Inlet Hoses

Inlet Hoses: The Cheap Pipe That Unchokes Your Turbo

An inlet hose is the pipe that carries air from the intake or airbox into the turbo compressor inlet. Most factory pieces are molded plastic or rubber with a narrow bore and internal steps that restrict airflow right where the turbo is trying to breathe. Swapping in an aftermarket inlet hose opens that path up with a smoother, larger bore, so the compressor draws air more freely under boost. On the same platforms, upgraded inlet hoses also come in recirculating and non-recirculating versions to match your blow-off setup. It's one of the simpler bolt-on jobs under the hood and a common first step when a turbo car feels choked up top.

What ThreePiece Stocks

There are 41 inlet hoses and inlet pipe kits in this category, spanning 7 brands. Perrin Performance leads the range, followed by Torque Solution, Mishimoto, COBB, aFe, Spectre and Alta. Prices currently run from $46 to $429 for what's in stock right now - that's the live range, not a locked-in quote.

Coverage skews strongly toward turbo Subarus, with the WRX, STI, Forester and Legacy GT well represented, plus the Toyota 86 / GR86 and Scion FR-S boxer platforms. There's also fitment across Audi A3/S3, VW Golf and GTI, Honda Civic Type-R, Hyundai Veloster N, Mini Cooper S and Ford. Of the 41 parts, 37 carry specific fitment data covering model years from 2002 to 2025.

How To Choose

Two things drive the pick: your car and your blow-off configuration. On the WRX/STI platform, Torque Solution offers both a non-recirculating hose and a recirculating 3-inch inlet version - match the one to how your BOV or bypass valve is plumbed. The COBB Silicone Turbo Inlet V2 is a silicone piece for 2008-2021 STI.

At the top of the range, the truck and hot-hatch kits like the aFe Ford Raptor 3.5L inlet pipes, the Mishimoto Raptor inlet tube kit and the Mishimoto Civic Type-R inlet pipe kit are multi-piece systems that cost more because they replace more plumbing. Confirm your year and trim before ordering - the bore, valve provisions and mounting differ between platforms.

What Else You Need

An inlet hose works alongside the rest of the intake tract. Pair it with a cold air intake kit or a cold air intake to feed it, and keep a fresh replacement air filter or drop-in filter on the airbox side. On the charge side, look at intercoolers and intercooler pipes to keep the whole boost path consistent. Browse everything in the parent Air Intakes section.
