NGK sell some plugs in two 'flavours' - one 'resistive', one not, and use an additionl letter for the resistive ones in the part number. Might be the same for Champion???

 

See some pictures of the build here. 9000 miles completed!

Champion used to have an "R" denote resistor.

From http://www.spark-plugs.co.uk/pages/technical/champjpg.htm the Q does mean resistor (CDI) - so probably not best fitted to a Caterham
