thank you everyone for your input, they have been very helpful.
the reason I want to replace the filter is because they are in the fender and I have no idea how to take it out and clean it. I am sure it is serviceable as I think it is a K&N wet filter, but I dont have the tools or confidence in taking it out.
You think I should just replace the cat?
hrm, I am pretty sure the 100k service has been done as my mechanic told me the timing belt doesn't look worn. reason I am worried is i just don't know what the previous owners did. Also I have difficulties shifting into second gear from third and the car shudder alot at very low speed.
