Reviews of AC DELCO parts For Business

I have a 2010 Silverado, and I had a 2011 Silverado. Go with the Delco's. It what your truck was built with, it what she will run best with.

If you do go with something else. Stick with a denso, or an NGK. Avoid Bosch plugs in that truck like the plague or you will start tripping codes.

If excluding Mopar then I would look at ACDelco, Gates or Dayco.

Last time i bought them the ac delcos were around $30 each. If the vehicle is old as shit or im overhauling the brakes id definetly replace them.

41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.

Always buy ac delco OEM alternators not part store crap.

Plugs need to be AC Delco 41993 (no substitution). I've had misfires with other "equivalent" plugs that went away with the correct plugs.

I just recently bought Ac delco tie rod ends because they were made in Japan ‘555’ parts.

My mazda coils were already on 20k miles or so and 1 coil developed some white stuff under the coil , so i grabbed AC Delco 585 coils , installed them and i think in general car runs better but the cold/hot start... With my mazda coils it would start in literally 1-2 seconds , now sometimes 4-5 seconds, it doesnt have dwell remap.

In March of this year I replaced my battery for 98 Civic Ex with an autozone Ac Delco one. With the colder days I started to notice slower cranks if the car had been sitting a day or longer.

I initially got the P0101 code and did the obvious - replaced the MAF sensor. No change, same codes. Goodbye $100.
