we had a rep come and try these on our dyno, promised improved power etc. despite us saying a spark plug will make no difference.
we had a grasstrack class 5 car on the dyno at the time with a 1360cc TU engine in it, an ideal thing to test on. we said bring them down, if they make an improvement we will buy some.
we done a run with boring NGK spark plugs. done another run with the pulse plugs "guaranteed to make more power". and gave an identical test result to the boring £3.50 NGK items.
so the rep left with his plugs and tail firmly between his legs.
later that day he phoned us to say that we needed to reset the ecu to make a difference (wtf? lol) but when we told him the car on on carburettors and a distributor the conversation soon ended.
we have not heard anything more about these pulse plugs since.
