Una - I also had 2 small screws left after my install...I have no idea what they are for.

 

Sorry to hear you are skeptical, Karlfungus. JWT makes a fine product (with the exception of vague instructions imho) and has a dyno chart for the Popcharger on their website. I did my homework on this one, and there are definitely performance gains over stock, especially when combined with the Z-tube.

Check out some older posts, as I believe some people reported decreased horsepower/performance from the drop in K&N.

 

i agree, the JWT Popcharger is actually a dyno proven product that improves power. look at the praises on 350z.com and u'll run into dynos there as well.

 

Anyone have picks of the new heat box for the Pop charger, the one that looks like the Stillen?

03 - Black - Premium - Wood - Aero w/ Spoiler
Z Tube - Stillen AirBox

 

Ok, I guess I forgot to include the MAFS adapter bolts in my list.
Instead of having 2 bolts for the center air scoop bracket, I only had one.
In its place are two small screws.


Here are said screws, next to an OEM MAFS bolt.

Hmm, I got 3 bolts and 2 washers in a bag, 4 bolts other attached to the airbox itself. No small screws here.
