[Udi Siag 0]

hi mates,

When u go to NGK.com u can choose ur car model and find out wich spark plug is going to fit in ur engine.

I know that the platinum means more life, but i don't care about lifetime.

I care more about better performance.

Now my question is , does it make any different with the performance when choosing betwen these spark plugs??

V-power -BKR5E

Imho plugs don't make any difference unless your running forced induction, so just standard normal plugs will be fine. I also think long life engine consumables that are over priced are a waste of money.
