I hate to say this but I call BS. I did the same testing and gained 2-3 peak whp and same wtq. This was 3 back to back with stock filters, 3 without filters, 3 with k and n. The biggest bump was with no filters where I got about 5 whp but same 2-3 wtq as k and n. Also, the filter he uses in the video is a fram and not genuine infiniti.
Could you post your dyno graph? I would like to compare shape of the HP & torque lines.
Is your G37 have RWD or AWD and auto or manual tranny?

Just looked at your dyno and your dyno operator made a mistake.
Your correction factor is shown as "SAE 1.00", BUT it can't be if the temperature is 91.7, 30.18 pressure with a humidity of 38%. The SAE correction factor is 1.00 when temp is 77 degF, pressure is 29.234 inHg and humidity is 0%.
Your results are at least 2-3% higher than graphed. (Assuming the dyno operator didn't screw with anything else like over tightening a strap)
You might want to get your car dynoed again at a different shop. I suspect you will be happy with the result.

Oh for certain. I won't be going back there ever again. Either way though, no changes were made except the removal of the filters and the gains were negligible. In fact, after back to back pulls, the numbers with filters and without started to be exactly the same. This dyno I also showed no gains at all with r2c intakes installed.

Our cars respond well to K&N filters, Silicon Intakes and a resealing of the area where the intake meets the radiator support.
