NGK Spark Plug Cap Confirmation - 81 450E

[pete]

Hi guys, just want to confirm that NGK VB05F spark plug caps should be good to go for my 81 450E? I have shiny new B8ES plugs ready to go and my right plug cap is knackered, so I want to replace both at the same time.

I've searched and found the threads regarding interpreting the plug cap numbers which is what leads me to believe this is the right type...

Hi,

Yes, those will work. But do you really need the longer plug caps? Are your plugs that deep in the head? On my bike, the XB05F are what I use on the outside spark plugs. I use the VB05F on the inside cylinders where the spark plugs are more recessed.

Thank you for your indulgence,

Thanks BassCliff!

I'm not sure to be honest, just going by what others looked at I figured the longer would be better.

I can't seem to find the comparison of V vs. X in this application or to compare with the stock plug caps...

However, if XB05F are fine on the outside of an 850, they should definitely be fine on the 450 as I have no inside plugs to worry about

Thanks again BassCliff.

I saw your thread on your replacements already which was very helpful, but didn't clarify for me which length to go with. Will be very helpful when I do the replacement though!

Thanks for the second link, that cleared it up nicely and the XB05F will be fine.
