I don't see a problem with ngk's, i think you will find most people using these plugs, you just need to find which is the correct heat range for your car i'm sure someone will know.

thanks for your replies. do u now anything about the halo plugs?

i have heard about them, they are supost to save on fuel and increase on performance but i dont know anyone who is running them so i would take that as being the case.

I would go with the ngk's. thats what i am using

i previously had NGK IFR611A Iridum plugs, I now have denso IK20 Iridium which are superb, Will be sticking to denso.

Halo plugs instead of using a single bent electrode for the arc to spark across use three holding a ring. The idea is to increase the number of sparks across to light the fuel more effectively. Actually any effect would be marginal at best. Typically any well adjusted/gapped plug will light the fuel effectively and give you an optimum burn and hence performance/economy.

The main advantage of iridiums is they hold the correct gap for longer and need less in the way of adjustment. In of themselves they don't give a direct performance advantage, they just need less maintenance to hold onto the natural performance.

NGK's or Denso as mentioned above are perfectly fine
