Look under GREY/SILVER: EZR is Aluminium
2. After market oil filters have been known to collapse causing low oil pressure so I always buy a genuine filter.
3. The air filter is fairly easy to change but do ensure that you get the housing together correctly and tight. I always buy the OE filter because it fits perfectly and, changed every 40,000 miles is not expensive. An incorrectly fitted housing cover can let wet in during rainy weather and can soak the element in water. Renders it useless and will stop the car running.
4. Mine don't squeal but it is still on the original discs and pads.
5. Again my tyres are still original and the car drives and handles well on that size. Important to use quality tyres. Mine is on Continentals.
6. Never used them. I bought a space saver spare off eBay. Used it once when I had a flat.

http://www.peugeot206cc.co.uk/viewtopic ... 8&p=123250 I use genuine Duracell or Energizer CR2016. Make sure that you do not touch the battery with your fingers when fitting ... I get mine off an eBay seller - gogreenuk. Have used them often, good quality, good prices and quick delivery.
