Designed to cope with the heat and boost pressure of turbocharged use, these 5‑ply silicone couplers offer a stronger, longer-lasting alternative to the OEM rubber pieces while keeping fitment and routing similar to stock. The result is a more reliable intercooler connection that helps maintain boost pressure and support consistent on-road and track performance.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from aramid-reinforced silicone, the IAG couplers are engineered to hold their shape under load and resist cracking, swelling, or softening over time. Compared to the factory 3‑ply couplers, the 5‑ply design provides additional wall strength and improved clamping security, particularly important on vehicles running higher boost levels or exposed to prolonged under‑bonnet temperatures.\u003c\/p\u003e\n\n\u003cp\u003eThe turbo outlet coupler is specifically shaped for tight-fitting top mount intercooler installations on Subaru platforms. A moulded clamp holder helps keep the clamp correctly positioned as you install the coupler, reducing the chance of misalignment or slippage. An integrated pry point offers a purpose-designed spot to use a screwdriver or small pry bar, which can be especially helpful when working in confined engine bays, and helps protect the silicone from accidental damage during installation or removal.\u003c\/p\u003e\n\n\u003cp\u003eTo complement the upgraded couplers, IAG includes four heavy-duty lined stainless steel clamps in the kit. These clamps feature bead-rolled inner edges to improve strength and resist deformation as they are tightened, along with a smooth inner liner that helps prevent cutting or scoring of the silicone. This combination of robust couplers and premium clamps provides a secure, durable connection at both the turbo and throttle body.\u003c\/p\u003e\n\n\u003cp\u003eThe kit is supplied as a complete top mount intercooler coupler solution, including the turbo to intercooler coupler, throttle body coupler, and all required clamps. It is suitable for 2001–2021 Subaru STI models, and also fits 2001–2007 Subaru Impreza WRX and 2003–2008 Forester XT models when equipped with an STI top mount intercooler. Available in black, red, or blue, the IAG “Stock” Top Mount Intercooler Coupler Kit offers both functional and visual improvements for your engine bay while remaining straightforward to install for anyone familiar with basic intercooler or intake work.\u003c\/p\u003e","brand":"IAG Performance","offers":[{"title":"Black","offer_id":58324585382191,"sku":"IAG-ENG-2350BK","price":249.95,"currency_code":"AUD","in_stock":true},{"title":"Red","offer_id":58324585414959,"sku":"IAG-ENG-2350RD","price":249.95,"currency_code":"AUD","in_stock":true},{"title":"Blue","offer_id":58324585447727,"sku":"IAG-ENG-2350BL","price":249.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/IAG-ENG-2350.jpg?v=1786583752","url":"https:\/\/www.prospeedracing.com.au\/products\/iag-stock-top-mount-intercooler-coupler-kit","provider":"Pro Speed Racing","version":"1.0","type":"link"}
