I think the correct champion code is RN9YC
NGK is BPR6ES
RN11YCC i think is equivalent to BPR5ES which is colder, recommmended for LPG
others might confirm

Just fit standard plugs you don't need special plugs for lpg. Motor factors will use reg number for correct plugs. From memory the ngk bpr6es

My Blue 4.0 is running well with BPR6ES. My LPG not commissioned yet, but some people say cooler plug for LPG, but others say standard.
So, here's the thing, I've just replaced the plugs for the second time in ~8 years of ownership (I do less than ~6,000 miles a year.) The vehicle has done ~80,000 miles in 24 years.
The plugs in the engine when I bought it were RN11YCC's, and that's what I used to replace them.
Lately I was getting some dreadful throttle response (basically engine revs weren't increasing regardless of degree of throttle depression!
). I changed the plugs for NGK BPR6ES's.
No improvement (yet). (Car is basically unusable in its current state.)
I have cleaned the mass air thingy with the designated cleaner.
Next, I'm going to replace the lambda sensors.
Oh, and I get a camshaft sensor error (bank A)… So I imagine that's been screwing up the ignition cycle.
Anyway, if you're still with me, am I on the right track? Or can anyone suggest an alternative direction in which to head? (Apart from directly to the pub?)

Assuming it's a P38 like your first post, try throttle position sensor, coil or spark lead breakdown. Could also be a failing MAF.
Whatever diagnostics you're using are wrong, because cam sensor on P38 is only used for fine tuning the timing. Also there's only one cam, so "bank-a" is rubbish !!

Can't comment on the plugs, but I can tell you that running on LPG results in higher combustion chamber temperatures.
Make sure your cooling system is 100% !
Personally I wouldn't touch the stuff, based on previous experience with it in a RV8 .. but each to his own.

Agreed, but then the good 'ole 3.5L doesn't have a 94mm bore
