A Ford MasterTech made this videowhich talks directly about the aftermarket CAI’s.
Now please forgive, but a bit of the "Dutch Uncle" talking now..... you already have a CAI......
Ok, let's just take a look at basic physics.....
The2013 Mustang 5.0 V8, for example if close to stock (assuming 6,800 max rpm& 90% volumetric efficiency- note that is race car spec and likely higherthan reality) can only suck in a maximum of 535 CFM, and the OEM flat panel filter ( 12.375” x 9.675”) will flow 718cfm,
....so how can just a CAI force more air into an engine thatis already injesting everything it can? It can't plan & simple- basic lawsof physics without a forced induction system.
Testand Corporation conducted an ISO standards test onautomotive air filters which can be viewed at this link: Duramax Air FilterTesting * - Diesel Bombers.
“After only 24 minutes the K&N had accumulated 221gms ofdirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3times faster, passed 18 times more dirt and captured 37% less dirt.”
If you look at the flow data, WIX HP filters flow 98+% ofK&N and have a much smoother flow post filter plus excellent filtering, fora fraction of the price! on an OEM replacement unit.
I know...science and real data by an ISO certified testfacility.
The formula which is used by every air filter manufacturerin the world to determine the CFM for flat panel filters is...
Flat Panel CM= Length x Width x 6
So, take you relatively stock engine, calc the max CFM basedupon mfg specs; calc the max CFM the oem filter will flow....now show me howsticking a filter that will flow 900 CFM will increase the performance of anengine that can only suck in a max of 535 cfm? it can't
bad math, no science...all PR
