Cold air intake vs aftermarket airfilter

[jeritlejeune]

Need help, wanting to get an aftermarket cold air intake, but the reviews aren't great. Leaning towards a KN air filter for my 2015 Genesis Sedan 3.8. Any suggestions.

I would just buy the drop in panel filter. I assume that the gain in power will be similar with a possible edge in gains going to the cold air system since it does removes much of the restrictive factory resonator setup.

Most non-turbo engines do not pick up more than about 15hp on the high end(not common, but possible) with an air filter swap depending on how restrictive the factory air induction system is and how much the stock ECU can adjust for additional airflow. However, most realistic gains are about 1-5hp flywheel on smaller( 4 cylinder) non-turbo engines and about 10-15hp flywheel on larger non-turbo(V6 and V8) engines.

No one ever really dyno the Genesis sedan non-turbo engines enough to get a good read on how the ECU reacts to an performance air-filter for any real data to go by. One dyno pull here and there located online is not going to be very accurate since dyno calibrations and corrections varies by each dyno station used.

The best way is to just try them both and see how well your engine responds to each one based on your "butt" dyno. Just stick with the one you like the best on the road.

If you solely rely on this forum for answers good luck since you will get many varied replies based on individual opinions that may or may not apply to your car and driving conditions.

I would have to agree with @carguy75

I was on same boat for my 2009 3.8.

Just coming from dyno,
drop-in filter add about 3-4whp with secondary charcol filter removed from stock airbox.
then replaced oem intake pipe to smooth silicone hose, another +6whp were seen on same dyno.

Thanks for the responses and advice, it has been a little over a year and I have since installed an AEM cold air intake. I have noticed some improvement in acceleration not considerable. Although she does have a nice growl when I get on the accelerator.
