From two different 370's of mine: first is a 2010 comparing K&N vs paper filter only; second is a 2011 comparing K&N+Cobb tubes vs paper filter.
Eventually I will be trying a set of the pop chargers, which have nice built in velocity stacks -- HOWEVER, this will be in conjunction with custom made fiberglass airboxes. This will be a late summer project, so expect no updates before mid July.
There's nothing wrong with the Nismo exhaust as an upgrade from OEM IF you can pick it up on the cheap (say < $550 shipped; < $350 picked up) |
It looks like your data points are taken at different RPM levels between the 2 dyno charts , if this is so, it will give you a lot different readings if you measure your HP at 4000 rpm compared to 4200 rpm.
