Review on 2008-2020 Nissan/Infiniti K&N Cold Air Intake Kit: High Performance, Horsepower Boost: Designed for 370Z, G37 3.7L V6, 69-7078TS Compatible by Roberto Garrido

Looks great and sounds great. Gave my g37 a little more growl in the top end, not too different from the power, maybe a little faster. The system is easy to install, but some fasteners are in hard-to-reach places. Make sure you have plenty of little wrenches to stick in weird nooks and crannies. Brackets aside, this is a very easy system to understand and install. Be sure to reset the stock ECU after installation. The K&N instructions were more detailed and specific to my machine than any YouTube video I could find and I would definitely recommend following them. Came with all necessary parts and in perfect condition. Great eye candy.
