hi folks, im hoping for some advice re filters. betty has just failed her mot on a couple of bits

which hopefully will be sorted on tuesday and my hubby is thinking that we should replace the filters as well soon

- oil, fuel and air i think he said. had a quick peek on ebay and theres tons but some are square and flat and some are like a cylinder, so bit confused really

. can anyone recommend any or post links to ones theyve bought and found to be ok. there are some where you get the 3 as a set but again - which ones would be best.
shes a n reg - is that a 97? 2.5td 4wd.
thanks in advance
