Oil filter
An interesting bit of background reading (to be taken at face value) before rushing out and buying the cheapest filter! Apparently, the filter is common to all 4 cylinder Hondas from 1985 - 2007 (not confirmed) so sourcing one shouldn't be a problem. Some reported equivalents are as follows:
OEM
Crosland oil filter number 672
This filter is currently (2009) being supplied by Lotus.
