Spark plug question - do i have the correct ones?

[hywy61]

I recently purchased some spark plugs from Rover Connection. Champion RN11YCC - double copper.

Atlantic British site shows part # RN11YC4

Shop manual says RC11 PYP B4

I am not really looking for a big boost in power so I don't care about them being platinum. However I don't want to use incorrect plugs so...... will the double copper be ok?

When I changed my plugs last june I went to the champion double platinum form
NAPA. Engine runs great. I've seen an increase in gas mileage. 01 Disco II

Coulton,
You probably had a misfire problem because of weak plug wires, Bosh Platium Plus 4's need alot of juice and then they will give you some great extra low end power you didn't have before.
