Removing MAF screen on 4.6

[Rey]

For those of us who are looking always for more power, better gas mileage and don't mind a tiny bit more intake noise at open throttle, consider removing the MAF screen.

This is an old trick that I first learned about dealing with GM's LS motors. GM owners often remove the screen picking up about 3 rwhp. In GM autos the screen is glued in place and is usually destroyed on removal. The screen obstructs roughly 10% of the MAF on GM applications. The Genesis screen is held in place by light friction, which means not only is it easily removed, but also it can be easily restored.

The stated purpose of the MAF screen is to smooth airflow past the wires on the MAF so as not to confuse the signals. GM has completely removed this screen on Corvettes, and perhaps other models.

The 5.0 Genesis does not use a MAF

I believe this was already proposed by j0nblayz in this thread:

Unfortunately for you, j0nblayz patented the idea, and therefore you will be assessed a $1 Billion fine for patent infringement.

^^ Damn!!! An apple joke!! That was FANTASTIC. I cannot believe you snuk that in there hahaha

EDIT: I know what the OP is talking about and I am pretty sure the thread you linked is not about that.

In most OBD2 cars, there is actually a screen (resembling a very fine window screen) placed ON the MAF adapter to smooth out the air entering the MAF. He is talking about that screen, I believe.

lol @ mark

hopefully he's talking about the secondary filter. if i remember correctly, the screen on the intake piping is built into the pipe, so you would have to dremel it out.
