The Brian Crower Oversized Inconel Exhaust Valves are engineered to provide maximum thermal resistance, increased exhaust flow, and uncompromising reliability for the most demanding street and motorsport applications.\u003c\/p\u003e\n\u003cp data-start=\"485\" data-end=\"918\"\u003eFeaturing a +1 mm oversized head diameter, these valves significantly improve exhaust flow capacity compared to standard-size valves, making them ideal for ported cylinder heads and fully developed high-boost engine builds. Manufactured from premium Inconel alloy, they are specifically designed for engines operating under extreme exhaust gas temperatures where conventional stainless steel valves may be pushed beyond their limits.\u003c\/p\u003e\n\u003cp data-start=\"920\" data-end=\"1274\"\u003eThe undercut stem design reduces overall valve weight while improving exhaust gas evacuation from the combustion chamber, supporting extended RPM capability and greater engine efficiency. Each valve is fully machined and swirl-polished beneath the valve head to optimize gas flow and ensure consistent performance under the harshest operating conditions.\u003c\/p\u003e\n\u003cp data-start=\"1276\" data-end=\"1429\"\u003eSupplied as a complete set of 12, these oversized Inconel exhaust valves are the ultimate upgrade for professional-level drag, drift, and circuit builds.\u003c\/p\u003e\n\u003cp data-start=\"1431\" data-end=\"1613\"\u003eTrusted by professional engine builders and motorsport teams worldwide, Brian Crower valves are a proven solution for unlocking the full potential of Toyota’s legendary 2JZ platform.\u003c\/p\u003e\n\u003cp data-start=\"1615\" data-end=\"1696\"\u003eCarefully selected for builders who demand proven performance without compromise.\u003c\/p\u003e\n\u003chr data-start=\"1698\" data-end=\"1701\"\u003e\n\u003ch2 data-section-id=\"vpcjk0\" data-start=\"1703\" data-end=\"1738\"\u003eWhy Upgrade Your Exhaust Valves?\u003c\/h2\u003e\n\u003cp data-start=\"1740\" data-end=\"1775\"\u003eCompared to factory exhaust valves:\u003c\/p\u003e\n\u003cp data-start=\"1777\" data-end=\"2077\"\u003e✔ +1 mm oversized head increases exhaust flow capacity\u003cbr data-start=\"1831\" data-end=\"1834\"\u003e✔ Premium Inconel construction for exceptional heat resistance\u003cbr data-start=\"1896\" data-end=\"1899\"\u003e✔ Designed specifically for high-boost and high-horsepower applications\u003cbr data-start=\"1970\" data-end=\"1973\"\u003e✔ Undercut stems reduce weight and improve gas flow\u003cbr data-start=\"2024\" data-end=\"2027\"\u003e✔ Ideal for extreme street and motorsport builds\u003c\/p\u003e\n\u003chr data-start=\"2079\" data-end=\"2082\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"2084\" data-end=\"2099\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"2101\" data-end=\"2377\"\u003e✔ Genuine Brian Crower oversized Inconel exhaust valve set\u003cbr data-start=\"2159\" data-end=\"2162\"\u003e✔ Manufactured from premium Inconel alloy\u003cbr data-start=\"2203\" data-end=\"2206\"\u003e✔ Fully machined and swirl-polished under the valve head\u003cbr data-start=\"2262\" data-end=\"2265\"\u003e✔ Dished exhaust valve design\u003cbr data-start=\"2294\" data-end=\"2297\"\u003e✔ Optimized for extreme temperature environments\u003cbr data-start=\"2345\" data-end=\"2348\"\u003e✔ Complete set of 12 valves\u003c\/p\u003e\n\u003chr data-start=\"2379\" data-end=\"2382\"\u003e\n\u003ch2 data-section-id=\"1cgu054\" data-start=\"2384\" data-end=\"2411\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cp data-start=\"2413\" data-end=\"2760\"\u003e✔ Brand: Brian Crower\u003cbr data-start=\"2434\" data-end=\"2437\"\u003e✔ Part Number: BC3303-INC\u003cbr data-start=\"2462\" data-end=\"2465\"\u003e✔ Product Type: Oversized Exhaust Valve Set\u003cbr data-start=\"2508\" data-end=\"2511\"\u003e✔ Valve Material: Inconel Alloy\u003cbr data-start=\"2542\" data-end=\"2545\"\u003e✔ Valve Type: Exhaust \/ Dished\u003cbr data-start=\"2575\" data-end=\"2578\"\u003e✔ Valve Size: +1.0 mm Oversized\u003cbr data-start=\"2609\" data-end=\"2612\"\u003e✔ Head Diameter: 30.0 mm\u003cbr data-start=\"2636\" data-end=\"2639\"\u003e✔ Stem Diameter: 5.97 mm\u003cbr data-start=\"2663\" data-end=\"2666\"\u003e✔ Overall Length: 99.1 mm\u003cbr data-start=\"2691\" data-end=\"2694\"\u003e✔ Quantity: Set of 12 Valves\u003cbr data-start=\"2722\" data-end=\"2725\"\u003e✔ Engine Family: Toyota JZ-Series\u003c\/p\u003e\n\u003chr data-start=\"2762\" data-end=\"2765\"\u003e\n\u003ch2 data-section-id=\"15vxm9q\" data-start=\"2767\" data-end=\"2788\"\u003eCompatible Engines\u003c\/h2\u003e\n\u003cp data-start=\"2790\" data-end=\"2812\"\u003e✔ 2JZ-GE\u003cbr data-start=\"2798\" data-end=\"2801\"\u003e✔ 2JZ-GTE\u003c\/p\u003e\n\u003chr data-start=\"2814\" data-end=\"2817\"\u003e\n\u003ch2 data-section-id=\"icfs9j\" data-start=\"2819\" data-end=\"2830\"\u003eShipping\u003c\/h2\u003e\n\u003cp data-start=\"2832\" data-end=\"2916\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e🇪🇺 EU Delivery: 5–10 Business Days\u003cbr data-start=\"2868\" data-end=\"2871\"\u003e🌍 International Delivery: 7–21 Business Days\u003c\/p\u003e","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":57690351075676,"sku":null,"price":436.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/6300\/6300\/files\/ChatGPTImageMay19_2026_09_17_31PM.png?v=1779214663","url":"https:\/\/jzsignature.com\/products\/bc3303-inc-toyota-2jz-inconel-exhaust-valves-30mm-1mm-set-12","provider":"JZ Signature","version":"1.0","type":"link"}
