So I saw that there wasn't an actual tut on how to Swiss Cheese your air filter, like a GOOD one, one for people who have no idea what to do. Not just a picture and be like "DRILL HOLES THEN PUT IT BACK IN AND YOUR DONE! WOO!" Hope this can help others, since I couldn't find a tut on it.
Also Once your done or want to hear what it sounds like heres a link of me driving after I was done: http://www.youtube.com/watch?v=uFfdyORaWiA
Keep in mind this is a BARE Stock Golf. No K&N Filter either. I think its Fram haha.
1. Flat head screwdriver
2. Phillips Screwdriver (Optional I didn't use one)
3. Latex Gloves (To help keep a lot of grease off your hands :])
4. Electrical Drill
5. 1in Drill bit (I'm sure you can use any size, just make sure its big.)
6. Broom (To clean up all those stupid shavings)
7. Some type of Cleaning product (If you wanna clean stuff off while its off ;])
What you want to do is take this clips off. Theres on on the front and rear of the filter.
Not a real problem at the moment, but you can take these rubber bands off their clips.
Take off the little diagnostic thing and the two small pipes going into the right of it. Just wiggle those out. And before lifting off the top piece, make sure to unscrew the intake pipe. Up top (second pic)
I had some oil inside mine, I just wiped it off. I'm sure someone here could tell me the reason this happened, it didn't seem like a big problem to me, so I just moved on. I took the top and cleaned it a bit.
Simple, Just pull out the air filter (If you have a K&N and its dirty, wash it.)
Move all the top wires and misc things out of the way, just tuck them under something.
1. Small tube connected to the lower half of the Box
2. Small clip also connected to the lower half.
3. A small rubber seal that just slides on and off of where it stays. (Its easy to just take that flat head and push it off. Putting it back on is easy.)
Take all this stuff off and take the lower half out aswell.
Grab Drill and Bit.
Warning: Careful with the bit. I almost tore a hole into my own hand.
Start drilling holes into random or more uniformed (Like mine is sorta) holes. Stay clear of the reinforcement struts on the sides, it gives the box structure and support. If you WANT I've seen people drill holes in those too. Just don't ruin anything that goes back on or you still need.
Enjoy that Drill and bit a while more. (IE: Drill into random pieces of wood, metal, plastic, ect.) Careful not to drink when doing this. Could turn out bad
Admire your destruction.
Begin rebuild/Re-put-the-hell-back-together. Don't forget to put everything back where its supposed to go. Those rubber bands and the little pipe things. And finally the top half goes back on make sure everything is on good and tight.
I hope this tut helped. I'm afraid I don't know all the TECHNICAL terms for things, but this should be helpful to all people. No matter how much you know about VWs.
If this needs to be moved to DIY, I'll do that. But for right now. Hope you guys think my Tut was satisfactory. If theres a better way to do this, please tell me :] I'll edit the post and refer those to others suggestions as well.
