Comparison of the resistance value of the spring of the direct ignition
Photo1 : Unused Resistance value: 2.4 Ω
Photo2 : It is 32,000km from a new car. Use of about 3 years Resistance
value: 8.4 Ω
Photo3 : 24 gilding springs Resistance value: 1.3 Ω

The spring in the tip cap repeats dew condensation and drying.
The stock spring does not use materials resisting corrosion. It seems that
the surface is oxidized and forms an oxidation film, and contact resistance
I used SUS304 which resisted corrosion for a spring and realized half resistance
value of the stock spring because 24 gilt it after, furthermore, having
given nickel plating.
It become about 6.5 times high resistance when I compare the stock spring
which used for 3 years with 24 gilding springs.
