Quick Question About A Plug Heat Rating

[g60-r 0]

afternoon all,

 

i need to run a colder plug in my 1.9 as i'm uping the nitrous bhp metering jets.

 

at the mo i've got NGK BCP7ES. i think i need get BCP6ES to go one grade colder. can anyone conferm this? or is it the other way? Are BCP8ES colder?

 

Cheers

cheers nick, i'm glad i checked with the masses now. i might have ended up with hotter ones. not good as the end up acting as glow plugs

o.k, so now i know i need BCP8ES plugs i can't find some where that sells them. any one know good online sources for plugs? sparkplugs.co.uk was good but didn't have 'em.

 

if i can't find them is there a good substitute plug. or.............. anyone know if BCP7ES plugs will be to hot to run a 50bhp wet shot of nitous with out causing pre-ignition

Try a motorbike shop, they usually have a the full heat range in stock.

 

Saying that, my local motor factor has them all in on the shelf (goes up to 10's I think)
