Review on 🚀 K&N Cold Air Intake Kit: High Performance, 50-State Legal: Compatible with 2001-2004 Nissan Frontier, Xterra 3.3L V6, Part Number 57-6010 for Increased Horsepower by Daniel Delgado

I needed this to transfer smog on my 2004 Nissan Frontier 4x4 CC V6 Super Charged. The previous owner fitted another one and the hated government agency CARB has ruled that it cannot be used. Inlet 57-6010 comes to the rescue. The components are good, but it takes time to get everything right. Basic hand tools, two hours and a cold beer are all you really need. I haven't noticed any increase in performance, having previously had a CAI from another company, but it seems to do the job just as well, if not better. Also, the instructions were good. They're easy to screw up, so points for that. All in all, thumbs up for K&N!
