{"product_id":"4b11t-35mm-stainless-steel-intake-valve-set","title":"4B11T 35mm Stainless Steel Intake Valve Set","description":"The Brian Crower BC3130 is an intake valve set engineered for the Mitsubishi 4B11T engine platform, specifically for the 2008-2015 Lancer Evolution X and 2009-2015 Lancer Ralliart. These stainless steel alloy valves serve as a robust alternative to factory components, providing increased resilience against the thermal fatigue and mechanical strain associated with high-boost, forced induction, and high-RPM operation.\n\nConstructed from high-tensile, chromium-based stainless steel, these valves feature a precision back-cut on the head to reduce mass and optimize airflow. The set maintains the OEM 35mm head diameter, allowing for direct-fitment into factory-prepared cylinder heads while ensuring compatibility with existing or aftermarket 7-degree locks.\n\nThis is a professional-grade component rather than a casual drop-in upgrade. Installation requires a qualified machinist to perform a multi-angle valve job, verify installed height, and check for proper valve seat sealing. The manufacturer strongly recommends pairing these valves with matching Brian Crower valve springs and titanium retainers (e.g., BC0255) to ensure systemic valvetrain integrity and prevent issues like valve float or coil bind. For optimal safety and performance, professional assembly is non-negotiable.","brand":"Mitsubishi","offers":[{"title":"Default Title","offer_id":52689227448632,"sku":"BC3130","price":190.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687067604.jpg?v=1784903701","url":"https:\/\/store.motormia.co\/products\/4b11t-35mm-stainless-steel-intake-valve-set","provider":"MOTORMIA","version":"1.0","type":"link"}
