The IM sure will help with out boost. It has individual velocity stacks for each port. Larger reservoir, light weight, larger internal bore on the flange... Not to mention it's just a much smoother surface than the factory cast piece, inside and out. You may not see huge numbers, but it will help. It should also yield a few more MPG.Looks like parts to only benefit a boosted platform... i doubt that the IM will do much though? shatner chime in perhaps?
