I currenty have a KnN panel filter in my 8v and just wondered peoples opinions on weather its worth drilling the airbox? i did it on my mk2 and it sounded like a beast, should i be expecting the same sort of sound? does it decrease fuel economy?
-
will make more noise but thats all it will do, oh and it will also let more dirt inside the box too :nerd:
-
cheers kells, yeah the letting the dirt in is the part im concerned about lol i dont know weather to do it??? if i drill less holes in it will it still sound the same or has it gotta be swiss cheesed :smiley:
-
if you drill under the filter it cant suck no dirt up :smiley:doesnt make really loud ,i took the extension piece out that goes to the inner wing instead off drilling holes ,didnt notice it much so i put a k&n on instead
-
im more than happy with my K&n 57i, i know alot of people on here prefere the standard airbox and panel filter route but i personally dont see the point in it at all in terms of performance upgrade, i know a induction kit will not give a gain in bhp if we are all gonna be honest, but it did make my car run a hell of a lot better and it sounds great, and will last forever too.
just make sure you feed cold air to them and u cant go wrong..
-
hmm might just have to try it and drill it out like the guide in the maintenence section. :undecided: i just dont want it sucking in crap or water, at least if i dont like it getting a new air box wont be hard
-
Do it mate its worthwhile.
-
come on len lets hear your reasons, where is it best to drill the holes? maybe wing side only?? how much louder does it sound to stock?
-
Well first rolling road I ever went to with my Golf there was 2 other Mk3's there and both had drilled boxes. They both made better power than mine. (K&N cone) (although it wasnt set up right at the time!)
So I cant really say what the noise was like, but from a power point of view its definitely worth doing!
Yes I would do the wing side only. If you do the engine side you only draw in hot air.
-
Cheers len, your rather helpful, i think its gotta be done then, drills at dawn on sataday :grin:
-
Drilled mine wednesday and its been fine. Sounds ok oh i do miss the noise of my Vr :cry: :cry: :cry: I can feel a new exauste coming soon.... :wink:
-
how much more can you hear it? as on my mk2 you didnt really hear it until you put the load pedal right on the floor at any revs then it sounded like a beast :evil:
-
Did mine about 2 weeks ago after ALOT of hmm'in and ahh'in..
All ic an say is DO IT! Sounds much better when on full throttle and sounds nice and quite when driving normally.
-
Richie.... Did you drill the whole bottom box out or only the wing side??
-
Personally I would only drill the front and the wing side.
I reckon doing the opposite side and possibly the bottom would draw warm air in from engine reducing power.
I'd definately avoid doing the inner side whatever you do mate :smiley:
This is a useful guide-

Although he seems to drill on the engine side too? :undecided:
-
I only drilled the bottom and the side near next to the wing so that you couldnt see any holes when re-fitted!
Took all of 10 minutes to do from start to finish
-
From what ive read drilling only the wing side works best aswell as running a cold air feed to the back of the air box and fixing it to where the warm air feed goes.
-
Do you think it would sound as loud if i only drilled the wing side as opposed to drilling the wing side and the bottom??
-
mines only drilled at the wing and sounds nice under throttle..... The vento i have has had most of the airbox drilled wing side and bottom and is defo louder...
-
Nearly every car I've had the drill comes out and attacks the airbox.
I only do the front and wing side as other wise it just sucks in hot air from the engine.
On some airboxes there is a restrictive air intake (mk2 8v) if you take that out it makes the induction noise louder. It's a nice easy and free mod!
-
does a mk3 8v have a restrictive air intake?? if so how do i remove it? :smiley:
-
so the question is do i drill the bottom aswell or just the wing side?? will it suck hot air if i drill the bottom?
-
Just drill wingside for noise and run a cold air feed to either the back of the box or remove the trumpet in the front of the box and run the feed to this.
-

You mean the air box? or whole air system?
-
mikester i think hes referring to the trumpet section within the airbox, which yeah is restrictive,
I cut out all the fins inside the box and removed the trumpet too mate... have a look through the guide thats been posted up here
-
I finally did it this morning after alot of hesitation and im impressed, i only put about 6 20mm holes the wing side only and now when i put the pedal down it growls, i wouldnt say theres any noticable difference in performance tho, worth it for the sound :cool:
-
Drill away the bottom a bit for noise, fit a cold air feed from the bottom splitter up past the alternator, bobs your uncle.

blimey....where u going to hit all these birds :grin: :grin: :grin:

i drilled the box in the vr, sounds far better and lets more air into the box, just need to sort a filter out. :smiley:

I drilled my old Vrs air box it sounded ok but when i put an induction kit on oh my god sounded like there was a animal under my bonnet, a big one with pointy teeth... :grin:
-
My Car was stupidly loud....
I did a mini service changing filters etc, opened the air box and the filter in there was tiny!
I put a correct fitment one it, and while i was there i found that my airbox was drilled!!
With the correct filter though it sounds a little quiter!
It is still very loud though!
-
do you buy the cold air feed or make one also what would happen if you had 2 holes at the front of the box next to the wingside
-
you buy one. Ebay sell them cheap.
search cold air feed.
I took the snorkel out of the front of the box (the main air flow feed) and ran my cold air feed in there with gauze on both ends of the cold air feed to stop sh!te getting in.
-
and then run it down where by the front bumper ?
-
I've run mine out the front of the air box.. then down to the vent in the front bumper (next to the air temp sensor) I only used a small mount of cold feed pipe (which i got from work haha - better quality aswell)
-
haha sound dont blame you ill give that a go to thanks again
-
do the gauzes cum with it or do you buy them and put them on yaself
-
I got mine from work lol...
not 100% sure where u can get them from... but you could use a Sivv... and cut the gauze out of it and fit it to the cold feed pipe with a jubilee or cable ties??
-
haha top man im doing that right gotta go pick up the gf test drive my car 2 lol thanks mate
-
lol no problem.
You should maybe speak to the other half before you go cutting the sivv though lmao :grin: :grin:
glad to help.
-
hahaha yeah i will i done what you said yesterday my petrol was on the white just above the red drove 9 miles and my petrol was still on the same as it was at the start of the drive put a tenner at the garage today took me to half a tank drove around 2.5 miles and it had dropped more than the 9 miles yesterday wtf is this just the crazy ass tank and i drove the same style both trips nice and easy lol
-
there you go, you have the same problem as all the mk3's...
dodgy fuel gauge. haha.
-
yeah i no ive got just under half a tank now and havent been petty station lol also mate do you no anything about the clocks digy ones where the fuel miles mpg temp and that are im missing half the middle number so when it says 313 as the time its like 3 3 so i cant see anythink in there would clock swaps work or is there another fix cheers
-

You could get new clocks, as they are quite cheap, but you will need to reset the mileage to yours on them.
-
ok cheers mate ill luck into it
-
If you have drilled sh!t loads of holes with a 30mm hole saw and plenty of 12mm holes to make it loud with a standard paper filter, is it going to be louder with a aftermakert panel filter?
I fear mine is going to be too loud :embarassed:
-
ive got standar paper one with six holes wing side and its quiet till you get high revs then sounds nice
-
6?
I have about 100 no joke. all wing side, I honestly can't drill any more holes.
Oh and just bought a pipercross panel filter for £34.85

Rather than lots of little holes I just cut away large sections of the air box, works better that way in my opinion. I need to get pics up!
-
thats next on my list of to get

True but I wanted some structural strengh. I started off with small holes then after a week I went mad with a 30mm hole saw.

What structural strength? It's not a building, doesn't need that much strength :tongue: I left the drivers side and some of the front and back untouched though so it still has strength.
