Addition to snorkel removal
 

Remove snorkel. Drill 5x 28mm holes extra holes, plug up side holes using vent caps.

The air filter area is = 9768mm sq the snorkel hole area removed = 4000mmsq by adding 5x extra breathing holes you are able to use the full effect of the STD filter size, without the out lay of a DNA stage 2 filter.

Remember to clean out the airbox well.

You will need to adjust the fuel injection richer, using a power commander or the Kev Fueling Mod.


Works well for me.

Why didnt u drill the wholes in the removable panel Kev.
This is irreversible and the panel can easily be renewed ????

The removable panel is part of the filtered area of the airbox & would need the air to be filtered, if using this lid.

The vents I used are not filters, they allow full unfiltered air into the airbox up stream of the air filter. Manly to get the most amount of air to the air filter. If you remove just the air snorkel the filter is still very restricted. The air drawn into the airbox should be equal to the filter area, but it is only half, if the snorkel is removed. So drilling extra holes make sense.

You can buy 30mm rubber grommets from any hardware to block up the holes when you sell your bike.

So even with my stage 1 K&N and stage 2 DNA fitted, these holes would make a difference in air stream i guess ???
Cause i have a few left of my previous side panel conversion and without the little filter they would come in handy then........

The best air intake system is 1st K&N + 2nd DNA stage air filter.

This mod is used only if you don't use the DNA 2nd stage filter.

Remember you will need to adjust the fuel injection richer, using a power commander or the Kev Fueling Mod, to get the best result.

Just pulled my snorkel out with no other mods tried the bike and almost flipped it what a difference dont know why as its not supposed to unleash the devil but it did on my bike, well happy

kEV, WHAT ABOUT THE 07 MODEL WI THE LAMBA....CAN THESE MODS STILL WORK ok a take it a`ll not need any fuellin device....John

Should be no problem with filters & snorkel removed.

If the bike runs to lean & lambda control can not richen it up enough the engine light will come on to warn you & a fault code will displayed on the dash.__________________

Finally gotten round to having a look into snorkel removel. I've taken the panel off the side of the bike where the air box is and there's some oily residue there, I'm assuming that's from the filter itself, is it something to worry about?

I'm going to hoover the dust/dirt off the filter itself, and I'm also thinking of applying some of that protective oil I've got from my open air K&N car filter?

Any thoughts chaps/lasses???

Is your filter actually a K&N or is it the OEM, cause if it is, you can't clean or regrease that one, you or your mechaninc will change the OEM every 6000 miles service. The oil residues in the air box are a normal thing, you will notice that there is a drip pipe for that at the bottom (under it to be precise) of the air box for this purpose.

No Capt, I have the OEM filter on my X, but I have a K&N on my car and have the cleaning/oiling agents for it, that's why I asked. Is the filter below OEM or aftermarket? I've got a worrying feeling that mine has been put in the wrong way around? That is the side that metal mesh grill is facing on mine....

Wow, normally, due to the triangular shape of the slot there should be no way to fit this filter the wrong way around, unless someone forced it in that way. The metal grill should face inwards. Right, as I said before if your filter is the OEM then you can't do anything about it, as it is a disposable paper based one and if you treat it with grease you might only damage it. Best thing you can do with it for the time being is tap it and try to clean it with an air compressor, not too close to the paper, but I do suggest you get a proper K&N or DNA from our friends at CCC (who will sell you stage 1 and 2 at a discounted price).

Have a look at this thread Denny

Just to eradicte my paranoia, this is the right way around aint it?

What does the CCC stage 1 or 2 consist of Capt? My next mod was probably getting a Pipercross filter locally and ordering a DNA racing air box cover from OTR :toothy6:

*edit* looks like CCC are revamping their website

Stage 1 filter will only fit in one way.

Stage 1 & 2 filters. http://www.dnafilters.com/newsdetails.asp?newsid=30

Sorry to drag this one on and go slightly off topic, I'm about to order a Pipercross filter locally a DNA racing air box cover from OTR.

However it seems the DNA site recommends getting a power commander to notice any change in those said mods. Is this the case, I already have CCC cans & the snorkel out, will I not benefit with the filter & DNA cover?

fanks guys :la:

The filters & air box mod will produce the most power gain of all the mods. I would also recommend a Power Commander or other type of fuelling device with all your mods.

Have a read here.

Advanced mods, for the more technical minded.

