I replaced the K&N air filter in my HDI Xantia yesterday. I know these are supposed to give better breathing and last longer than an original. However, part of their design to filter air is to have a film of oil on the filter. In my opinion if more air is getting through then so is more crap from the air. I always like to stick to proper filters so replaced it with a new Purflux one.
I then cleaned the MAF sensor with some air intake spray, it was quite black which is common but I wonder how much of that is oil residue from the K&N.
Its done 80 miles this morning and feels if a little more lively, no doubt due to the clean MAF sensor. Its economy seems slightly improved too (easily measured on my the trip computer). Replacing the K&N with a proper filter has certainly not decreased performance!

I think Chris is right. I even looked at a Volvo.
Do you miss your C5 Mike? Not bad cars as you know, cheap to buy and run and generally reliable in my experience.
I'm all for comforts, refinement and a good ride in a car, hence my car choices
I do miss it, yes, but it went to a good home as my brother really needed a decent car to transport my newborn niece around in. RUNN had died, and their other car is a Ka, which, while fun to hurl around isn't really a lot of use for carrying all the baby gear around in comfort and safety. He's well pleased with it.
I was always in the position to have one "family" car and a toy, so it didn't really matter about the ride quality. It does now though..
I've come to work in the Berlingo the last few days instead of the Subaru..

Obviously, there has to be a happy medium between crap getting through, and air getting through. I don't believe that standard filters provide the optimum, but then again, nor do I believe that K&N or similar make that much of a difference, if any. Subaru forum people (for what it's worth) like those Green Cotton filters. K&Ns and early Subarus seem to be a bad mix. As you say, oil from the filter gets on the MAF and damages it. Mine's got a Halford's special in it at the moment as the one we took out at the weekend was foul.
I always perfer to keep things like that standard and I've yet to be convinced that changing the type of air filter has any improvement on performance. Certainly not with this car.
Weve had a slight delay on the C3 Picasso collection, due to some time constraints with the dealer it will be Thursday or Friday for the change over. Never mind, I had filled the C1 up with petrol on Friday so I get to use a bit more of its fuel, it'll be my commuter car tomorrow

I think on a standard car, you're right. If you start getting into engine mods, especially with turbo cars, you can be demanding a lot more air and fuel , and then IME they do make a difference. Certainly did on my old Saab, but that was running 60bhp more than standard, big injectors and a non-standard turbocharger. It was a bit choked with the standard filter, I ended up with some blue thing that cost about £35 back in 2005

It was one reason why I let the 205GTi go.
I do like my comfort...
Hey, its not an age thing I've always liked larger and more comfortable cars over a harsh and sporty thing
I do keep thinking, hmm, maybe I should get something which is more driver orientated. Then i go in a friends car and I'm reminded how much I miss the Citroens abilities. The Activa does for me, it can beat almost anything you will come across down a real world back lane, yet its very refined and comfortable while doing it and is a great long distance car too. Suits me!

It's a shame you're not nearer Chris, you could have a go in the Impreza. It's so much faster than the Activa on any sort of road - it really is in another league. However, that's what it was designed to be... it's not refined at all but it is a real drivers car.
If I had an Impreza I'd either loose my licence or something much more permanent! Which is actually my only complaint about the Activa, its a very good system but for me to have fun with it the speedo does tend to be quite far round.
In contrast to that ...
I've done my commute in the C1 today, what an excellent little car they are. Great fun to drive, an engine with character and not at all bad on the motorway. They are even well geared for a 1.0 petrol engine, 70 is about 3400rpm and is very civilised at motorway speeds. Its a joy to drive enthusiastically and your still legal with it. If I was in the market for a small and cheap to run car, I would not consider anything else. I will really miss the C1 when it goes either tomorrow or Friday.
The C3 Picasso should be ready to collect tomorrow or Friday, not quite sure yet. I'm looking forward to seeing what that is like, I think it will fit in with our lifestyles just perfectly.

I actually don't think you would, it's a car that you tend to drive very sensibly where it would be visible that you may be being a little enthusiastic! I drive it very sensibly around town, but then it's easy (on a racetrack of course) to hit silly speeds on country A and B roads with so much power.
Unbelievable as it may sound, it's easier to get an Activa on the ragged edge than it is with the Impreza.
It's Bl00dy uncomfortable though. Now, where can I get a 260BHP Activa?

It is quite easy to get the Activa on its limits by pushing it needlessly. However, keep it smooth and the grip is simply awesome. In the dry. Hmm, I really fancy a drive in it now
Will the Impreza engine fit into a Xantia?

I lost the rear end of an Activa at J7 of the M4, coming off the Eastbound bit, gave me a rare old scare! Fortunately there's two lanes and it sorted itself out. There's not a huge amount of feel is there?
I sense with a few mods - decent remap, turbo, injectors, fuel pressure regulator and a decent intercooler, 240bhp or so could be squeezed out of a Activa motor. The old Saab 900 T16 could be tuned very well up to 350+bhp reasonably reliably. Sadly the gearboxes couldn't really take much more than 220, as I found out to my cost.. They put them in newer Saabs to make Saabarus, but I can imagine even Jim couldn't get one in an Activa. It's a plumbing nightmare as it is
