Covering a highly versatile multi-vehicle application range up to 1984, this heavy-duty manifold upgrade fits the 1.6-Litre and 2.0-Litre engines in the Holden Gemini series, the 1.8-Litre and 2.0-Litre layouts in the Rodeo and Jackaroo 4WDs, as well as the 1800cc Shuttle commercial van lines. By replacing highly restrictive factory cast iron log manifolds, this mandrel-bent assembly significantly minimizes engine backpressure to maximize gas scavenging velocity, unlocking vital low-to-mid range torque and sharper throttle response.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"feature-block\"\u003e\n\u003cdiv class=\"feature-content pb-6\"\u003e\n\u003ch3 style=\"color: #e60000; font-weight: bold;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003ePRODUCT CONTENTS:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel 4-Cylinder Performance Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-vehicle crossover configuration explicitly designed to clear engine bay parameters across classic passenger car, light commercial van, and four-wheel-drive platforms\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust gas velocity and preventing power-robbing pocket turbulence\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque bands—ideal for commercial cargo transport, off-road crawling acceleration, and maintaining steady highway cruising speeds\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-floor or engine bay thermal transitions and demanding continuous operating cycles safely\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping, face distortion, and high-pressure gas leaks\u003c\/li\u003e\n\u003cli\u003eEngineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation window of just 1 hour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"specs\"\u003e\n\u003cul class=\"flex flex-col space-y-2 text-xs\"\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eBrand:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eAdvance Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003ePart Number:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eA440\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eMaterial:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eMild Steel (Standard Finish)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEngine Suitability:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eHolden \/ Isuzu 4-Cylinder Petrol Engine Families (1600cc, 1800cc, 2000cc SOHC blocks like G161Z, G180Z, G200Z)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eComponent Type:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePerformance Exhaust Extractors \/ Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEstimated Fitting Time:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e1 Hour\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWelding Required:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eNo (Direct Bolt-On Configuration to Cylinder Head Face)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Variant Production Run \u0026amp; Generation Compliance Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrict Year Cut-Off (Up to 1984):\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA440\u003c\/strong\u003e) is shaped explicitly to clear engine configurations and body structures for the early Isuzu-built SOHC engine run up to 1984.
