Hi,
I have a 2011 Fiat Punto Evo Sporting 1.4 Turbo Multiair(135hp). In the owners manual it says I should use NGK IKR9F8 spark plugs however on NGK website it says that NGK IKR9J8 spark plugs fit my engine. I heard from somewhere (can't remember where) that the IKR9F8 model was replaced or something. Having said all this, both models are still available and so which one should I use for my car?
Thanks
