It is the result of years of research, multiple prototypes, and a ground-up design process that has made it one of the most respected intake manifolds in the Subaru performance market.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBuilt without limits.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEvery component is CNC machined from solid billet aluminium, featuring generous bell-mouth runner entries and thick-wall polished mandrel bent tube components assembled with high-end TIG welding. The result is a manifold rated to 100psi of boost pressure — a level of structural integrity that no cast or fabricated alternative can match.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eStreet performance, without sacrifice.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe plenum volume and runner length of the Street version are specifically tuned for strong low and mid-range torque while still opening up power higher in the rev range. Critically, the plenum volume remains compatible with the factory air conditioning system, making this the right choice for any build that needs to remain comfortable and streetable day to day.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTesting on completely stock engine, turbo, and fuel system setups has shown approximately 9% gains in both torque and power. The same percentage gain has been recorded on highly modified setups running E85, demonstrating the manifold's capability across a wide range of build levels.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor builds requiring more top-end power, the Street version can be supplied with shorter billet TGVs. 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 that does not ask you to compromise.\u003c\/p\u003e","brand":"Process West","offers":[{"title":"Silver","offer_id":51583532073239,"sku":"PWIM005","price":2850.0,"currency_code":"AUD","in_stock":true},{"title":"Black","offer_id":51583601377559,"sku":"PWIM005B","price":3000.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/0570\/1399\/files\/1_218e16fa-5f81-4611-afbc-1de360ffc7b6.png?v=1763115551","url":"https:\/\/processwest.com.au\/products\/intake-manifold-cable-throttle-stock-orientation-subaru-99-00-wrx-sti","provider":"Process West","version":"1.0","type":"link"}
