Price

I got these for a good price and they were the right ones for my car very pleased

Original equipment iridium plugs at an amazing price from amazon .

Since it was so cheap that i thought the price was for one individual plug so i bought four since i needed 4 only.

Received 4 spark plugs for an exceptional price.

Shipping

Plugs arrived promptly and were installed without any fuss.

Product arrived a couple days early and was wrapped in bubble wrap inside the envelope.

The trouble comes from shipping spark plugs.

It's not the plugs fault, but beware shipping items like this.

Packaging/appearance

The actual sparkplugs were in perfect condition along with the boxes they came in.

Looked these up on amazon and they were the right numbers.

This was a bulk acdelco package, said 4-41-156 right on it, each plug inside was individually packaged.

These are junk now because it appears the box was mishandled pretty badly, and you do not want to use mishandled spark plugs.
