Tbh i'm not sure that the Gen 2 are that good . It still has the top open to the heat , it would be better if it was fully enclosed .
Heres a bit of a prototype i've made using a k+n cone filter and a homemade fully enclosed heat shield . It uses both the oe cold air feeds , has a nice throaty roar when you floor it and pulls just as good as the panel filter , definitely no loss of power at all speeds , even when i've been in slow moving traffic.
It needs another end cap making for 90 elbow end then it will be fully enclosed , haven't had time yet .Just a few pics so you get the idea .
