Spark plug AC DELCO or OEM Honda

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.

Only issue I’ve had is having 2 spark plugs blow out. The first time required a replacement head and the second was fixed with a helicoil. Most reliable vehicle I have owned.

I have an aero 50. I don’t recall what’s recommended on it, but when I was living in the Pacific Northwest, I found that while using premium, it ran significantly better. Smoother idle, better acceleration.

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.

I remember the first time I did anything besides oil, it was spark plugs and power steering fluid on my old accord. Starting it up after had me nervous, second guessing everything I did.

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

Only use the factory AC-Delco 41-987 plugs.

So I went to my uncle who is a part owner of a auto parts supply company and he ordered me 5 Beck Arnley 178-8445 Direct Ignition Coils for my car and 5 ACDelco 41-806 Professional Platinum Spark plugs.

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

I have a 1986 blazer and replaced the spark plugs with ac delco factory spark plugs purchased from napa, about 2 months later I was driving the vehicle and the vehicle had a miss then starting blowing out oil from the Pcv vlave from excessively high crank case pressure after electrode fell out.
