wrong size best for ignition parts

I ordered 16 spark plugs. Two were the wrong size and the others were in the box. I sent them all back and ordered elsewhere. The price was great but the build quality etc was poor.

Pros
  • Fine wire center electrode and V cut for better flammability
Cons
  • Ok

Employees or others packing items without proper procedures

I'm very upset. I ordered 16 of the same spark plugs and expected to get all 16 the same. And I got 1 which was not as advertised. NOW I HAVE TO CLOSE DAYLI'S WORK AND STOP AT THE AUTOSHOP TO FIND THE RIGHT PARTS. DO NOT ADVERTISE UNLESS YOU INTEND TO FOLLOW AND GIVE WHAT CUSTOMERS WANT. WE PAY GOOD MONEY AND SOMETIMES GLAD OUR GOODS ARRIVE AND IF THEY DON'T DO WHAT YOU EXPECTED. I'M SO SAD .

Pros
  • Champion Iridium – Maximum Productivity. Premium Spark Plug
Cons
  • Not bad, but...

Good price? Yes, if not fake. Bad performance.

Advantages: Arrived quickly. Cons: I ordered 16"9403" plugs for my Hemi 5.7. Got 13 in good boxes, one in a box with a crushed box and an off center electrode (see pic. A good one is also shown for comparison) and amazing. two wrong parts! (3401 and 3071). Glad I didn't want to work tonight! However pain. The packaging doesn't match the Champion website and the forks don't look as good in real life as the picture on the Mfgr website. old stock? NOT CORRECT? I'll try to find out.

Pros
  • Ground electrode with V-notch for better spark focus
Cons
  • Secret
