Custom-configured explicitly for the bulletproof 2.6-Litre Electronic Fuel Injection (EFI) 4-cylinder engine, this precision performance upgrade replaces the highly restrictive factory cast iron log manifold. By optimizing exhaust gas scavenging velocity and significantly dropping backpressure, it maximizes low-to-mid range working torque and improves throttle response—essential for hauling, off-roading, and daily work truck duties.\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 EFI Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and eliminating heavy factory casting restrictions\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque delivery—ideal for improving off-road crawling capability, highway overtaking, and commercial utility towing capacity\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-bonnet thermal transitions and demanding 4WD operational heat 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 exhaust 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\"\u003eA442i\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 2.6L (2559cc) SOHC 4-Cylinder Petrol Engine Only (4ZE1 Block Code)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eFuel Delivery Layout:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eElectronic Fuel Injection (EFI)\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 Oxygen Sensor Fitment \u0026amp; Installation Compliance Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eOxygen (O2) Sensor Modification Required:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA442i\u003c\/strong\u003e) is designed to suit multiple trim runs of the 2.6L 4ZE1 engine. \u003cstrong\u003eFor vehicle variants equipped with a factory exhaust oxygen sensor, a mounting hole must be marked and carefully drilled into the collector assembly prior to final vehicle fitment\u003c\/strong\u003e to accommodate your standard sensor hardware.\u003cbr\u003e2. \u003cstrong\u003eEngine Block Restriction:\u003c\/strong\u003e Specifically engineered for the architecture and port patterns of the fuel-injected 2.6L block.
