Just installed a K&N CAI in my xB [review / pics]
I just installed a K&N Cold Air Intake in my Scion xB. Below is the review that I posted in the Parts section of Scion Life. I'm also including a couple pictures of the finished product. Enjoy.

I've trusted K&N products for many years on my other vehicles, so based on that plus the claimed dyno numbers, I chose it over the AEM CAI for my Scion xB. I paid $200 for it through Crutchfield.com.
Installation of the CAI was fairly straight-forward. K&N did an excellent job with the instructions that were provided. The only thing I found that differed from the instructions was that I used a few more tools than they called out.
My only complaint about the K&N CAI is that they should have put a small bead around the end of the tube where you install the air filter. Once the filter is installed, it is hanging down from the tube in the vertical position. A small bead around the tube to provide a positive stop between the filter flange and the clamp would give me a little more confidence that the filter won't fall off while I'm driving. However, if you make sure you get the clamp on there nice and tight; I don't think you'd have to worry about it.
Speaking of the filter installation, one tip I can offer to make the job easier is to remove the foglamp hole cover (only on xB's without foglamps) to gain easy access to the clamp through the foglamp hole. If you have a foglamp in the way, and don't want to remove it, then you can still get to the clamp from the under-side, but it will be a lot more difficult.
As for performance, I believe that it performs just as K&N claims. If you look at the K&N dyno chart, you’ll notice that added horsepower comes into play starting around 3500 RPM. So don’t expect this product to help a lot right off the line, but it does make a significant difference on the highway when you want to speed up to pass a car. It also seems to have an overall better throttle response.
Another nice thing about this CAI is the sound that it produces. It’s loud enough to differentiate it from stock, but not too loud to become annoying. In general, it makes the xB sound a lot more aggressive when accelerating.
In summary, I feel that the K&N Cold Air Intake for the Scion xB is well worth the cost, and it delivers performance just as promised.
