JWT Dual POP-Charger for 2013 370Z
 

What’s your opinion of the JWT (Jim Wolf Technology) Dual POP-Charger Intake System for the 370Z? It looks legit.

I’m looking at combining the JWT Dual POP's with the NISMO Cat Back. The gain could be over 10 HP to the rear overall.

I understand that the sound gain alone is amazing...

Most here agree that it's best to run a full CAI or drop in's. Gains may show when your on the dyno with the hood up, not so much when your engine compartment is as hot as an oven and your intake is sucking that up instead. The stock box pulls cool air from behind the front bumper. It really only shows it's limitation above 6500rpm. True cold air intakes only improve performance over the stock by larger and smoother intake piping, and a slightly better flowing air filter. I think after the ECU adjusts, the only thing your going to get from short rams is the sound.

Good Point on ECU
 

How sensitive is the ECU on the 370Z? Does it respond to micro changes in barometric / altitude, temp and humidity? I have detected some performance variances with weather changes. I also have a 1200ft elevation change daily on my way to and from work. It also seems to remap slightly if the AC is on...

I have the pop chargers on my '09. I installed them prior to getting my FI exhaust and just from that alone I noticed a crisper throttle response and my MPG increased a little bit as well. Now with both the pop chargers and the exhaust installed, the car performs even better and of course the sound is a huge improvement.
