that coil only use by old cars b4 electronic ignition was used.
todays cars doesnt have it coz it is built in the distrubutor or using electronic device to create high voltage spark.
i think u cant use it on vtec engine coz its a "modern" engine.
Why you want it ?
Ignition coil is just supplying high voltage electricity to the distributor then to the spark plug cables.
Its not a performance part :) wont do any improvements
Consider this, a front wheel driven Volvo with 306hp, 400Nm. Who knew, that a Swedish marque known for building safe cars would put that kind of power on the front wheels, and is that even realistic? We’ll come to that later.
