Welcome Kymco Owners!
Hi,isnt there any other type plug we can use then ngk c7hsa?I see same plug on ebay.uk for £1.00 and here (Norway) cost about £7.50 LATERS
The NGK 4629 is a standard copper plug and a cross reference to the C7HSA and I have been using it with no issues. Only like a couple of buck at my local autopart store
