Iain T Posted April 2, 2021 Report Share Posted April 2, 2021 I think you fit all the multi tip plugs as is. I certainly am not going to fiddle with my W78's, the tips of the electrodes are curved! Iain Link to comment Share on other sites More sharing options...

I now run on OEM champions. These have a coating on the insulation in the interior of the plug and don't get contaminated Aidan Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 2, 2021 Report Share Posted April 2, 2021 wish i had driven mine enough last year to warrant gapping the plugs Pete 1 Link to comment Share on other sites More sharing options...

It will be interesting to see how this works out, it's certainly worth a try. Derek. Don't expect a major transformation, the improvements are subtle, but are definitely real. Then there's the advantage that M/E plugs are maintenance-free for tens of thousands of miles. No need to re-gap, and very unlikely to foul, so no cleaning either. M/E plugs actually work out cheaper in the long run. I wouldn't go back to single electrode plugs. Nigel Link to comment Share on other sites More sharing options...
DerekS Posted April 17, 2021 Report Share Posted April 17, 2021 Some feedback regarding this thread... I've finally got round to fitting a set of W7DTC's and have to say there IS a noticeable all-round improvement. First off, I was able to push the choke in quicker after setting off, no engine "hunting"; the car is definitely smoother, it pulls better and tickover is smoother too. Well worth doing and thankyou all once again for the advice. The other point to make is about "The Green Spark Plug Company ", absolutely brilliant to deal with, I wouldn't hesitate to recommend them, outstanding service! 4 Link to comment Share on other sites More sharing options...
SpitFire6 Posted March 19, 2022 Report Share Posted March 19, 2022 Hi, Spark plug, Worst one. BUR6ET. 10,000 miles. Changed to Y single type with 1.1mm gap. Addition of castor oil & crap DIY PCV system caused this I guess as compression pressures OK. Link to comment Share on other sites More sharing options...

SpitFire6 Posted March 20, 2022 Report Share Posted March 20, 2022 My DIY Positive Crankcase Ventilation system sucked a lot of oil into inlet manifold. Apparent when coming off the motorway. I add 33mL of Castor oil to the fuel tank occasionally to make people believe I'm running R40 engine oil.🤣 But, over half the plugs looked old but fine. What is it? Hope its not an aluminium compound? Link to comment Share on other sites More sharing options...
