Reviews of AC DELCO spark plug

I recommend nothing with platinum. I've had problems with those in my 1980 gbody with a 305. I just keep it simple with old ac/delcos now. Keep it simple for less problems.

These look like knockoff acdelco plugs.

Use only AC DELCO ignition components for GM vehicles, and that includes spark plugs. The factory plugs work perfectly.

AC Delco CR43TS.

Copper plugs are actually the best for performance, precious metals just last far longer.

I'd use the original equipment AC Delco plug. Rockauto has them for $6.31 each, with a $3 per plug rebate offered.

At least with double iridium ACDELCO on the c5. It’s 100k intervals.

AC Delco double platinum spark plugs belong in that engine.

The new plug is AC Delco 41-156. Cannot tell any difference in my Gen 2 after replacing plugs. It ran fine before and did afterwards as well.

I use them. Just replaced a set after they'd lasted 90,000 miles, only to rule out a very very tiny misfire count issue I've noticed lately. I might get a coil pack now, but those original plugs surely would have lasted longer (they say they should last for 100k).

Bought a set of iridium plugs that were wasted after 15k miles. Amazon gave zero fucks. AC Delco gave zero fucks. The scum bags who sold them changed their name and keep selling.
