MAF waffle?

[Replica]

What happens if I cut out the "waffle", that net in front of the MAF sensor? It looks pretty restrictive.

 

[ZiO]

Dont cut it out. You wont gain anything by doing that.

 

[Kooldino]

It might not work right.

do it, be a pioneer. I bet it adds 20whp.

Only vteckhk can do that.

first dont cut it it just pops out, it must restrict a little tiny bit because there is plastic where there should be air i did it to mine a long time ago and haven seen any ill affects so go for it if you have nothing better to do just be very careful of the actual sensor

the baffle, not waffle is actually used to tumble the air before the MAF hotwire. Removing may not cause a CEL or any immediate problems but it was put in there for a reason. Unless ifelt smarter than the japanese engineers who designed it I would leave it in there.

What is the use in tumbling the air in front of the MAF sensor?

to get a more accurate reading. Air contains pockets of hot and cold air, by disturbing that prior to the hotwire the readings are more consistant. this is how I understood it from a GM training class I had to take. GM swears by these things and makes it to where the car won't run without them in place. It looks almost like mesh. If the other guy has noticed no problems then I don't think there will be any problems.

I definitely would leave it alone.

The only "mod" on a stock MAF is occasionally cleaning the sensor wire with CRC Electrical Contact cleaner. After you get about 10-20K miles on it (or if you have a really sloppy oiled up aftermarket air filter) the sensor wires get dirty and a blast of the cleaner can help out if your car starts to run sluggish.

very good advice.

I took mine out when I put my CAI on, and I have no ill effects. I personally think it's just there to keep retards from sticking s*** into the sensor when changing their air filter.

And yes, I do think I'm smarter than those japanese engineers

 

[Kooldino]

I just read a thread about this elsewhere recently. They claimed some big improvement. Mewants to see dyno numbers.

i took it out and also modified the stock intake to get more cold air flowing in from the grill. it dont think it adds hp, but it feels like it revs and drives a little smoother. i havent had any problems yet and i did that about 1000 miles ago.

The waffle could be there to channel the air flow in the pipe...there maybe a specific velocity profile the engineers at mazda wanted for the stock intake piece.

The turbulence of the intake its self makes the velocity. I don't understand the little grill/waffle thing at all. I'm new to MAF so (scratch)

 

[Kooldino]

Take out your maf waffle and put in your TORNADO DEVICE!

 

[jc_P5]

What i mean is that the waffle could act as a channel guide to distribute the air flow when the intake sucks in air. Think of it this way, on a conventional fan, there is always a unifrom grid panel on top to cover the fan blades, but it also acts to direct the flow in a certain direction before it reaches separation. This is just my observation of it based on fluid mechanics.

 

[Douggie]

Bear in mind that the MAF is not cheap to replace

 

[Mach 3.5 Turbo]

Honestly guys. The grating on a fan is there to keep idiots from putting their hand in the blade. Most fans they sell now just have a wire basket over the blades. This would have no directional properties, and they still blow air straight.

Mazda covered up the hole so you can't break the MAF without really really trying. Look around your car. Are there any sensors just chillin out in the open? Nope, modern cars are stupid-proof. They are protecting the dumb from themselves. Have any of you guys actually had any fluid mechanics classes? The flow would separate through the screen but then recombine again on the other side, just a little slower due to the drag across the surface area. Air is not like play-doh. It won't separate into "streams" or anything like that. If the thing channeled air to the middle of the MAF I could understand, but it doesn't. It's just a dummy-proofer! So if you are a retard and can't be trusted to not jam a stick in the MAF, by all means leave it in. I took mine out, because I know enough to not believe whatever people tell me.
