Security was unusually tight going through the checkpoint yesterday. Malaysian cars getting a good going over, more so if the occupants were younger looking males. I was given a once over, albeit briefly, as perhaps I don't fit the profile but nevertheless, you could see and feel a high degree of tension from the border guys and gals. They're normally pretty affable and chatty but yesterday, it was all business.
Anyway, away from that I can say without a doubt that the NGK plugs have made a world of difference and can validate everything written here about how they function compared to the horrible Bosch ones.
