the screen in the mass air flow sensor

What happens if you remove it??? I have an 04 GTO. Will things start to mess up??

**BIG D's SS** · 05-15-2006, 12:50 PM

People have different views on it. I removed mine and there for a while mine would set a code cause it would let oil from the K&N filter would get on the little wires. I don't know if it is worth removing it or not.

mine started to shift odd

**suaveamente** · 05-15-2006, 01:26 PM

odd like how?

**redz284u** · 05-15-2006, 01:28 PM

hesitant early shift...........like it would try to shift up to early

keep in mind mine is a A4

I've taken it out on both my SS's. I cleaned up the MAF wires(very carefully) and never had problems. I also have a K&N, and lid on both cars too. I have also done the free air mod and egr mod to both cars as well. No problems.

The have done the same as Huskerz1 with my one SS and I have had no problems.

it frees up a few extra horses from what ive read, and all its supposed to do is line up the air so it flows straight into the intake manifold. Its only required for anything other than straight intake piping into the engine. I havent taken mine out yet, but i plan on it this weekend.

it aint worth putting your engine in danger for like 3 hp come on now

I took out my mass air screens and did the free air mod and my car loves it and I have no problems. IF your getting oil off your k&n filter theres to much oil on the filter.

In danger from what? I guess if your a4 shifts early and throws codes then worst case scenario is your get another to put back on. I have never heard of the shift early bit. I have however heard of the engine codes from oil getting on MAF and sensors. Just clean the MAF gently. You should do that periodically anyway. Especially if you have a K&N. Even with the screen in there the MAF will eventually get filthy anyway.

What do you clean your mass air with.

I used alcohol, q tips, cotton balls. Also cleaned my throttle body too. On mt SS vert, which I bought used with 70k on it, The MAF and TB had never been cleaned. The MAF was dirty as hell. I pulled the screen out and cleaned it up.

huskerz1 did you do all the free mods to your cars.I have three of the five done so far but i'm debating on the t/b bypass and poting the t/b because I just saw a vr product that smooths out the air going into the t/b wicth is what you do when you p/p the t/b and it's $50 vs $100 if you don't do it your self

I find bugs and all kinds of crap stuck on my MAF screen all the time. The 2 hp you'll gain from removing it, isn't worth all that junk getting sucked into the engine IMO. Guess I'm just not that hardcore lol!

I have not done the throttle body bypass mod or the drill mod. I don't have any reason other than I just haven't done them yet.

BUGS! in your MAF screen? Maybe you have a fittment issues a little further up. Like I said, I just did it to the vert I bought with 70k on it. There were no bugs or juice on the screen. Surely after 70k you'd think if that was going to happen it would have. The MAF was just dirty that's all.

This mainly happens when the MAF is removed w/the battery still connected. The PCM would need to be reset if this is the case for others. The computer will eventually re-learn you're driving habits though...
