When subjected to prolonged heat soak down in the low-mounted \u003cstrong\u003eLS1\u003c\/strong\u003e accessory bracket, factory rectifiers fail and diodes overheat. Upgraded electric radiator fans, secondary fuel pumps, higher-draw ignition coils, and auxiliary audio equipment cause system voltage to sag below 12 volts at idle, causing sluggish starter response, misfires, and headlight flicker.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered and manufactured in the USA, this direct-fit 250-amp unit addresses thermal breakdown through upgraded copper rotor windings, low-resistance hairpin stators, and heavy-duty internal bridge rectifiers. It delivers up to 140 amps at engine idle speeds and a continuous 250 peak amps at operating RPM. It bolts straight to factory engine mount locations, providing a direct replacement for failure-prone OEM numbers like \u003cstrong\u003e10464407\u003c\/strong\u003e, \u003cstrong\u003e10480308\u003c\/strong\u003e, and \u003cstrong\u003e10480342\u003c\/strong\u003e without requiring bracket modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 250-Amp High Output 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;\"\u003e1998-2002 Pontiac Firebird\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;\"\u003e5.7L LS1 \/ 4th Gen F-Body\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;\"\u003e305-325 hp \/ 335-350 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;\"\u003e10464407, 10480308, 10480342, 321-1751, 8242n, 8242-5, AL8723X, 10464070, 1046440, 8242, 8242-250A\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\u003e1998-2002 Pontiac Firebird Formula 5.7L LS1 V8\u003c\/li\u003e\n  \u003cli\u003e1998-2002 Pontiac Firebird Trans Am 5.7L LS1 V8\u003c\/li\u003e\n  \u003cli\u003e1998-2002 Pontiac Firebird Trans Am WS6 5.7L LS1 V8\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 F-Body Firebird?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for all 1998-2002 Pontiac Firebird models equipped with the 5.7L \u003cstrong\u003eLS1\u003c\/strong\u003e V8 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade the primary charging wire?\u003c\/h4\u003e\n\u003cp\u003eYes, running an upgraded 4-gauge or 1\/0-gauge main alternator charge wire to the battery is strongly recommended to safely carry the increased 250-amp load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Pontiac Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eHigh-performance GM muscle requires consistent electrical saturation to maintain optimal spark plug arc duration and precise fuel injection delivery under hard acceleration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565749371128,"sku":"DS-E0WQHD8PJ","price":249.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-pontiac-firebird-1998-2002-5-7l-1.jpg?v=1791073437","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-pontiac-firebird-1998-2002-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
