What benefits does the Iridium spark plug offer?

It offers excellent engine idle stability, reliable cold starting, quick acceleration and smooth performance.

What are ACDelco GM Original Equipment parts?

ACDelco GM Original Equipment parts are designed, engineered and tested to rigorous standards, and are backed by General Motors.

When I ordered this I ordered 4 thinking it was only 1. I got 4 boxes of 4. So yes it is 4.

Do I need Antiseize with these?

Most spark plug manufacturers recommend you DON’T apply anti seize compound. It can cause you to overtorque the plugs when installing.

Is this for an individual spark plug or is this a set of four? It seams too cheap for four spark plugs.

It is for an individual spark plug!

Will I see any improvements in performance over the factory spark plugs?

These spark plugs were identical to the factory plugs on my Malibu 1.5T. I did not see much improvement but the plugs I replaced had 60K miles. Iridium plugs last a long time, 100k in non turbo engines.

How many comes In a pack?

I was able to find these in a 4 pack from this seller.
