if you want to go cheap, check out tC forums and find out what pros and cons come with different brands of intakes. Then go to ebay buy a really cheap one for the tC and modify that to have the gains of all the brands.....if that makes sense. I did that with my celica and I have none of the problems other people have with their intakes...i.e. bogging/CEL and I have the gains that an intake should give. It was also cheap
