PGParts Starter for Chevrolet Impala 3.6L V6 vs ACDelco 12645298 GM Original Equipment Starter

Buy the ACDelco 12645298 for a 2012-2016 Impala 3.6L or any GM vehicle it lists, because it is a new GM Original Equipment part with a 4.7 rating from 15 owners. Buy the PGParts Starter 1 only if you drive a 2017-2020 Impala 3.6L, which the ACDelco listing does not cover. The ACDelco is the stronger part on paper: new components, aluminum mounting block, 6.6 lbs, and GM's own durability claim. The PGParts is a narrow-fit aftermarket unit with no rating and no owner feedback.

• Choose the PGParts Starter 1 if you own a 2017-2020 Impala 3.6L and need a 12V, 1.4 kW, 12-tooth clockwise starter that matches the later car.
• Choose the ACDelco 12645298 if you want a new GM Original Equipment starter with a proven rating and your Impala is a 2012-2016 3.6L or another listed GM fitment.
