New Plugs

I'm getting my car protuned tomorrow and is it really worth the 140 sum that its going to take to put them in? I am going to upgrade injectors and pump down the road and it would be alot easier to get them in then. Do they make a big difference? They are the step colder iridums. Thanks

 

i would get a step colder coppers....

 

i already have the iridiums. Are they going to make a huge difference or should i wait?

 

IIRC those don't exist, at least for the STI(unless any of the other copper plug people found some). What plug is going to depend on your setup. I would highly recommend replacing them before tuning.

 

thats what i thought as well.

 

ok does anyone know where to find the accesport manager update on cobbs website? I am trying to update the new firmware and i need to do that first. Can anyone give me a step by step on what i need to do to get this ready? i've never used on before. Thanks
