Quick Advice: JWT popcharger w/ztube or Motordyne 5/16 Plenum Spacer

[hiryux]

Basically like the title says I need some advice in deciding what is the better choice to go with as my first performance upgrade for my 04 G35 Coupe 6MT. I've searched around the forums and it seems to be a bit of a gray area cause it's split between the two. I kinda want to get an idea of people's personal or similar experience with these products and can tell me if they see any performance difference. I would like to get both but can't afford buying them both at the same time and just going to pick up one in the mean time.

My air filter is a little dirty but is not really bad so I'm leaning towards the JWT popcharger with the z-tube but I've heard the Motordyne 5/16 ISO thermal spacer gives an overall performance boost and is a good first choice upgrade.

What do you guys think I should go with first? Thanks in advance.

Go with the JWT/Ztube first... then spacer... then exhaust.

If you have an AT, I also hear that Grounding wires are a must have for smoother shifting and a better throttle response!



*edit* nevermind, just saw you had the MT... the wires are still a great mod but apparently not as noticeable on a 6MT.
