Hello All,

So I've been cleaning out the closet and tool boxes and I found spark plugs that I purchased previously for my 05 Grand Prix GT. The plugs are NGK TR55GP (Stock number 3403).

I no longer have the car as I've gone to an 05 Grand Prix GXP. Would these plugs be ok for the car? Or would you recommend I sell them and use something more suited for the GXP?

Thanks
