Hello mates!
I would like to tell me if there are sets of spark plugs 1 step colder than the standar for the focus rs exept densos.
I have heard something about the NGK but not 1 step colder.
Anyone knows?Don't care about the company
Thanks

 

These are new out and can cope with 200-400bhp when I asked Nology

Thanks a lot mate
Do you know which is the part number of nology spark plugs for the RS?
The plugs come to different steps?or it is only one?

 

I'm not too sure on the part number, if you contact the guy from
http://performancestars.co.uk/store/...roducts_id/124
He should be able to tell you the part number, he is quite helpful
They only make one plug for the FRS and told me the heat range is for 200-400Bhp
