Are thoes bosch 4 tip sparkies any good and or safe for a cobalt ss 2.4?

 

Just so you know, I am an old school VW mechanic. By that I mean, I'm pretty plain jane when it comes to basic engine accesories. I would go with the plug recommended in your owners manual. It is specifically designed for your engine application. Also, most four tip plugs are platinum and where this can get you into trouble is high compression conditions. Platinum plugs run hotter and you can risk premature detonation. Just some food for though.

 

also we dont have wires
