above a stock air filter

and the testing also shows that the K & N air filters do not actually "filter" the incoming air as well as stock OEM air filters

as you know the MAF sensor only samples a small percentage of the entire air flow and if the flow at the sample area is disturbed or re routed by tampering with the air box assembly then ....

your POS cone air filter very likely is not directing air flow to the MAF sensor correctly (as designed) and because of that the MAF is under reporting
this results in changes in the way the ECM assigns values to many thing
including spark timing and injector pulse width

you can test my theory by providing long term fuel trim with calculated load and MAF flow values and ign timing values at 55 mph on the same stretch of highway with your new POS filter and the original OEM filter

any generic OBD2 scan tool that can show real time live data can perform this task.

until then
this should be relegated to the UNICORN thread as it is bogus .
imho
