Just finishing a tune up and could do with new plugs......are you all still happy with the Champion N9YC 's ?
Standard car, using Shell V Power petrol......and running very well, so no reason to change type of plugs unless there is something better these days....

I find the Champions OK and work fine, but the NGK equivalents seem to last a little longer (BP6ES from memory) but nothing in it really

Re: Sparking Plugs. 1970 BGT
I tried Bosch 78R super 4s in one of my MGBs a few years back and found them well suited and I have them fitted to my current 74GT. Maybe I have been suckered by the marketing claims of the copper core and the four separate side electrodes making them more efficient but I must say that my GT is running very smoothly and starting and economy is markedly better.
Give them a try, plugs are cheap and so quick to fit, what's to lose?

David, I've got them in my Stage 2 engine where they've been for the while with no problems.

Re: Sparking Plugs. 1970 BGT
Whilst at Stoneleigh yesterday, I bumped into some 'old' T-Type racing friends, who were looking at NGK plugs on one of the stands. The ensuing conversation was around the lack of a coating on the insulator of the centre electrodes of modern NGK plugs. This was provided on NGKs of old but the advent of closely controlled mixture and spark with modern engines and electronics means this is no longer needed. But when these plugs are fitted to older engines (like the XPAG, A-series and B-series) the plugs keep fouling up. So NGK might not be the plug of choice anymore.
Can anyone throw more light on this?

Hi Peter, NGK plugs still work as always in my BGT, so I haven't noticed any differences of late. The engine is only mildly tuned though, so may not be very sensitive to plug make and heat range.
For everyone - don't buy your plugs from that well known high street retailer - try this company - http://www.gsparkplug.com/
NGK BP6ES are £1.34 each, Champion RN9YC are £1.99 each. As usual - I have no connection with this company other than being a very satisfied customer!!
