Just installed K&N
It's awesome. Bought it 100% for the sound, and it is exactly what I wanted: dead silent at a cruise, and the exact opposite when you give it a decent amount of throttle.
Throttle response definitely improved and it just sounds nasty.
Build quality is as expected and fit is pretty good as well. Went together in about an hour.
I'm planning on an in-cabin video under load with stock exhaust later this weekend.

very nice. i was still debating whether to go with the k&n or the joe z. with the k&n, id need to take out the stock airbox, but it doesnt have much else to remove from what im told. the joe z makes easy use of the stock airbox, but we'll see. im still waiting till the holiday bonus checks come out!

This video is actually hilarious - I don't recommend that anyone try to take a video by themselves as it is quite unsafe
I missed a couple of shifts, hit the rev limiter a few times, almost dropped the camera, and gave you great shot of my sexy leg more than once. But what is important is that the sound of the intake came through!

I am going for a JoeZ, toms intake setup, was initially considering this but read bout the heat issues and loss of low end power in hot weather, can anyone verify this? Avg temperature where im at is usually 32-35 centigrade during the day and 26 - 29 Centigrade at night

I live in phoenix and I drove the car around 100 degrees last weekend...probably the last really hot weekend of the year. I noticed no loss of power...maybe it did lose a few, but just like the increase of adding an intake, you'd never notice it if it was there.
Having driven the car for a week now, I'd say that it actually seems more responsive at extremely low speeds (0-10 mph)...the stock intake sort of seemed mushy in comparison.
Does anyone have a reasonable explanation as to WHY they think the K&N would lose power in hot weather? It draws air from the same location as the stock secondary intake (wheel well). The aluminum intake tube might be more conductive of heat than the stock plastic, but at the same time the K&N unit has WAY less mass to retain that heat, as well as a much shorter, less convoluted path to the engine...with way less internal surface area. The stock intake assembly is HUGE in comparison. If heat soak is indeed the problem, then you'd probably have the same issue with the JoeZ or any other aluminum intake.
If it is the loss of ram-air effect at speed from disabling the primary stock intake, then we're not talking heat sensitivity.
I haven't read up on the documented cases of power loss in extreme temps, but I just can't think of any theories that really seem to hold water. I know the intake has been documented to add 5-7 or so hp in normal conditions, so to lose power in heat it has to give up those ponies plus some...makes me think that in these cases there is something wrong w/ the car, the intake, the dyno, or the drivers are imagining something that isn't there. Or, more likely, their car is new, never driven in the heat, and then they added an intake before it got hot outside...and then they noticed their car running differently.

In testing different products for the development of our air box for the IS-F we noticed that the car starves for air. The air ram in the front and secondary are necessary for the car to pull in enough cold air. We were able to get great gains from the K&N with the hood open and a fan pointed straight at it. The temp was around 98 degrees.
Ether way we did get gains for the K&N.

I really hate dyno tests for anything other than a basic tune. They're horrifically unreliable predictors of real world performance.
For the F to C and back to F thing, here's a neat little analog chart:
