I'll try it with it off and see, but don't see how it would make much difference, the temps really didn't fluctuate much but .1-.3 difference which isn't much
@@TboneSRT If you tested one after another and you have air recirculation on then it's pulling in cooler and cooler air as it's cooling down the interior of the car and recycling that cooler air. A proper test for 'Delta T' in A/C systems in this case requires a reference source temperature (eg. outdoor air). So, air recirculation OFF, then compare outdoor air temp (preferably at the air intake point usually on the cowl intake vent) for each filter and record the difference (Delta T).
@dancox3251 I guess if you want to get real precise, that would be the way to do it. But there's no disputing an improvement over the oem filter. It's more restrictive i.e less cfm which means the blower motor is pushing less air through the filter. It's like having a clogged air filter vs a clean one, a clean one will move more air than a clogged one.
@@TboneSRT I would agree if the test results made sense - but they don't with the no filter (least restrictive option) performing worse than the more restrictive K&N filter option.
Turn off air recirculation and try again. Naturally temps drop because the intake temps are dropping.

It be better if I know where cabin air filter was to replace it. Lol
Do they have these for the changers?
yes they do- www.knfilters.com/vf2027-cabin-air-filter
@@TboneSRT ok thanks for link👍🏼
