Hi John, I've had a slight misfire so I went to my local spares shop today to replace the old NGK plugs. The BP6ES has been replaced by a newer model, but neither I nor the guy on the desk were sure they were exactly the right type. When I told the grey-haired shop owner what car they were for, he pulled out a pack of Champion RN9YC -- apparently the Champion N5 was a racing plug (?) and the new version is the RN9YC (latest version of the N9Y). They were £2.50 a go, and the Draper 14mm plug wrench (part no. 12243) was a fiver, so hopefully I'll cure that misfire by tea-time...

I'm pleased to report the new Champions are... champion. Car is running nice and smoothly once again. Changing the plugs on cylinders 4 and 6 is a bit awkward with the straight tubular plug wrench, due to the closeness of some of the components, but mission accomplished  |

The "R" stands for the inbuilt resister which I think all plugs have to have now to prevent spikes tha damage the black boxes on modern cars.
I prefer NGK or Bosch as whenever I have bought Champions one out of 6 (or 8) has always failed early.
Spark-plugs.co.uk do very competitive MO and equivalences charts. They supply NGK

First time on web page for eaons. Champion N5 always fouled in all of the P4 (pre Westlake included) & P5 cars I have owned. I bought a set of Lodge (such a pretty shade of pink) from the late (& greatly missed ) Geoff Kent several years ago.
No Problem in my Mk3.
Maybe his son Barry who now advertises in P5 mag still has some in stock.

I too do not hold out much hope for Champion plugs.........as Phil says, they always seem to fail early. The only engine I even found ideally suited, was the BMC "A" series.
Resistor plugs also produce a hotter, shorter duration spark, due to the build up of resistance, instead of the slower, softer spark of non resistor types.
They should only be used in modern engines that use leaner mixtures which require it. Sometimes they are positively detrimental to engine performance in certain engines. As there is no advantage in using them in older engines, its not worth the extra cost.

It's news to me that a bog standard Champion N5 is a racing plug. this plug was widely used in the 50s, 60s,and 70s, on virtually all makes of car.
I personally think the owner was trying to justify selling a different type of plug. He doesn't appear to know his subject very well.

I tend to agree. The N5 is I believe just a "colder" plug. Only I can't see how the 3 litre can take an N5 or an N9Y as alternates as they each have a different heat range. The N9y has a protruding central electrode that stays hotter.
