When demanding auxiliary loads are introduced—such as high-draw aftermarket audio systems, auxiliary lighting, or high-performance air suspension compressors—the stock alternator suffers severe thermal saturation and voltage drops below 12.6V at idle. This thermal breakdown accelerates diode failure, limits charging capacity to the AGM battery, and introduces electrical interference into the sensitive vehicle CAN bus network managing the direct-injected powertrain.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered and assembled in the USA, this direct-fit 250-amp alternator utilizes heavy-gauge hairpin stators, heavy-duty rectifiers with high-amperage avalanche diodes, and high-temp internal components built to withstand thermal stress under the tightly packaged \u003cstrong\u003e2.0L LTG\u003c\/strong\u003e engine bay. The heavy-duty rotor and premium copper windings sustain peak amperage even at standard idle RPM, guaranteeing clean 14.4V power delivery under full electrical draw without triggering ECM charging fault codes.\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;\"\u003e2018-2019 Buick Regal Sportback\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;\"\u003e2.0L LTG Turbo \/ E2XX\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;\"\u003e250 hp \/ 260 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;\"\u003e104210-1960, 104210-1961, 104210-1962, 11682N, TN104210-1960, 11682, 14883, 13592811, 22892569, 22996928\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\u003e2018 Buick Regal Sportback 2.0L L4 Gas Turbocharged\u003c\/li\u003e\n  \u003cli\u003e2019 Buick Regal Sportback 2.0L L4 Gas Turbocharged\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 E2XX Regal Sportback?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2018-2019 Buick Regal Sportback equipped with the \u003cstrong\u003e2.0L LTG\u003c\/strong\u003e engine.
