Bongo Fury

Yes, interesting Haydn but might mainly be interesting marketing. Standard J5 V6 petrol NGK's seem absolutely fine in ours, although I can't deny that an improvement in LPG consumption if really achievable by the BRISK plugs, without unwanted side effects, would be welcome. However, our emissions are infinitesimal now - doesn't that suggest efficient combustion already? Are you going to try them? Keep us posted please, if you do.

Did you change your standard plugs today, and with what result? If it didn't clear the misfiring, I would be inclined to find the cause of that before trying a new type of plug altogether, to avoid introducing too many variables at once - as it says, you have to retune the LPG system to use them.

EDIT: Correction - I've got standard J5 V6 petrol Denso plugs fited, ex Bongo Shop - same applies, they seem absolutely fine. Previously had NGKs.

The power of advertising .!!

There have been many 'unique' sparkies over the years .. who can remember 'Spitfire' (not Splitfire) plugs..??

Instead of side electrode(s) Spitfire had a disc with holes in .. the centre electrode causing H/T lecky to arc over the holes in the disc .. I had some in the 1960's ... rubbish ..!!

I reckon with things like plugs .. oil .. tyres etc: many people have there own preferences ... I like Bosch and in Particular NGK

My Emmy as always sailed through the emissions on LPG and Petrol

Ive been running on Bosch super 4's (fr78x) for nearly 3 years on LPG and the plugs have shown no sign of deteriation at all Ive now covered over 50,000km with these (changed annually with service) so i think that speaks for itself Try them for yourself, £3.49 each on ebay.
