When aftermarket demands like high-draw car audio amplifiers, auxiliary cooling fans, or high-output lighting are introduced, the factory unit suffers from severe diode heat soak and rotor stator saturation. This leads to critical voltage sag below 12.6 volts at idle, dimming headlights, slow starter rotation, and premature battery degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high current delivery, this replacement features a high-output hair-pin style copper stator winding and a heavy-duty rectifier bridge designed to dissipate internal heat effectively. Delivering up to 250 amps, it stabilizes primary system voltage at 14.4 volts even under high-load idle conditions. Constructed with a direct-fit cast aluminum housing, it utilizes OEM mounting tabs and factory harness interfaces to replace stock part numbers such as \u003cstrong\u003e4S4T-10300-AC\u003c\/strong\u003e and \u003cstrong\u003e5S4Z-10346-A\u003c\/strong\u003e without custom mounting brackets.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x High Output 250-Amp Alternator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2005-2007 Ford Focus\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eDuratec 20 (2.0L) \/ C170\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e136 hp \/ 133 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e4S4T-10300-AC, 4S4Z-10346-AB, 5S4T-10300-AB, GL-631, GL-657, GL-676, GL-926, 8406, 5S4T-10300-AC, 5S4Z-10346-A, 6S4T-10300-AD\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2007 Ford Focus 2.0L (Automatic Transmission, Federal \/ Non-California Emissions Only)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the C170 Focus?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2007 Ford Focus equipped with the \u003cstrong\u003eDuratec 20\u003c\/strong\u003e 2.0L engine. \u003cstrong\u003eFits automatic transmission and federal emissions models only; does not fit manual transmission or California emissions (PZEV) models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my wiring for this alternator?\u003c\/h4\u003e\n\u003cp\u003eTo safely transfer the full 250-amp output and avoid voltage drops, upgrading the positive B+ charge lead and primary ground cables with heavy-gauge wire is strongly recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Compact Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe electrical draw without sacrificing daily commuter reliability, this unit ensures your Ford's ignition, sensors, and aftermarket electronics perform at optimal operating voltages under all operating temperatures.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67621504876792,"sku":"DS-EUUGF01VG","price":236.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-ford-focus-2005-2007-2-0l-1.jpg?v=1791662964","url":"https:\/\/performancechiptuning.com\/de\/products\/high-output-alternator-for-ford-focus-2005-2007-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
