Champion 3 Com Spark Plug

Recommended Posts

Can anyone tell me what this plug is equivalent to in the newer series?  I'm not sure but think it was equivalent to a 3X which then went to a C-4 then replaced by C16C and finally to a W-18. I have a set of 4 of these NOS and are a 1-pc design with cad plating.

Just want to confirm how hot or cold it might be before using.

Thanks in advance!

I see them quite plainly, I do not understand why you can not.

 

Best guess as to why you can see them and others cannot is that your picture links point to the photos stored on your computer. FWIW. Pictures have to be uploaded to the forum to be visible to others.

I took a pictures, of part of pages with I phone.

 

Sent it to my email, then copied it to the AACA message.

 

Copying and pasting pictures is not the way to add pics to your posts. 

The way to do it is to save the pics from your emails to your desktop and then drag the image files into the designated area in the forum posting screen. That uploads them to your post.

I can do a tutorial on adding pics to a post here later today if anyone would like one.
