Anyone got any ideas on how to stop the air filter on the 11s clogging up?

Had mine out yesterday and there was half a fields worth of mud and a dozen flies in therewhich obviously isn't good.

Try fitting some finer mesh in the intake holes in the nose fairing.

... leave off all of the induct..
doesn't funnel all the crap onto the filter.
Also means you can get at the filter easily (and the batt. to some extent)
I just run with an ordinary paper filter, just in case a K&N would be too weak.
Plugs seem to be OK colour.
Sounds rortier too.

Nookie,I think you are getting your Air and Oil mixed up and Simon wash your mouth out, you can`t expect people who have stumped up £250+ for a lennies induct to leave them in the garage, sacrilege.

... ya pays ya money an' ya makes ya choice..

.. a £250 toob which passes more air and presumably puts more carp on the filetter, which restricts the airflow through the filter, negating the benefit of more air.. Plus there's more dismantling to do to get at the filter.. which needs to be done more often.

.. remove the toobs and use a £14 paper filter which lasts an age. It's what I refer to as my ENC induct . Plus can change it (and see the state of it) by just taking the side panels off.

I remember the first time I took the induct off and saw all the wild-life that had ended up there.

Man's got a point. (or 3).

Makes sense to me, there no point channeling all that air into a blocked filter as mine was.

I'll give it a go and see what I think.

Tie wrap a sock over the end of the induct to keep out the grit, straw and assorted large lumps that seem to end up in the filter. Tie wrap or gaffer tape it so it don't get sucked in

Took mine out over the w/end and it was black and full of wood lice from my garage dead flies etc so might have to agree with simon, TTT wouldn`t putting a sock over the end defeat the object as well, tights might be a better idea, but don`t tell the wife.

tights might be a better idea, but don`t tell the wife

... don't have one of those
.... and if you think I'm going into M&S and asking for a pair of Pretty Pollys you've another thing coming..!
(Well not without the full slap and slingbacks anyway )

Pound shop to the rescue pan scouring pads the type without foam wotk a treat

Pic below: this is what I use to keep half of the landscape out of the pleated filter on my 928 Porsche. The air intakes are abt a foot off the ground and at full roar it hoovers in 200L/sec of stuff - tiny birds, locusts, wallabies, slow children, the odd wombat ... Unfortunately it's illegal here to try for lycra cyclists.

Very easy to look after on the 928 but an absolute bugger on the 1100.


I like TTT's idea of a sock over the snorkel mouth but it comes with the problem of airflow restriction.

To give more breathing area, let the sock into the induct by a foot or so, but to stop it sucking flat against the sides of the duct, put it inside a 'cage' made of bird cage wire wire, about 3/4 the diameter of the intake duct. Intuitively I'm confident it will work. Easy to measure air pressure difference across the sock.

(Note to self: remember bird cage wire when next at Bunnings)


Come to think of it, the same concept should work in front of the oil cooler.


Thanks TTT.

Hi all
Val singletons filter mod( do a search) or san Jose filter. No blocked filters and you run a air duct as is required. Or stop being lazy and service your filter more often. Removing ducts and fitting socks is backward engineering...
All the best

A 'no block filter' ...

Something a bit oxymoron-ish there methinks.

Well just today I've fitted those induction toobs I made from B&Q drainpipe* , put in a nice new air filter with some of that very thin gauzey stuff over the top and left the inlet trunking off Then it started raining sooooo; I locked the shed and went indoors.

* For those of you who have been following the 'Drainpipe Drama' I eventually managed to put a curve in 'em by sliding 'em over a length of very thick dia. rubber hydraulic tube (that fitted inside snug) off a digger that's in the workshop and bending it whilst I blasted it with my trusty heat-gun.
