I haven't researched those other intake pipes enough to give you an informed opinion on how they compare. My initial opinion is they may improve airflow but the amount of air provided thru them may not be as much as the TRD intake. One advantage is the TRD is warrantied for Scion whereas those other intakes aren't. Not to say the TRD intake will be bulletproof but it must have gone through some sort of rigorous development testing to qualify for an OEM warranty even though it doesn't apply to me (Subaru).

HI,

Do you know, normally (or from the history) will Subaru (orSTI) release the upgrade intake for their stock car?
Thanks again.
