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 Joshua Follansbee

Installation was easy once you know what you are doing. The tubes are machine welded and I had loose and protruding metal in my O2 sensor port. Be sure to check out this area! Of course, no one wants shards of metal getting into the throttle body. It took me about 20 minutes to make sure all the fragments and burrs didn't go into the tube. After that, the installation was very easy. However, the recommended hose length is too long, so you may need to change it for a better fit. Overall I'm happy with the product but was initially disappointed with the lack of quality in the intake pipes, particularly where the oxygen sensor port was welded on.
