For many years I use the Bosch WR78 Super 4 spark plugs in my E-Type S2 and my Healey 3000.
Both engines are mildly tuned and run just fine with the 4 electrode Bosch.
Kind regards
Frank

Re: Lower steering column
On my 69 S2 FHC with manual steering the total length is 87.2 cm
Not sure if this used one from SC Parts would fit?

Re: 4.2 3x45 Webber’s running 12 deg advance?
Hi all, Did some more testing on my setup. To compare each test drive I installed a small endoscope camera on carb 1 and made small markings on the outside of carb 2 when each of the progression holes is opened.
