Once you install aftermarket audio amplifiers, air management compressors, or auxiliary lighting, the OEM traditional wound-stator experiences rapid thermal saturation. At idle speeds—where engine rotation hovers around 650–750 RPM—the factory alternator fails to supply sufficient amperage, resulting in headlamp dimming, battery discharge, and unstable voltage drops that interfere with sensitive engine sensors.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis unit incorporates an advanced hairpin stator design using square copper wire to maximize internal slot fill and drop internal resistance. The increased conductor density dissipates heat more effectively than round-wire designs, minimizing heat soak during prolonged operation. Delivering up to 250 amps of continuous power, this direct-fit unit matches factory pulley offset and plug connectors while keeping system voltage stable at 14.4 volts under heavy accessory demand.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 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;\"\u003e2006-2012 Lexus IS\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;\"\u003e4GR-FSE (2.5L), 2GR-FSE (3.5L) \/ XE20\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;\"\u003e204 hp \/ 185 lb-ft (2.5L) | 306 hp \/ 277 lb-ft (3.5L)\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;\"\u003e27060-31062, 210-0656, 104210-2050, 104210-2051, 104210-4680, 27060-31060, 27060-31061, AL3356X, 11196, 11196R, 11196N\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\u003e2006-2012 Lexus IS250 2.5L V6\u003c\/li\u003e\n  \u003cli\u003e2006-2012 Lexus IS350 3.5L V6\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 XE20 IS?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 2006-2012 Lexus IS equipped with the \u003cstrong\u003e4GR-FSE\u003c\/strong\u003e 2.5L or \u003cstrong\u003e2GR-FSE\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging wiring?\u003c\/h4\u003e\n\u003cp\u003eTo realize the full 250-amp capability under heavy sustained electrical draws, performing a 1\/0 AWG Big-3 battery ground and alternator charge wire upgrade is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus Caliber\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eXE20\u003c\/strong\u003e sport sedan depends heavily on precise electrical signaling to run its direct-injection drivers and electric power steering, making clean, uninterrupted voltage critical to overall performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67621459362040,"sku":"DS-E6X2QFHS5","price":330.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-lexus-is-2006-2012-2-5l-3-5l-1.jpg?v=1791661702","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-lexus-is-2006-2012-2-5l-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
