MK3 Posted March 31, 2013 Share Posted March 31, 2013 Standard MK3 Spitfire due a new set of Spark Plugs. Paddocks have 3 offerings for the MK3 1300 engine : NGK Dual Copper RN9Y, Motorcraft Autolite RN9YT triple electrode and a Champion N9YCI would normally go with the old fashioned N9YC but has anyone tried the triple electrode or the NGK and thinks its a better plug ?

Clive Posted March 31, 2013 Share Posted March 31, 2013 NGK BP5es or BP6es for me....Not had an issue with any in the last 22 years. Champion used to cause a few issues, but things may have changed. Quote Link to comment Share on other sites More sharing options...

mjwman Posted March 31, 2013 Share Posted March 31, 2013 DO NOT buy any plug with an R in it. These are resistor plugs and our systems are not up to it nor are they needed..NGK BP5ES or BP6ES are ideal. Quote Link to comment Share on other sites More sharing options...

ferny Posted March 31, 2013 Share Posted March 31, 2013 Lower number, hotter plug. BP5ES goes into an Acclaim... (whistle) Quote Link to comment Share on other sites More sharing options...
Clive Posted March 31, 2013 Share Posted March 31, 2013 Agreed colin, get 5's, though I am none to sure just a change of plugs will solve that particular issue! Quote Link to comment Share on other sites More sharing options...
thescrapman Posted March 31, 2013 Share Posted March 31, 2013 Think I already have 5's... :-( Quote Link to comment Share on other sites More sharing options...
