Peugeot 404 - Notes on the Air Filter

The air filter, its boring and not very complicated, right ? Well, I wanted to change the filter and when the car-parts guy started asking questions I found out that the 404 has at least two different possible air filter systems (dry or 'wet') and each one has more than two different setups. Here is a short description and my final work-around when I received a filter that was just too short.

Dry air filter

These images show two mountings for dry air filters on the Peugeot 404.

The Peugeot part numbers for the possible dry air filters are :

1445.10 (Laurette L745 or L697) for carburator mounted cars (second drawing above)
1445.11 (Laurette L965) for the injection engine mounted cars
1445.23 (Laurette L1276) - injection, after 1967
1445.30 (Laurette L1275 or 1274) - carburator, up to year ??
1445.50 (Laurette L1621) - carburator, from year ??
1445.39 for the 404U6S and 404U6S automatic

Work around

The size of the filter for my 404 is 108 mm (diameter) by 170 mm (length). This is easy to measure ; just stick a ruler in the filter holder. I received a shorter filter (140 mm) which probably corresponds to the later installation. To use this filter, the easiest fix was to cut a 50 mm length of filter from a cheap, spongy air filter of the same diameter and use that as supplementary support.
