Typo error.  "there is wear on the points"

As there is only a small amount of current switched at the points 
(primary spark) this means more energy goes to the spark plugs 
developing a bigger brighter spark there.

Also with less spark at the points there is LESS wear on the points 
and they last longer.

I can't report any improvement in performance using this system. but 
the emissions smell better (if that sounds right) as if all the fuel 
is being burnt. the box also has a switch to turn it back to normal 
ignition but more useful is the 3rd option on the switch which 
immobilizes the car by turning off the ignition, offering a small 
amount of security.
