We all have our preferences and my favourite are Unipart GSP 531 They seem to suit the engine really well

My P5B with SD1 V8 engine runs good on champion n9ycc but only on petrol. For LPG they are not good! Now I have NGK bpr5es and it runs very good on both petrol and LPG.

I use NGK BP5HS (BP6HS can also be used for a colder plug option) or Bosch W8BC
