From what you are saying, then I should use the older plugs and not the newest dated plugs.
What happens if I decide to replace the coils at a later date after I have changed the new plugs. Will it still work or do I have to match the plugs with the coils.
Most likely going to buy the parts and have someone/garage install it for me.
It's winter here and I have no access to a heated garage.
I just want to make sure that I order the correct plugs.
I'm looking at autohausaz.com for plugs.
Another question for coils, my car is a 04/06 325i production and from the site they have 2 different set of coils to choose. Which one is the one I need from these 2 links? It would be greatly appreciated if you provide a link to other site about the coils that will fit my car.
..the latest plug you can use (with your current coils, and should work as well with updated coils) is NGK PLZFR6A11S.
Updated coils are: BOSCH 12137594937 $57.21
same as in a late model E90 328 (and the correct plug for them is NGK LZFR6AP11GS) The standard replacement coils are less expensive.
If Autohaus does not carry the right parts, try RMEuropean or PartsGeek.
