Air Filter Study
Using OBDScan, I measured incoming air flow in gm/second according to the MAF reports to the PCM. I then graphed this versus engine RPM as I revved the car in park slowly toward 3000 rpm. The goal was to determine the gm/sec flow of each filter at 3000 rpm.
First I used my tried and true K&N panel filter, then ran the same test twice with a new Kool Blue panel filter of a similar design.
The graph below shows resulting gm/sec of flow on the up-slopes, marked "throttle opening"; the down slopes are while the throttle was closing and can be ignored.
My conclusion? Too confusing, so redesign the test. I think the data shows that the Kool Blue flowed more than the K&N on the upslopes. In the picture below I air-brushed out the confusing down-slopes which are not meaningful, and the red and purple lines Kool Blue lines are stronger than the blue K&N lines.
