Default Screenless maf is this ok?

Does a screenless maf improve airflow or does it hinder the engine?

Uh oh, the flood gates are now open. I don't know, but I did mine anyway. I didn't notice any difference really. I didn't have any of the problems that some poeple claim to have with their A4's.

I was kinda wondering more along the lines of , is it "safe" to run a screenless maf, I don't want to sacrifice safety for power and if screenless is not safe for a manual then I wont do it.

I put 1000's of miles on my screenless MAF with no problems on an M6 car.

I got into this pretty heavy too. Although the car will run and is safe, GM spent a ton of time making the PCM program work with the MAF screen. They also did the same for the Z06 screenless MAF. Point being is you can do it, but a tuner will need to 'remap' to accomodate more airflow. Read more at LS1Tuning.com about it. Also Mike, from what I undertand, Brian at JD's is capable of doing it for you ( retuning for a different MAF ).

My $.02.

I've been running with screens on all my Gen III vehicles (5 of them) for 5 years now. No problems. Just make sure your filter/lid seals properly.

It does increase airflow. I saw flow bench #'s on a site.

I have NEVER heard one case of a descreened maf causing problems of any kind. Ported maf yes. Descreened no. Its a good mod