8/ Fuel devices.

I've been pondering whether I should do the air box mod you've detailed, but one thing that worries me is water being sucked into the engine through the holes resulting in hydrolock. I know the filter is there to prevent that but there is only so much that it can hold back, even with the snorkel removed I'm concerned as there has always been water around that area when washing the bike?

I have a K&N cold air intake on my 306gti which sits very low to the floor, and I've heard some horror tales of hydrolock. IIRC the cone filter needs to be fully submersed up to %30 for water to seep in.

Or am I just being overly pedantic?!

All I can say is the air box is made up in 3 stages & the bottom stage is designed to store water & to stop it splashing up on the main filter.

If you are using a K&N or DNA stage 1 filter they are oil based filters & will not let in water through, unless they are completly submerged in water.

I have sold over 40 fuel air box mods & have never had any problem, I have run with this set up for nearly 2 years & have not had a problem. Water does enter the air box when I wash my bike, but it runs out the drain. I have ridden in heavy rain & have found once removing my seat that there is no water on top of the air box.

In the end it's up to you.

Excuse me, I do not speak English and I am using a translator (google) if anyone understand what this writing, no problem.

Here in Brazil is not very easy to buy the K & N Filters and DNA, so my bike is using original air filter.

If I only withdraw srnorkel, I gain some power?

Thank you and excuse me for bad English

muito pouco ganho (I have used a translator too)

You will get about 0.3 of a HP. Not worth doing unless you drill your air box as well. http://www.xt660.com/showpost.php?p=27447&postcount=2

Order stage 1 & 2 filters off the net well worth doing, you will get around 3.8HP with both filters & snorkel out.

Thanks for answering and again sorry for the bad English (I only understand a little but I do not know speak).
I will buy the filters of air (k & N and DNA second stage).
I do not understand if only we withdraw the snorkel or need to do anything else.
Need reopen some hole?
If someone has pictures would be easier now I understand.

Thank you!

Hi Kev.

How much more power will you gain if you add the DNA stage 1 and remove the snorkel and more air holes in the airbox, vs. stock airbox with just a DNA stage 2?

Is it worth the extra holes and removing the snorkel if you already have a DNA stage 2?

Freez have a look at this link, I have put the gains for the mods I tested over the last year.

pulled the snorkle out and turned up the co's from 8 to 13 wow wot a differance did not drill the extra holes in the air box will prob do that next time i mess hopefully santa will bring me a dna stage 1&2 filters :Speedy_Superhero_Q3

Good one Peter, you will feel a great difference when you fit the 2 filters specially since you are using after market cans. (Microns)

Original or After market filter ?
 

I've just pulled the snorkel and boosted the co from 20 to 28, no other mods have been done and i have to say the difference is quite noticeable especially low down. 2nd gear has really got some snap to it. Grand!

But i have a quick question regarding the filter, is the standard one louvered or does it have a mesh covering, i had a quick look in my airbox and the filter has no mesh and has louvers like the ones at the start of this post. Also there is a K&N sticker on the airbox, could the previous owner have left a K&N in there?

If he did ; Nice One Adam ... :icon_thumleft:

I don't understand what you mean by louvered, however the original filter would have a metal wire mesh on the outsdide, whereas an aftermarket one like the K&N or DNA just consists of ribbles of a special compund that looks like cardbard in a concertina fold and wrapped in thin mesh, it is safe to assume that if there is a K&N stickers in there that it is infact a K&N filter.

Louvered. Sorted !

Should i bump the co up a bit more? the bikes still a bit lumpy, not sure if the sub zero temperatures up here are having an effect [-4C this morning].

Cheers.

20-28 is more than enough (I think) I would invest in a Kev Mod to enhance the fuelling of the bike, have a read around the forum about the Kev Mod and see what it does to you at such a cheap and affordable price.

Cheers

Ello!
Would someone be so kind and post some pictures where to drill that damn holes? Im such a nOOb, Im sory...
Thanx!

sound!!!
 

woooow with snorkel removed and extra holes the sound has totally chaged! :icon_biggrin::icon_biggrin::icon_biggrin::icon_bi ggrin::icon_biggrin::icon_biggrin: i didn't expect this!

I dont wanna drill the holes 'cos it bypasses the air filter and i'm going somewhere dusty.

What purpose does the snorkel serve originally, why was it ever fitted? Is it to prevent small thing, bolts etc. falling into the airbox?
