Can the factory mounts handle boost ok or should they be filled or replaced? Mine are almost 16 years old and they have never given me problems but I'm afraid they might be too old to handle the shock that FI would put on the engine. What do you guys recommend?

 

I would say it would be a good idea to swap them and maybe add a bit of 3m if you don't want to go with a harder mounting option. If your tib is a manual you should do it anyway. The motor being still = better shifting even with N/a power levels.

 

I use red poly's on bottoms, But replaced the stock sides 2 years ago brand new(expensive),but I did notice a difference ..FI does work them hard.

Go solid.
