, it loses a bit of HP. From then on, it pretty much gains HP all the way till redline (at one or two spots it's about even with stock).

When you mod a car N/A motor for more power, you will lose power down low or up top but will gain on the other. So if its tuned to make power down low you will lose out at the top, if you tune for power up top you lose down low.

Is it worth it? Yes, more power up top is better then down low. Who tracks under 6k rpms?

Plus there have been so many versions of the K&N intake for the Si who even knows which one was dyno tested. This latest one appears to have the filter enclosed.

[kbeeveer46]

So for a newby who barely gets his Si over 5k RPM is something like CAI worth the money? I didn't even know what CAI meant until last night. I heard someone mention that the sound of the engine is better with one? I feel ashamed that I have an Si but don't know anything about cars and mods.

<-- nerdy computer programmer

[B-Stylz]

CAI suck because they have the ability to suck water whenever it rains. Stay away from them.

Don't worry about it. We all started somewhere. If I were to put an intake, I would go with a short ram on this car instead. I have the K & N SRI and when you hear it pass 6K for us with no Hondata program yet, you will shat your shorts.

Lol, you'd have to run through 2 feet of water with no fender well guards to even be remotely at risk.

The previous versions of the K&N typhoon suffered from massive heatsoak. Shield or not, the filter placement is in the back of the engine bay where hot air gets trapped in slow driving conditions. If you're honestly concerned about hydrolock, wait for the Comptech Icebox or get an K&N drop-in.

Not true. I have been here for 2 months is all and have already heard about serveral Si's with issues. Stay away. Just my 2 cents. Obviously everyone has there own opinion.

The only occurence I've read here is those owners who cut/remove their splash guards along the inside fender well, or cut their foglight hole for increased air flow. The filter sits 20" above ground and is surrounded by the fender well guard, bumper, and underbody splash guard. Here's a pic for reference:



The bumper covers the open area in front and below the filter. I am not refuting your claim that hydrolock can occur - only that it's not as widespread an occurence as your posts suggest. If you're inclined to debate otherwise, might I suggest you reference at least 5 threads on this forum where hydrolocking occured from a properly installed CAI.

[B-Stylz]

Who really cares anyway? Just trying to give the guy some advice man. Next time won't bother.

There have been 2 versions of the K&N for the SI.... the one posted in the V2, the newest one... it was on my car... the car has greddy EVO II, DCRH, and the k&N...the before chart was with every thing else the same and the the K&N drop in instead of the typhoon...


I still think it was worth it... I loves muh intake
