Purpose-built for the naturally aspirated 4.2-Litre 1HZ inline 6-cylinder diesel powerplant running integrated emissions systems, this rugged upgrade features an exact factory-matched Exhaust Gas Recirculation (EGR) landing port provision. By replacing the highly restrictive factory cast iron log manifold and reducing power-robbing backpressure, it optimizes exhaust gas scavenging pathways to unlock vital low-to-mid range torque, improve throttle response under heavy load, and ensure full emissions compliance.\u003c\/strong\u003e\u003c\/p\u003e \n\n\u003cdiv class=\"feature-block\"\u003e \n\u003cdiv class=\"feature-content pb-6\"\u003e \n\n\u003ch3 style=\"color: #e60000; font-weight: bold;\"\u003ePRODUCT CONTENTS:\u003c\/h3\u003e \n\u003cul\u003e \n  \u003cli\u003e1 x Heavy-Duty Mild Steel 6-Cylinder Performance 1HZ Diesel Extractor Assembly\u003c\/li\u003e \n  \u003cli\u003e1 x Integrated Precision-Located EGR Emissions Fitting Take-off Port\u003c\/li\u003e \n\u003c\/ul\u003e \n\n\u003ch3\u003eKey Features:\u003c\/h3\u003e \n\u003cul\u003e \n  \u003cli\u003eFeatures a precision-engineered EGR emissions fitting to retain seamless compatibility with factory internal engine emissions circuits\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty mild steel construction structurally built to withstand intense under-bonnet working temperatures, grueling outback touring, and high-vibration off-road tracking\u003c\/li\u003e\n  \u003cli\u003eCustom clearance-mapped inside the chassis layout to easily pass large steering box shafts, independent front suspension nodes, or live-axle control links cleanly\u003c\/li\u003e \n  \u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity past tight engine bay structures and front crossmembers\u003c\/li\u003e \n  \u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure exhaust gas leaks\u003c\/li\u003e \n\u003c\/ul\u003e \n\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\"\u003eA285E\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\"\u003eHeavy-Duty Mild 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\"\u003eToyota 4.2L Inline 6-Cylinder Diesel Only (1HZ Naturally Aspirated Blocks Only)\u003c\/span\u003e\n\u003c\/li\u003e \n    \u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEmissions Configuration:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eEquipped with Integrated Exhaust Gas Recirculation (EGR) Landing Port\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\"\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    \u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWarranty:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e1 Year Manufacturer Warranty\u003c\/span\u003e\n\u003c\/li\u003e\n  \u003c\/ul\u003e \n\u003c\/div\u003e \n\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Drivetrain \u0026amp; Variant Alignment Warnings:\u003c\/strong\u003e\u003cbr\u003e\n1. \u003cstrong\u003eEGR Specific Fitment Requirement:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA285E\u003c\/strong\u003e) features an integrated EGR connection landing point designed explicitly for models requiring active EGR system hook-ups. \u003cstrong\u003eIf your build is an early or overseas non-EGR specification, you will want to source standard part number \u003cspan style=\"text-decoration: underline; font-weight: bold;\"\u003eA285\u003c\/span\u003e\u003c\/strong\u003e instead to avoid needing to block off the landing flange.\u003cbr\u003e\n2. \u003cstrong\u003eStrictly Naturally Aspirated 1HZ Diesel Models:\u003c\/strong\u003e This layout is port-mapped exclusively for the naturally aspirated 1HZ head profile.
