I have a boat with a 1989 gm 5.7 liter. will these fit? i can not look it up - sorry for the repetitive question.

I don’t know I put them in a 4.6 ford motor

Do these fit a 2004 deville ?

I'm not sure. Do look them up under your car's make, engine type, year, and model number, just to make sure.
