searched all over to find a solution but couldnd find one, I have a tear in the intake coupler connecting the ztube to the filter,
i have a stillen z tube and jwt popchager. Where can i find a replacement for this. I called infiniti and they told me i had to buy the whole thing for 190$.

 

Try Nissan part 16577-5y700
It's just the 3" flex tube. Listed as a maxima part. Worked for my 04g35x
