"ricer sites"? what do you mean? considering that a corolla is technically a "ricer" wouldn't you want parts from "ricer sites"? for headers, ebay is really the only place to find 4afe headers. just don't get the "racing headers", get the known brands, like pacesetter, obx or mimo. an aftermarket intake wont get you much horsepower, especialy in these engines since they aren't moving much air to begin with... but you could get a kit off of ebay as well, but i would recommend getting one from injen or hks. a pipe is a pipe, but the filter is not very good quality. it's very easy to fabricate as well, so don't just buy ebay crap if you can't find a good intake, i would just get a pipe, fabricate it and buy a standard filter form some good company.
