get rid of the intake or get an air/fuel controller to tune out the problem. do a search here or at IS300.net, you'll find a million posts just like yours with advice.

The IS300 ecu expects an A/F or about 14.7:1. When it deviates too much, it throws a code. With your intake, you have leaned out your A/F since the intake allows better air flow. To fix it your need an AFC.

It has absolutely nothing to do with Stillen being a good or bad intake. In fact it is probably a good intake if it is throwing a code because that means it is leaning out the mixture enough to make the ecu throw the code. If it didn't throw a code, I would say it is garbage.
