Hello, vehicle: Alfa 156 2.5 V6 24V Built 98, 190ps Now that the weather is getting better and I have to get to my Alfa because the Lmm is in the bucket and I have to change it, I thought I can do him something good and buy him new spark plugs and oil My questions are: – Must it necessarily be the NGK Laser Platinum 3500 spark plugs that are also installed by Alfa or are there also good products from other manufacturers that can be used well? Ebay seen, Champion EON 1 which are considerably cheaper and are also offered for my vehicle. Is there any good and bad spark plugs at all or are spark plugs just spark plugs where everyone does their work equally well? -Because of the oil I am slightly unsure, in my manual there is what of 10W-40, 5W30 (synthetic) standard APISJ. On the Internet I have read the many 10W-60 of AGIP used and thus made good experiences. I looked around and to At least price the oil is good I have only thought about it because there is nothing from 10W-60 in my book, can I drive it without hesitation in my Alfa? -I think oil filter is oil filter and the main thing that is suitable for my vehicle, or should you also consider something? Thanks already for your answers M.f.g. Rouven
