Generous bell-mouth runner entries, thick-wall polished mandrel bent tube components, and high-end TIG welding combine to produce a manifold rated to 100psi of boost pressure. It is a level of construction that cast and fabricated alternatives cannot replicate, in strength, precision, or finish.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eReal gains, across all build levels.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOn stock engine, turbo, and fuel system setups, testing has recorded approximately 9% gains in both torque and power. On heavily modified builds running E85, the same level of improvement holds. The plenum volume and runner length are tuned for strong low and mid-range torque with continued power delivery through the upper rev range — and unlike many performance manifolds, the plenum remains fully compatible with the factory air conditioning system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor any street build that needs to perform hard without sacrificing comfort, this is the correct solution. For builds requiring more top-end power, shorter billet TGVs are available. Custom throttle flanges are available on request.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe street manifold built to last, perform, and impress at every level of modification.\u003c\/p\u003e","brand":"Process West","offers":[{"title":"Silver","offer_id":62794694066257,"sku":"PWIM002","price":2850.0,"currency_code":"AUD","in_stock":true},{"title":"Black","offer_id":62794694099025,"sku":"PWIM002B","price":3000.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/files\/1_c9591a51-abbd-474a-8d3d-ad4cd709db78.png?v=1791064031","url":"https:\/\/longboostperformance.com\/products\/intake-manifold-dbw-stock-orientation-subaru-06-21-wrx-sti","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
