What did you do to your Polo today?

Installed the Verdict bushes. Definately a change in the feel, a little more precise. Its good to get under the hood again.

Whilst I was there, I did a few little things, tightened the clamp on the TIP, removed the grid on the back of the MAF and cleaned out the air filter. I'm not sure which one of these made the difference, but the little girl has a little more torque down low and seems to come on boost after a gear change a little more seamlessly. Could just be that I cleaned some junk out of the MAF when I was removing the rear grill...

Tell me more about the MAF grid. Why is it there, what benefit removing it, etc ....................??

If you pull out your maf, there are 3 grills. 2 before the sensor, 1 after.

The point of the grills as I understand is to keep a consistent flow of air past the sensor, so it is not affected by turbulance.

When tests are done on the 1.8T's, the restriction shows up in a number of areas. The MAF itself is one of these restrictions, but you don't want it working poorly, so its not recomended to remove all the grills.

I removed the rear grid as I don't see it changing the airflow as its post the sensor and is no doubt adding a small amount of restriction to the airflow. Not much to it, used some wire snips around the edge of the grill to snap it off, it is designed to unclip, but would not come out for me.

Actually - air tends to flow and twist between points. If you want air to flow smoothly over a particular point, you need something before AND after it to ensure smooth flow.
I've no idea about the MAF or these grills (never looked, nor would I have the equipment to test etc), but the grill afterwards could be as important as the grills before...

I don't think the flow is even past the sensor anyway, thats why there are lots of other sensors, so they can all work togeather.

I don't know what effect it will have, thats why i'm testing it. Will do some logs of the MAF flow at some stage to see if I can see any irregularities.

Cleaned and oiled my air filter, had to remove the strut brace again...

Contrary to what noone is saying, it isn't for affecting the turbulance of the air.

Instead, the answer is much simpler... they are there as a final safety barrier to prevent damage to the MAF.

This weekend I wrapped my door handles with 3M Di-Noc Vinyl.
Looks kinda ricey in the pic, but much better in real life. Next, the centre console and air vents, if I can figure out how to pull them out without breaking anything.

Looks pretty cool to me! , would look pretty cool on front VW badge if can be done. I would love to see the vents and centre console!!

Like I said, there are 3 grills. I removed the grill POST the Maf.

There is no point to having them for protection, its straight after the air filter, if it got through there, you've got issues.

I have read people wanting to remove the grills but deciding against it due to the possible MAF readings from the Turbulance. If ou read one of the early threads on the Seat intake, someone had looked at all the restrictions, the MAF was one of the big ones.
