Part Number for Copper tipped NGK TR6

[painintheass]

Hello:

I've looked everywhere for a part number on this site, well maybe not to good.

But, I was asked by my tuner to install copper TR6's spark plugs and forgot to ask what the part number was.

I cannot find anything at NGK's site. I bought the wrong copper plugs from Schuck's, they are the copper TR55's, part number 3951. This is the copper plug listed on NGK's site. I do not think they are the same as the TR6's.

Any help for this part number would be greatly appreciated.

Thank you:thumbsup:

4177 are the Tr6s...they are sitting here right in front of me...I run the TR7Ixs now, a little more expensive, but a little smoother idle. They are a heat range colder or two I believe...part # 3690
