{"product_id":"pa-air-box-hose-1","title":"Perrin Performance 2.4\" Turbo Inlet Hose for the Subaru WRX \/ STI","description":"\u003cp\u003eThe Perrin Performance 2.4\" Turbo Inlet Hose (PSP-INT-401) replaces the factory silicone hose that connects the air filter housing to the turbocharger inlet on 2002–2007 Subaru WRX and 2004–2021 Subaru WRX STI. The OEM hose features a pleated interior that creates turbulence and restricts airflow; Perrin's replacement uses a smooth, enlarged 2.4\" bore to eliminate that restriction. A stainless steel support wire embedded in the silicone wall adds structural rigidity, preventing collapse under the vacuum demands of larger turbos or restrictive filter setups.\u003c\/p\u003e\u003cp\u003eA glass-filled reinforced nylon coupler rated to 400°F mirrors the OEM connection geometry, maintaining correct routing without removing or defeating any emissions hardware. A machined aluminum insert is bonded into the silicone wall at the blow-off valve port for a solid, leak-free connection. The kit includes the inlet hose, nylon coupler, diagnosis connector, vacuum hose, three clamps, four 90-degree connectors, and installation instructions. Available in Black, Blue, and Red to suit your engine bay.\u003c\/p\u003e\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e(1) PERRIN Inlet Hose\u003c\/li\u003e\u003c\/ul\u003e","brand":"Perrin Performance","offers":[{"title":"Black","offer_id":43859979403329,"sku":"PSP-INT-401BK","price":249.75,"currency_code":"USD","in_stock":true},{"title":"Blue","offer_id":43859979436097,"sku":"PSP-INT-401BL","price":249.75,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":43859979468865,"sku":"PSP-INT-401RD","price":249.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/8642\/7713\/files\/e3564444-4afd-4919-a6fe-20f490408b92-800.jpg?v=1777484987","url":"https:\/\/www.awdmods.com\/products\/pa-air-box-hose-1","provider":"AWDMods","version":"1.0","type":"link"}
