It seems nissan snuck up on us with a new performance part and it looks promising. Even though Rtune products don't fall under warranty. R tune R&D is excellent and custom pieces like body braces, brake pads and and sway bars are top quality parts. The picing is competitive with the gen 3 and looks like it has better positioning. I can't tell if the front bumper has to be removed or not cuz it doesn't say. But if you can change the filters without removing the bumper and risking the integrity of your front bumper??? It will definately be worth it.
