K 7 N Typhoon misery nightmares continued
As many of you know I have repeatedly suggested that the K & N Typoon intake system really sucks beacuse as i have determined it causes the Evo to run excessively RICH and you have no power
It is the only major manufacturer intake system to cause this overly rich condition
over time I have developed reflashes which compensate for this rich condition and the cars can run acceptably with the K & N Typhoon after they are tuned
Today member Pyrowithin came for a custom tune with a K & N Typhoon intake tube and the Buschur air filter attyached
Through this trial and tribulation we have determined now that the intake metal tube section is the part of the K & N typhoon which causes the overly rich condition and not the air filter part
Thanks for floowing along another day of maddness
PS - the car ran so well when I was done that the clutch became useless - time for a new clutch

Why would you bother when we've been saying all over EvoM that it's the worst intake for the Evo? Why do people keep BUYING IT? Please get rid of it and just use the regular cone filter along with your flash.
I wish I would have known about that crappy intake before I bought it 2 years ago. what a waste of time and money. I threw mine away and kept the K&N cone filter. but that pipe is a piece of you know what.
Take a look at the inside of the intake tube, you will see the problem. The flap they inserted for the BOV return restricts the diameter of the tube by MORE THAN 60%!!! You may try removing the flap to correct problem. The filter is a nice piece, K&N are innovators in that area.
But yes, the stock air box with a drop in filter from K&N, HKS, ETC. will be enough for most applications.
I learned the hard way too. K&N is a good company and Ive had a lot of luck with thier products in different applications. Plus, when you buy an evo, they dont tell you "check out evom.net, there you'll find what works and what doesnt." So dont yell at those whove made the same mistake. Its not a cheap piece.
Another solution is to re-install your stock air intake tube and use K&N adapter and filter. A lot of engineering has gone into the factory pieces. The evo was never intended to be anything but a performer.

I think K&N is a great company too. I had their intake on my civic si. and it worked great. I just think they jumped the gun when it came to producing the intake for the evo. The smaller pipe, the fact that the turbo spools one way and the air is swirling another. K&N is a great company but the intake for this car was not designed properly.

hey Al,
have you tried to take out the flap and retest?? i just dont see how a tube could cause a overly rich condition, then again i dont have the tools nessissary to measure the differences. since the tube is basically the same as everyone elses, with the exception of the small flap, i wonder if that is causing the problem. i know that K&N suggests to turn the MAS upside down to help, but does it cure the overly rich-loss of power problem?? i took mine off also and went back to the stock airbox/filter and the car pulled alot harder. never had any stalling issues either.
as mentioned above, yes it is an expensive "mistake". although it has worked for some, it may not work for others.
does the HKS RS intake have that flap in the tube?? how is the curvature of the tube compared to the K&N?? is it the same length and diameter?? lets compare....
we should be trying to figure out what is wrong with it instead of just pawning off that is it just a pile of junk and say that the "HKS RS intake performs the best for my flashes". lets take your knowledge and make what is bad-good. if you test the intake pipe with the flap in it against the HKS RS of course it will not perform, but if you take the K&N pipe and dremel out the flap and retest, you may have solved the long awaited fix for what most of us have in our attics, garage floor, trash can, etc.
you have the knowledge, test equipment, and time. try it and see. we all will thank you.

Now I know I am no Al, cause he is way smarter ...but I tried taking out that flap in the tube and it didn't really help. I still lost power in the top end. It died after 5500 rpms. just my personal experience.

I was just happy to narrow down that what ever sucks on this unit is actually located in the metal tube itself
