Tailored precisely to fit the highly robust, legendary Nissan 3.0-Litre (RB30E) Single Overhead Cam (SOHC) inline 6-cylinder engine housed within the R31 Skyline chassis—as well as the immensely popular Australian Holden VL Commodore platform applications—this rugged upgrade replaces the highly restrictive factory cast iron 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, aggressive Aussie RB engine roar.\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 6-Cylinder Performance RB30 SOHC Extractor Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-bonnet thermal expansion cycles and signature high-rpm inline-6 harmonics safely\u003c\/li\u003e\n\u003cli\u003ePrecision-mapped layout engineered to clear factory brake boosters, steering column universal joints, and inner strut towers seamlessly across both R31 and VL chassis formats\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\u003eSubstantially optimizes low-to-mid range working torque delivery—ideal for improving street throttle crispness, everyday cruising manners, and sports-tuned profiles\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 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\"\u003eA217\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\"\u003eNissan 3.0L SOHC Inline 6-Cylinder Petrol Only (RB30E Naturally Aspirated Blocks)\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\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 Induction Setup \u0026amp; Variant Alignment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrictly Naturally Aspirated (Non-Turbo) Models Only:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA217\u003c\/strong\u003e) is designed and space-mapped exclusively for the naturally aspirated RB30E engine family.
