When enthusiasts introduce aftermarket audio systems, supplemental cooling fans, air suspension compressors, or high-draw electronics, the stock unit suffers catastrophic thermal stress and severe voltage sag at idle. Internal diodes degrade rapidly from heat soak, leading to dimming lights, ECU voltage-drop codes, premature battery failure, and inadequate power delivery to the coil packs on the \u003cstrong\u003eK24Z3\u003c\/strong\u003e powertrain.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eHand-built in the USA, this heavy-duty 250-amp alternator delivers substantial current reserves across the entire RPM range, maintaining peak output even at low engine speeds. Engineered with heavy-gauge pure copper stator windings, dual internal rectifiers, and high-temperature avalanche diodes, this unit effectively mitigates resistance and dissipates thermal build-up under continuous full-duty cycles. Direct bolt-on mounting geometry guarantees seamless alignment with the factory accessory drive and serpentine belt without housing modifications, replacing troublesome factory numbers such as \u003cstrong\u003e31100-R40-A01\u003c\/strong\u003e and \u003cstrong\u003e104210-5890\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 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;\"\u003e2010-2014 Acura TSX\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;\"\u003eK24Z3 (2.4L) \/ CU2\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;\"\u003e201 hp \/ 170 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;\"\u003e31100R40A01, 1042105890, 210-0644, 11390R, 11390, 31100-R40-A01, 104210-5890, 11390-250A\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\u003e2010 Acura TSX Base Sedan \u0026amp; Sport Wagon 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e2011 Acura TSX Base Sedan \u0026amp; Sport Wagon 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e2012 Acura TSX Base Sedan \u0026amp; Sport Wagon 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e2013 Acura TSX Base Sedan \u0026amp; Sport Wagon 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e2014 Acura TSX Base Sedan \u0026amp; Sport Wagon 2.4L L4\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 CU2 TSX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 2010-2014 Acura TSX equipped with the 2.4L \u003cstrong\u003eK24Z3\u003c\/strong\u003e engine; it does not fit TSX models equipped with the 3.5L V6 (J35Z6).\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my main charging cables?\u003c\/h4\u003e\n\u003cp\u003eYes, executing a \"Big 3\" wiring upgrade with minimum 1\/0 AWG power and ground cables is mandatory to safely carry 250 amps without causing excessive circuit resistance or cable overheating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Caliber\u003c\/h3\u003e\n\u003cp\u003eKeep your performance JDM sedan operating at peak voltage and ignition capability without electrical drop-offs across every gear.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565719355640,"sku":"DS-E9E792HY5","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-acura-tsx-2010-2014-2-4l-1.jpg?v=1791072260","url":"https:\/\/performancechiptuning.com\/de\/products\/high-output-alternator-for-acura-tsx-2010-2014-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
