Hi Paul,
By coincidence, I've just finished servicing my wife's (new to her) 2005 1.4SE (57,000 miles) this morning and found it reasonably straightforward. I bought all my parts on eBay (Genuine Honda) but I could have done it much cheaper using parts from the local motorists' shop.
Honda air filter (made in Japan), 8x Honda plugs (NGK made in France), Honda oil filter (Puro Brand made in France) , sump plug washer and Honda pollen filter (made in Germany) set me back £64 in total. Add to that £33 for 5L Millers XFS 5w-40 (fully synthetic) oil and the parts total was £97. (I wanted a quality oil that I can use in both the Jazz and my Astra convertible and this was the one recommended on Millers' web site. I'm sure a cheaper oil would have been OK.)
I had a bit of trouble getting access to the sump plug and ended up running the car onto ramps. It is then easy (you will need a 17mm socket). I now know why people say the Jazz handbrake is poor and could smell a hot clutch plate as I revved to get onto the ramps. The oil filter is dead easy with the front raised but you will need a strap or chain wrench to remove the old one. Mine was very tight and took some shifting.
My air filter is the newer, square one so it's just a matter of flipping off four clips to remove the cover and then replacing. The filter was thickly encrusted with black grease and debris so it's a wonder the car was running so well although it was a bit 'breathless' on the motorway.
The plugs are a bit tricky so far as access is concerned and you will need a long, thin-walled 16mm spark plug socket with a rubber insert to grip the plugs plus a short extension and ratchet socket wrench. I removed the coils and plugs and fitted the new plugs one at a time. I did the front bank first to get the hang of it before tackling the rear bank. The 10mm bolts that fix the coils were very tight. Be sure to use some copper grease on the plug threads and screw them in by hand before tightening, preferably with a torque wrench. Mine only goes down to 15 lb ft so that's what I used. You'll need to release the rear plug wiring loom from its clips. I also removed two rubber pipes from the inlet manifold to give me room to swing the ratchet. The plugs that I took out were well worn with .050" gaps.
The pollen filter couldn't be easier - just pull out the glove box insert, free the two clips on the white tray revealed and pull the filter housing out. Make sure the air flow direction is correct when replacing.
I took my time doing the service and cleaned everything before replacing it. Including a trip to the local shop to buy copper grease and a long spark plug socket it took about four hours but next time it should be much quicker and easier.
The car certainly seems to be running more sweetly for all this TLC. I also poured a bottle of injector cleaner into the tank as it can't do any harm.
I hope all this helps. The Haynes manual (£14 from eBay) is a wise investment.
Best of luck,
Brian
