ok guys, I got all confused, please help out...
sorry I didn't go through the million post but I need to know exactly what plugs I should get.
I have a MSP and I've search on the
www.clubplug.net and it shows me I need to use Iridium IX ZFR6FIX-11 (18-4750-0). which I'd really brought from the local parts store (they told me that is the right one)
now when I search the posts, everyone is saying they will replace it with ZFR7F-11. I know it is a step colder then the ones I got, but which one should I go with? the local shop say there is no such thing as ZFR7F-11 so they won't be able to order it for me.
If the ZFR7F-11 is the one I should get, where can I buy them for best price? what is the part number? and would the damn cold weather in Canada affect the performance of the car if I use the 7 series plugs? and what gap should I be using?
thanks guys.
