Replacement Air Filter
Discussion
Has anyone fitted an aftermarket air filter to their S?? I have an S2 that I am currently doing some work on tarting up the engine bay and would like to fit some aftermarket air filters (K&Ns etc..) The main problem as I see it is that in order to fit an aftermarket air filter, two adapters would be required to convert the square hole on the AFMs to round ones to fit the air filters onto. I have equired and have been told that these items come with the K&N filter kit for the sierra XR4x4 but trying to fit this kit may cause another problem. As far as I can remember the AFMs on the Sierra were side by side and the S2 are one on top of the other making them closer together and possibly too close to fit this kit. I would be interested to know if anyone has solved this issue and what they did to solve it?
Yes I did this to my S2 a while back (K&N 57i kit), I had to fabricate new brackets to space the meters apart by about an inch, not rocket science but a pain nonetheless. To be honest I would fit a new Pipercross Filter from TVR (I fit these on every car I service), they cost about £35 and will probably flow just as well (they use them on race Tuscans!).The 57i kit I bought was about £125 and you don't use the bracket that comes with the kit which is a waste

Thankyou for your reply Lee. I am presuming the pipercross filter from TVR will be the same as the one that is currently in bits in my garage (it literally fell apart when I took it off). I have two problems with this filter, firstly I`m after looks and I think that the filter that was on before looked like a horrible lump of foam. My second problem is that I will not be connecting the oil breather back up to it so the point where the breather pipe would/did fit is no longer required as I`m going to put one of those small crankcase breathers on!
I think I noticed once on the K&N web site a filter that had two round openings on the back which may do the trick. Have you seen such a filter?

When I replaced my air filter with a TVR original (piper cross), i was told that i would have to cut a new hole for the breather pipe connector, which wasn't a big job.
Roy, what sort of breather were you going to fit, is it similar to the Ford one in the offside rocker cover? Where were you getting it from? Sounds like it could be a good idea to make things a little bit neater.

The breather filters are available for all over, from places such as Demon Tweeks. They are just like a tiny version of the usual air filters and they fit onto the oil filler cap.
Speaking of tidying things up, I am also swapping the rocker covers round (as they were when used in the Sierra) as this allows me to shorten the pipe that comes off the other rocker cover to the plenum. The only reason I can think of as to why TVR decided to put them the 'other' way round is that the oil filler neck could get in the way of the large clump of pipes in the area around the swirl pot. Anyone know if this is the case?

I have just fitted a TVR original & the breather pipe hole is no longer there, so no problems with that. Where do I fit my pipe though!

None of the pipercros replacement filters for the S ever came with a hole and fitting in the side for the breather pipe.
You will have to take the fixings from the old one and make a new hole in your new filter and fit it accordingly .... or .... get a 3" length of Garden hose and a K&N to atmosphere oil breather filter and tap it straight of the rocker cover. Works a treat
Save the AFM's aswell. Just remember that on a track day the car breathes much more heavily and you are better advised to fit a catch bottle for this activity. Learnt that one, nearly the hard way

So whats a catch bottle then?

Johno, why fit the breather filter on a 3" length of hose? Couldn't you just fit it straight on to the air intake where the original inputs (side of filler cap)? Or is there a good reason for the hose? Just wondering because i was considering fitting one.
Got my Pipercross air filter from David Gerald's, it cost about £30 i remember correctly. You may be able to get them direct though, try giving them a phone. I have the part number it you need it.

3" of hose was from the Oil Filler Car into the breathe filter. It is the only way you can connect the 2 items togeths.
The oil filler cap end will be an overfit to the pipe, but the other end will go inside the filter. 3" gives the whole assembly a decent balance.
It also holds the filter proud from the filler cap slightly.

There are 4 things you can do with your breather ...
1 - Too atmosphere filter as described below...
2 - Air filter assembly - standard
3 - Take the pipe off the air filter and run down the passenger side bulkhead and tie wrap to the chassis under the passenger seat. This will then breathe oil over the chassis. I did this for four months too get it all nice and coated underneath.
4 - Catch bottle ... A Catch Bottle/Catch Tank is where a hose from the breather is taken to a bottle/tank and the breathed oil is captured inside whichever vessel you use. Paceracing's S2 had a Sprite bottle that was his Catch Bottle and it worked a treat !!! You do see this a lot on race engines etc etc It does allow you to measure volume of breathed oil etc etc and prevents the oil from going anyway other than in that vessel. So not on your tyres etc etc ..
