Amazon.com: Customer Reviews: Pulstar be1i Iridium Pulse Spark Plug, Pack of 1 I know these are hardly 'professional' reviews but there is a lot of mixed opinions on them.

It's interesting that the people that gapped them correctly are happy with the results but the people that don't mention gapping them hate them, also, a genuine question, is the ecu adaptation a major part in this?

There seems to be a V2 that doesnt crack like the first ones, also there is one comment saying that a normal plug socket with a rubber insert shouldnt be used to tighten them. It's hard to see if the bad comments are from ignorant people that don't read the instructions or if the good comments are from people that just had duff plugs and improvements would be found from just new standard plugs?

Maybe we can all put £1 in a pot to pay for a set and an hour at bills to reach a genuine conclusion?
