afe magnum force CAI with dry filter for 2016 F150 3.5L EB engine: Any good?
I'm seriously considering installing a Afe Magnum Force CAI Stage-2 XP intake system with dual Pro Dry air filters. Any thoughts on this product? Ya or Na?
I will also install their billet throttle body spacers and a Flow Master outlaw cat back exhaust system.
Will I need a tuner or the factory computer will compensate for these equipment

Ok, to start with let's talk about the spacer......
Spacers were originally created back in the 50's to create longer ports to increase velocity in carbed engines....and it was very successful and used throughout the decades up through the 80's when carburetor type fuel injection was then introduced. It was then re-introduced and found to have very limited performance increase...about 1 hp IIRR...basically negligible. The primary purpose was by increasing the intake length, this would increase the fuel/air mixing leading to better atomization of the fuel.
With modern fuel injection, this design element has completely disappeared......as the throttle body merely acts as an air flow adjustment meter...it does not mix fuel nor does any fuel pass through it.......it is all downstream just above the cylinder heads where the fuel injectors are located....those that have direct fuel injection, the injectors place the fuel directly into the cylinders. The spacer has absolutely no effect on the performance of a modern fuel injection system (just a fact of physics and laws of scientific tests conducted at ISO certified facilities).
Ok, let's just take a look at basic physics.....and a completely separate simple engine.....Fords 5.4 V8 in the F150.....
The 5.4 V8 for example if close to stock can only suck in a maximum of 480 cfm and the a flat panel filter will flow 500 cfm, ....so how can just a spacer, or a throttle body or a CAI force more air into an engine that is already injesting everything it can? It can't plan & simple- basic laws of physics without a forced induction system.
To calculate the max CFM of any engine, the formula is..
CID x max usable rpm divided by 3456 x volumetric efficiency (because the EB is turbo'd, your ve would be based upon max boost which IIRR is 16 psi...... atmospheric psi is 14.7 so you can do the math)
If you figure it all out, the oem filter will flow everything your engine can suck in + about 10%. Testand Corporation conducted an ISO standards test on automotive air filters which can be viewed at this link: http://www.dieselbombers.com/chevrol...r-testing.html, and you'll be a bit surprised at the amount of dirt that many of the aftermarket filters let through...not good on the pistons or turbos.
The catback...what ever sounds good to your ears.
