A-Premium Starter Motor for Mazda 2.3L vs ACDelco Gold 337-Series Reman Starter

Buy the A-Premium if you own a 2.3L Mazda 3, 5, 6 or CX-7 and want a new, not remanufactured, starter that drops in with no core return. Buy the ACDelco Gold 337-Series if you have a GM vehicle or a special application that uses the PG260F2/G design and prefer a remanufactured unit built to GM specs. The A-Premium is lighter at 1.4 kW and Mazda-specific; the ACDelco is 1.5 kW, uses a planetary gear reduction design, and owners report exact fit and instant starts, though it ships without the two long mounting bolts.

• Choose the A-Premium if you drive a 2004-2009 Mazda 3, 2006-2010 Mazda 5, 2006-2007 Mazda 6 2.3L Turbo or 2007-2009 CX-7 and want a brand-new 11-tooth starter with a one-year warranty.
• Choose the ACDelco Gold 337-Series if you need a GM-spec PG260F2/G starter for a GM vehicle or special application and prefer a remanufactured unit tested to OE specifications.
