View Full Version : MAF sensor

If I remove the screen will it throw a code? I was told it would breath better without it...
Is this bad juju?

it wont throw codes. i wouldnt recommend removing it if its your daily driver. ive seen some crap passing through the might be the lid fitment but again i wouldnt risk it. plus you wont feel a thing.

OP, if you already had this thread started here why would you start the same thread in another section?

The screen is in place for a reason. Its purpose is to straighten airflow across the sensor to provide the pcm with a more accurate air flow reading, also can be a last resort for catching any debris. I say keep it!

dont remove your screen, for the .07rwhp you might get, its not worth the small leaves/bird feathers/grass/dirt in general ive found up against mine, that would damage the rest of the MAF and probably not be great for the engine ether, and i dont have a lid, i have the volant set up

If you are looking for better performance from a MAF sensor standpoint, I would suggest upgrading to either the SLP 85mm MAF (no tune required) or the C5 Z06 85mm MAF (will need tuning).

The Z06 MAF has no screen, I guess the Corvette guys are
OK with just making sure their air filter is properly seated
and don't seem to cry much about debris.

There's way more than 0.07HP hiding behind the "screen".
It induces a lot of pressure drop at high flows. A stock
motor with stock shiftpoints and restrictive exhaust may
not show you much. But by my measurements, at less
than motor flow rates, the screened MAF is as much pressure
drop as the stock lid while the descreened MAF has too
little to measure (<1/16" H2O). Everybody changes out the
stock lid.

Do not buy "MAF ends". Buy a junk MAF, and pop the screen
out of that, and swap over. Then you can go back if you
don't like it.

Of course this has all been said time and again. Search is
your friend, you don't have to sit and wait for people to
repeat old news to you.
