Well, the title says it all. I have a few questions for the K&N Typoon owners here. I have been checking out intakes for my RS2 xA and have narrowed my final choices down to two:

K&N Typoon CAI
-or-
AEM CAI (Scion option type)

My first choice is obviously the K&N but I have two minor concerns:

First would be how well the drycharger works. Judging by my profile, you can tell I live in the Northeastern part of the country where the weather outside can be frightful, and my main concern is the intakes ability to suck in water. I have read in several posts that the drycharger is there to help keep dirt and water away from the filter element at minimal loss of performance. Has anyone had any experience or know for a fact that this works well?

Secondly, for the fellow xA owners with the K&N. Is there an issue with the foglight coming in contact with the filter like there is with the AEM? I use my foglights in adverse weather conditions, both night and day, and they also function as driving lights at night and I'm not in any mood for abrasions or heat damage to the filter.

Finally, has anyone with an aftermarket intake had any problems at a dealership when they bring in their xA/xB for service of any kind?

I know rather specific questions but they are minor issues that I was curious about.

 

I would recomend the Injen Cold Air Intake............

 

i have the k & n and it performs pretty well and the sound is excellent

 

and the drycharger seems to do its job and its been rainin alot in the past few weeks

 

Go K&N.

The drycharger is effective.. it will protect from little splashes but of course if you decide to submerge your car into a puddle for any longer than a second, you run the risk of hydrolock. But then again, the intake is pretty well protected by the underbody. Pretty enclosed.

Another reason to go K&N is because it's CARB legal now. I don't know about the AEM, but there are two versions. The dealer version which is CARB legal and some second one that actually isn't CARB legal last I checked. Something things to keep in mind.

Oh yea, and the K&N has the highest dyno gain.

I had aftermarket foglights (Hella Optilux 2500) which are larger than stock because of the angel eyes and had no problem with the fog lights or wiring hitting the filter.

 

go K&N and if your really concerned about hydrolocking buy a universal bypass or a AEM one all you do is cut the pipe and slip it on nothing to it....oh and the sound is awesome from the typhoon

 

Thanks guys, greatly appreciated.

I will be going with the K&N, I just have to choose a color. :D

 

plus, the injen blows because it bends like ~~~~~~~/\/\/\~~~/\/\~~~....well not really, but it DOES have a lot of bends, the K&N has only two bends that arent even...bendy.

 

Best description ever!

 

yeah go k&n! i love mine for sure! sound is premium- i dont even want an exhaust

I'd say K&N, they have a great track record

 

I have K & N also. I'd say go with K & N.

 

Go with the K and N!!! The xA has a better design than the xB I think. :D

 

I have the INJEN CAI sitting here waiting for install, but a new line of intakes will soon be out, and I will be running that set-up.

xA design is better than the xA!?!

 

The xA Kand N goes straight down where as the xB has to travel some distance to get to the cold air. :D

 

If your Injen is "blowing", you hooked it up to the wrong end of the car....

Do you really think those bends are a detriment and NOT part of the design? There is a thread on here somewhere with a guy who designs intakes talking about the process of finding the optimal length for the pipe and then fitting it within the space you have.

 

yeah but optimal length could be a completely different thing from optimal amount of bends! i cant believe blowing or sucking air through a tube that has 5+ bends will be any faster or easier than an equal length pipe with only 2 bends...

of course, there is the argument that too much flow is a bad thing- like at lower rpms where i guess you could lose some torque... but for high end power- definitely the shortest and straightest pipe would be best (that would be the closest to no pipe at all) and lets the engine take in more air when it asks for it.

to me, the k&n seems to have the best of every design...

#1 filter is placed in a low-heat area next to the bumper (unlike injen IS)
#2 short pipe, only 2 bends at only around 60degrees from straight each. (unlike AEM & injen RS)

i was all about the injen IS for a while... but when i saw how simple and robust the k&n is- my choice was made!

Well, the pipes aren't an equal length. It's not like sucking water through a tube, it's not in a vacuum so after you've started the car, the tube is gonna be filled with air. It's not like the engine gasps for air while its trying to draw it down the longer tube. Plus, the added benefits of cooler air come into play...

 

definitely agreed... cooler air is pivotal in the equation- the cooler the air, the more dense it is. the more dense it is, the more oxygen the engine gets.

one other thing to note is the longer air is exposed to a warm/hot pipe the hotter the air will become. great thing about the k&n is hardly any of the piping runs through the engine bay- it goes directly down into the bumper. it also interests me how the injen IS kind of mimics the stock piping with the bend back towards the rear of the engine, and the k&n takes a completely different direction straight away from the engine. i wonder if this has anything to do with the Injen IS getting such good dyno numbers in that dyno comparison among intakes.

still though, my heart lies with k&n

they did seem to follow the stock design probably to maintain the original flow caracteristics of the OEM piping while allowing a slightly cooler air charge in but the the injen intake is flawed....that much piping right next to the engine will lead to tons of heat soak in the intake unless you wraped it in header wrap to block alot of it i dont see how it is all that better for performance. to me i think and this is just MY OWN OPINION but the design of the typhoon is much better than all the others and quality is top notch plus the sound is friggin awesome... the look on alot of peoples face when i pull it to redline is like DAMN....what are you runnin in that lil thing?.......PRICELESS
