I'm thinking of trying NGK Platinums on my 2.4 Cavalier (n/a, stock). The part number for NGK is TR55GP they are G-Power Platinums. Has anyone tried/uses these on their 2.4? Are these worth a try? The delcos are gonna cost me 50$ locally but i can get them for 25-30$ from the states., thats why i'm asking. The NGK's cost 15$ for all 4.
