NGK DCPR9EIX question.

[Kid1620]

I know it's been beatin to death already but can anyone running the DCPR9EIX tell me what size the hex bolt on it is. The DCPR8EIX is a 5/8 I believe and I believe the DCPR9EIX is a 3/4. Did anyone have trouble installing them.

 

[snrusnak]

Not sure. I had the 8's then switched to the 9's, didn't even realize it was a different size. I don't think they are different, actually, as I don't remember using a different spark plug socket. I had no trouble.

I'm pretty sure they're the same size.

 

[Kid1620]

Thanks but I'd like to be 100% sure they're the same size before I upgrade.

5/8

 

[snrusnak]

Why does it matter? Do you not have both sockets?

 

[Kid1620]

Anrkizm: motorcyclesuperstore.com says that the DCPR9EIX is 3/4.

Snrusak: Just wanted to be sure there wasn't a clearance problem or something

[snrusnak]

don't know, but I have the 9EIX's in mine, and they went in fine.

 

[Kid1620]

Got it thank anrkizm and everyone else

I installed the 9's(2316) with a 5/8. I think Anrkizm is on to something in the picture above. Two different NGK, both 9's. Might want to make sure you have the right plug.

5/8

The chart above tells you what all of the numbers mean.
