Ibought a turbocharged 1.8l protege and wanna do a tune up. I was looking up the bosch iridium fusions plugs. Has anyone tried or heard about them? ShouldI just stick to ngk, if so howwould the gap setting need to be adjusted for the turbo? This is my first turbo car so I'm just a beginner. Any help would be appreciated.

 

I don't have direct experience w/Bosch iridium fusions plugs, but have had good luck w/both Bosch and NGK plugs, depending on the application. Bosch makes good products (generally speaking) and so does NGK (generally speaking.)
I have also had good luck w/(of all things) Motorcraft plugs, but again depending on application.
Try 'em. what have you got to lose, except perhaps some overall miles?
