K&N drop-in...feels slower...WTF?
Only "mod" that I've done so far (my IX is only two months old) is to put a drop-in K&N filter (got it as a gift from a friend). But, I've noticed that the strong pull at WOT when the turbo kicks in seems to be less after putting in this filter. I've switched back and forth and the stocker seems better. But, I've seen a dyno chart from a magazine showing that the K&N does produce more power. Anyone experience the same issue I'm having? Maybe the K&N just sucks and I should get a different filter or full CAI, TBE and tune?

More than likley you KN filter had way too much oil on the filter part and stickied you MAF all up. You need to go to the store and by some MAF cleaner and clean it out. I have seen this happen before. The filters come from the factory with way too much oil on them.

Thanks for all the feedback. I just can't figure this one out. The filter was brand new (was still in the sealed plastic wrapping inside the box). So, good to go there. And, having heard that these usually have too much oil, I let it sit out for a full day on top of some napkins to get any of the extra oil out of it before I put it in. I guess it still could have had too much oil. Good suggestion scottatayamaha to check the MAF sensor.
A couple of you have mentioned "clips on the snorkel"...what exactly is that? All the clips on the stock airbox are on correctly.
Thanks again guys.
You know what? Come to think of it...I'm not sure the MAF was affected. I've swapped the stock air filter back in and the car performed normal. Then I put the K&N back in and the turbo response seemed flat again. Then back to stock filter and normal again. I'm so confused...

I've noticed that most k&n's come with too much oil. I've been told to take an old pillowcase, toss the filter inside, and toss it around for a while. Really tho, a drop in filter shouldn't make a noticable difference one way or the other regarding how much power your car makes. Maybe its just a tank of bad gas, or an unusally hot day?

I had a tank of bad gas once after eating some mexican food and noone wanted to stand around me...
Seriously though, not sure what the deal is. It's not that big of a difference, but something I can feel. At this point I'll probably just scrap the K&N and go with a CAI, TBE and get it tuned. Oh well. Thanks everyone.

The clips/ or fasteners they are talking about are the two black plastic ones that hold the snorkle to the radiator support beem. If they are not put back in the snokle will start to lift at speed and choke the air flow going into the box.
Your car will feel like it hit a wall though

The only way to know for sure is a dyno test. The butt dyno does not have the sensitivity to discern a few HP. The placebo effect is most likely the culprit since this is the first time I've heard of the K&N reducing power.
