Dear Members. Doing basic checks on car, Looked at air filter, soiled and oiled. Reffered to Haynes Manual for filter spec, It told me Champion W229. Names and numbers always seem to tell me that i have to buy that specific make. So went to Halfords thinking if anywhere, i'm going to get one from their. Afraid not, they have their own brand of filter which does not include an equivalent to the above named. I'm stuck, Do any of you know of a shop supplying parts for our car and if so doe's anybody know what type/serial no- i can use, after all , its an air filter. Thanks Mike.
