Hello!
I noticed a 1 cm gap between the airfilter and the topshell of the box yesterday!!!

Has anybody modified his box to stay closed all around 100%?

I couldn't afford a carbonbox for now, so I have to do some improvements by myself...

Yep, did the same and I hope the engine hasn't sucked dirt allready!
But I need a longterm solution, until I can afford the carbon version...

Maybe two belts around the box?

Shep please could you let me know who and how much for the carbon airbox (PM if you'd prefer) and would you put this mod above a set of new shocks, say Racing Reds - both are okay on my car at present, but i'd like to gradually upgrade whilst still leaving the rainy day money intact.

Have you tried adjusting the position of the lower half of the airbox . The front is located in a slot and the rear screws often have alternative holes or you could drill some .

@plasticman
It's fixed at 2 positions, 2 bolts on the back and one bolt on the front, mounted with a "curved slotted hole" and a long bracket coming from the engine block (I have no A/C!).

no alternative holes, but will try to move the lower shell to the top as far as possible...

About £820 for the Racing Reds + geo & fitting inc VAT (2010 rates) when I had my service last year. Airbox with Trumpets is £1050 inc VAT + fitting. Speak with Jason at Str8six, he will give you current prices for both.

I would do the shocks before the air box as the stock items are poor compared to the R'Reds. The airbox looks nice but not sure what I will get from it. IIRC the modified trumpets help airflow and its actually fits together as it should so this helps keep the crap out.

if the airbox mating faces are not very good, can you not fit another couple of clasps like the ones already in place?

@shep
Hmmm, thats a lot and I'm located in Germany - so maybe I have to go to GB for fitting. Thats a project for 2012... :-)

@Pu
it's ok - the carbonbox is the only answer to my question...

@clive
Yes, thats a possibility, but I'm a bit afraid of drilling holes in that shell. It's very thin and weak all around, so I have to strengthen it and then make the holes leak proof!

Can't you just black silicone it up?

I am currently making an aluminium frame for mine that fits on the inside too 'square' it up.

I am also replacing the clips for better stainless items, bolted on.

Trying to do the above without any additional drilling etc of the box so I can put it back to normal if required. Will see how it goes.

Cheers. Lee.

I have just removed the pop rivets on the clasps and drilled the holes out a little with a dremel... it's no where near as fragile as you think

I'm going to restart this thread.

Recently bought at T350T.and the airbox top was split.

I have sorted that out with a few neat fixes and as the old air filter (Pipercross) was falling apart at the front corners I purchased a new one.

Fitted the new filter this afternoon and I assume I have encountered an old problem others must have come across?

The airbox top has a lip that is supposed to fit inside of the air filter lip and the airbox flange is supposed to seal against the top of that filter lip on the front edge.

However, due to distortion from heat, the front of the airbox top will not seat into the filter and the underside of the airbox lip sits on top of the filter lip.

That means the airbox top fits correctly for about 90% of it's length and is then raised as it sits on top and not inside of the filter lip.

That scenario explains why the front corners of the old filter split and had to be mended with superglue recently as a temporary fix.

As it stands the top of the airbox appears to be too long to fit correctly everywhere.
I tried fitting the air filter to the airbox top whilst both were off the car to see if it will actually fit correctly and the distortion makes that impossible.

As others have stated the front of the airbox is attached to a bracket that can be adjusted to get fit of airbox top to intakes and to lower half just so.
Takes a few careful attempts to adjust it just right but easy enough though.

Anyone found any ways to get the top and air filter to fit perfectly all round?

I ran out of daylight this afternoon so will investigate further at the weekend and may even consider modifying the top to get a perfect fit, which can only improve running with no gaps for extra air to be sucked in.

Cheers,

Steve

Your airbox sounds like my old warped one. I fixed mine by getting a better fitting 2nd hand one. I tried to un warp the original but its aged plastic just cracked and split at the filter flange. An alloy oblong bonded into top and bottom half of the filter case might solve it.

Thanks for the reply.
Yes, it is a little warped here and there but a bit of clever fettling may solve my issue and will be cheaper than a secondhand replacement.
Will post more once further work has been done.

Problem sorted.
Careful look revealed that the lower half of the airbox was siting too far back in relation to the top half.

I bent the lower half front and rear mounting brackets a little by hand, in situ, so they sat further forward. That meant the rear bracket was angled forward so I then had to slot the lower hole of the rear two holes in the airbox lower half a little to get the bolt to fit without forcing it.
Adjusted the height of the front and bolted everything up and my new air filter fits snugly between both haves as it should making a good seal.
On the front adjustment my bolt is half way along the long slot in the bracket and that produces a good assembly that does not put any stress onto the intake trumpets. That avoids any chance of introducing cracking.
A small mirror is useful to check everything is fitting nicely at the rear of the airbox etc.
