I found this very helpful on my 12 Nissan Frontier when trailering my boat...there is a definite HP increase at higher RPM's when climbing hills.

I drive a 2002 Nissan Frontier with a supercharged 3.3 v6 I installed a 3 body lift and 5 suspension lift added a set of general grabber true 35 12.5 on 17 inch wheels Completely rebuilt the transmission.  I needed to replace my stock intake air cleaner which is very intricate and would no longer line up with the 3 body lift this intake kit not only fits perfectly with minimal trimming and re drilling a few holes.. it went in very easy even with the mods made to my truck.  I am extremely happy with the performance increase feels drives like it did before I put the oversized tires on it.

So I own a 2004 Frontier SVE, removed the O.E filter box with a KN PANEL FILTER and INSTALLED a 57-6010 FIPK. What a ride.  Furook, thats the trucks name, yeah I know - dont ask, had lots of go with just the supercharger, now its got gobs of power and torque.  So, then I buy the wife a Nissan Xtrail 2.5l dohc.  Washed the panel filter from Furook and installed it into the Xtrail as applications are same filter. Performance fuel econ, unless I throttle hard on the SC are great.

I install the KN oil filters too, top of the line product, the company I am a part of sells lots of these awesome filters.
