#1 - What is the difference between Champion RC10YC, RC10PYC and RC10WYPB4?

Using the Champion Numbering System, we see that the last set of letters toward the end of a part designates various plug features, including metal types. RC10YC features Champion's Copper Plus design, their standard nickel spark plug. RC10PYC has the addition of a platinum tipped electrode. RC10WYPB4 has the addition of an iridium tipped electrode.

We can confirm by comparing the specs for these parts, which shows RC10YC has nickel electrodes, RC10PYC has a platinum tipped center electrode, and RC10WYPB4 has a platinum tipped ground electrode, and iridium tipped center electrode.

#2 - When searching for 3032, there are 2 options. What is the difference between Champion 3032 and 3032-2?

Though the specs tab can provide key difference in part features and dimensions, the part title and bullet points can provide additional help in packaging differences.

  • While Champion 3032 is sold in standard packaging, 3032-2 is a 2-pack of plugs solid in blister packaging.
