07 1.1 Air Filter Sizing

Hi all,

I'm having an issue trying to determine the correct size air filter for a 07 1.1 C3?
I've been onto Euro car parts, and there are 2 different sizes.

I would check original but don't have access to car.

Lastly, is there much difference in terms of Bosch branding to Crosland etc?

Cheers

Hmmm I thought all the air boxes on these models were the same?
If you provide your VIN we can check.

Are you saying cheap Vs expensive? Yes.
However this is a sliding scale. Try to stick to known brands within your budget. The Cheap no-name brands tend to be inferior in performance and quality.
Having said that there are areas that are important and areas that aren't. For example air filters, pollen filters, oil filters and brake pads.
I have found that even cheap air filters and pollen filters do a good enough job and really don't have a failure mode ( what could possibly go wrong? LOL). As far as oil filters go...well the cartridge filters used on these engines can collapse and block oil flow! The paper element must be treated to "wet" on contact with oil or it may take time for the oil to flow through it correctly. I have had cheap brake pads de-laminate from the backing plate and the steel backing plate rubs on the disc.

There are good known-brands in the after market area but typically the price is proportional to the quality.

I trawl shopping sites such as Ebay and Gumtree for bargains and stock up before I need them. You can get top brands for bargain prices...or at least within your budget.

For some items, it is just as cheap to buy from Citroen. Then you can be sure of quality. However, there are many filters on ebay which claim to be genuine Citroen filters, and I certainly wouldn't take a chance on them, particularly oil filters. It just isn't worth it.

No disrespect intended to routemaster1 for any of the following, just more for the readers to consider.

There is an old Latin saying. Caveat emptor; buyer beware.

"knock offs" can pervade every area of the retail market and they can be very good (looking) forgeries. Having said that, it is unlikely parts bought through the franchise outlets are anything but genuine. However buying from a "bricks and mortar" store might not be convenient...and so we are back to Caveat emptor.

Here in Australia buying parts from Citroen is HIDEOUSLY EXPENSIVE!!!!!! I bought innocuous parts (like oil filters and washers) for my C2 from the UK and shipped them here before the aftermarket...er...market caught up, rather than buy them from the franchise here and it was still cheaper. I get sellers from the UK balking at the cost of postage, claiming "it's too expensive". Do you have a @#$%ing clue how rare and expensive stuff can get here? Sorry, I'm getting over excited. LOL!

I just bought a Gates timing belt and water pump kit from the UK for a price little more than the cost of the water pump alone here. So buying online can save you a lot of money. Did I get the genuine article? If I bought it from a bricks and mortar store would it have been genuine? Caveat emptor.

I have found there are some after-market components which are actually superior to the OEM product. For example shock absorbers. Companies such as Bilstien, KYB and Monroe are superior and cheaper than the OEM offering. Springs, on the other hand are the opposite. The front springs on the C3 are very unusual, in that they are curved and barreled. I believe [that while they fit] most of the aftermarket units are not suitable and I would have to do some serious homework to find anything suitable except OEM as a replacement.

Then there are parts which are only made by a handful of manufacturers, like spark plugs. Citroen use Bosch plugs and you can buy them virtually anywhere.

However routmaster1 is right. On occasion, the OEM part from the franchise can be found at a competitive price. Give them a ring, you have nothing to loose, after all the cost of a phone call is virtually free these days.

No offence taken. The comment about buying from Citroen really applies to the European market, and it is not often apparent that things are very different elsewhere. It is important for some components to be of guaranteed quality, the issue sometimes is knowing which brands are reliable and which are not. When i first had a Citroen and joined forums there were many issues with oil pressure failures due to pattern filters failing, and advice then was to go with Citroen. Maybe not so important with air filters and wiper blades.

Yes, the Purflux oil filter debacle, it's what I eluded to in my post.

I guess after market manufactures have to gain your confidence. Then there items within their catalogue that you just wouldn't buy, because another manufacturer does it better. I can see how people get confused.
