Airbox improvement with maf mod

[Harry_LeonCupra]

Today, I took time out for this mod everyones ranting on about, I already have the k&n panel filter but didn't do much for me so I started by disconnecting everything and taking all the air tubing off including the air box and filter. I then took the 'snorkel' off the top half of the box, I then took the maf off and took off both parts of the mesh, I then smoothed out the inside of the box, deleting all plastic in route of the air flow using snips and electric sander. I then drilled a few holes for a new cold feed which I am yet to finish. I am going to use the snorkel as an exit from the box to get another air feed in...

What a MASSIVE improvement!!! The car is no longer sluggish and laggy, very very torquey now and the dv sounds pretty crisp with the n249 bypass. I am very very pleased with myself, such a difference at no cost at all.

Give it a go!!!

You should have taken some logs, only way to know the difference.

Also, I would advise you to put the front mesh on the MAF again. They are a very fragile piece of equipment, if a piece of sand or whatever gets there, big chance you need to buy a new one (they dont come cheap). On boost, the amount of air sucked in is huge (and travels faster than you think).

Also the extra sound doesnt mean performance Dont forget they Audi/VW technicians have put a lot of R&D into these airboxes, so the air gets sucked in fluently and without much turbulence.

On a populair dutch Seat forum, we have a member which puts out 380Bhp on the wheels with the stock airbox with paper filter. The only thing he did was removing the snorkel and opening up the hole on the side a bit.

My 2 cents on your mods

i agree....get the mesh back on asap

I think the mesh channels air so the maf gets a consistant flow over the sensor. without the mesh you run the risk of turbulant flow giving less accuracy.

I think logs were done on smoothing the airbox before and there were no recorded gains but if it feels better you must have done something right
