MAF Screens
i read on a website that taking out the screens on the MAF sensor would increase airflow and give about 10 HP and about 12 lbs torque. anyone know if this is true/safe? MAF sensors arent exactly cheap and I dont want to mess with it without knowing.....anythoughts?

Leave it be. If your still convinced descreening will be an improvement, only remove the rear screen. This way the front screen will still protect the MAF wire.

The air fiiter's job is to protect the MAF wiring.
On an L98, it frees up about 5hp or so, so I would do it. You will not notice the difference however, and I would NOT recommend touching the heat sink fins inside.

I've got four sets of MAF screens laying in the top of my toolbox, if that lets you know how I feel about them. Get a sharp knife and just cut around the seam until it falls off. No bigee.

Go ahead if you want...personally mine will stay, they were installed for a purpose...something to do with the air flow, maybe the general just wanted to spend a few more bucks on something worthless. And I'd sure like to see a before and after dyno proving a 5-10 hp gain

here is something to think about i have both screens removed and heat sinks taken out of mine allways had
but i did a test a couple of years ago i run a k&n filter with a cold air setup i decided to remove the k&n filter and replace it with a filter i made up which consisted of just a plain piece of screen sandwiched in place of the filter and actually lost et and mph i went back and forth on two seperate days and confirmed the k&n filter in place was faster and quicker than virtually nothing at all
the only thing i can come up with is what k&n claims it actually staghtens the air flow collum is true

Go to pepboys or a local auto parts store and buy some MAF cleaner first. hmm.. not sure if it would prevent it from starting though.
