Alternator Replacement New 11390N for 2.4L Honda Accord & Acura TSX

In this review of the Alternator Replacement New 11390N, the bottom line is simple: this unit is aimed at owners of 2.4L L4 Honda Accord (2008-2012) and Acura TSX (2009-2014) who need a dependable, direct-fit 130A alternator without the premium dealer price. The reviewer found the alternator to deliver consistent electrical output and an accurate fit for the listed vehicles, making it a practical choice for DIY installers and independent shops. The combination of robust components, factory quality standards and a one year free replacement promise is the main reason to consider this part.

Key Features

• Direct-fit Reference Numbers: Includes compatible numbers such as 11390, 11390N and 1042105890 so buyers can verify fitment for their 2.4L L4 engines.
• 130A Output: The 130 amp, 12V rating supplies stable charging for stock electrical systems and common accessory loads.
• 7-Groove Pulley: Delivered with the correct 7-groove pulley configuration to match factory drive belts and simplify installation.
• Quality Controlled Production: Manufactured in ISO 9001 and IATF 16949 certified facilities, which helps ensure consistent build quality across units.
• Professional Testing: Each alternator is tested with professional equipment to confirm electrical performance before shipment.
• 1 Year Free Replacement: The included one year replacement warranty reduces risk for buyers who want reassurance after installation.

Who It's For

This alternator is best for owners of 2008-2012 Honda Accord 2.4L and 2009-2014 Acura TSX with the L4 engine who want a like-for-like replacement that matches factory pulley and electrical specifications. It suits DIY mechanics comfortable with alternator installation or independent repair shops looking for a cost-effective replacement part that cites multiple OE reference numbers for cross-checking.

Those who need a remanufactured unit with a long-term warranty extension or an alternator with upgraded output for heavy aftermarket electrical systems should look elsewhere; this unit is optimized as a high-quality OE-style replacement rather than a high-output performance variant.
