The Agency Power aluminum intake pipes for the 2007-2007 Subaru WRX and STI are 3” in diameter to allow more, and smoother, airflow to your turbo. Its simple design allows you to easily install this hard pipe under your manifold with minimal work. Unlike competitor's silicone intake tubes, there is no flexing, collapsing under pressure, or fitment issues. Agency Power's 02-07 WRX & STI intake pipe was designed to use all your factory hoses. Agency Power turbo inlet pipes are purchased with either, 2.5” silicone couple for a stock WRX/STI turbo, or with a 3” silicon coupler for larger, aftermarket turbo compressor inlets (select coupler size and pipe color below). Each Agency Power inlet tube kit includes all necessary hardware, silicone couplers and hose clamps. The Agency Power WRX/STI inlet pipes will fit most short ram and cold air intake kits, as well as the factory intake pipe.
The 3" turbo inlet will NOT fit the factory turbo.
This inlet will require you to bypass the PCV system when installing on 2004+ Subaru's.
