Tailored precisely to fit the highly robust, Toyota-derived 1.6-Litre (4A-FE) and 1.8-Litre (7A-FE) Dual Overhead Cam (DOHC) 16-valve inline 4-cylinder engines housed within the LF and LG Nova series, this rugged upgrade replaces the highly restrictive factory cast iron log manifold structure. By dropping heavy engine backpressure and optimizing exhaust gas scavenging velocity, it unlocks vital low-to-mid range torque, sharpens throttle response, and delivers a clean, sporty 4-cylinder exhaust hum.\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 DOHC Extractor Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHighly versatile engineering layout custom-mapped to clear standard carburetted mechanical brackets and Electronic Fuel Injection (EFI) intake runner footprints seamlessly\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-bonnet thermal expansion cycles and typical high-revving 4-cylinder vibrations safely\u003c\/li\u003e\n\u003cli\u003ePrecision-mapped packaging architecture engineered to clear front-wheel-drive (FWD) transaxle casings, radiator cooling fan shrouds, and factory starter motors cleanly\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and removing heavy factory casting bottlenecks\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 gas leaks\u003c\/li\u003e\n\u003cli\u003eEngineered for an efficient workshop turnaround, featuring a straightforward layout that drops seamlessly onto the front engine bank\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\"\u003eA106C\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-Sourced 1.6L \u0026amp; 1.8L DOHC 16-Valve Inline 4-Cylinder Petrol Only (4A-FE \u0026amp; 7A-FE Engine Codes)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eInduction Configuration:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eFits Both Carburettor (Carby) and Electronic Fuel Injection (EFI) System Models\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\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Engine Family \u0026amp; Cross-Platform Variant Alignment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrictly DOHC A-Series Engines Only:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA106C\u003c\/strong\u003e) is designed and flange-mapped exclusively for the Toyota-derived **DOHC 4A-FE and 7A-FE engine profiles**.
