Not right Barn, the filter can be bought from different outlets, you just have to search, the thing with a petrol 4cx4 it's heavy, pulls a lot of weight around 15cwt up to a ton, providing you use ( In my opinion) good fuel, what I mean by that, not supermarket fuel ( but each to their own choice) have the filters changed at the correct time ( Service) myself, I always drop the oils / filters every 5000, but that's my choice, I'm not made of money but it's cheaper changing the oil than changing the engine, If you purchase a 4x4 make sure it has history & stamped, if the belt if has been changed, If you are not good with Mechics get someone to go with you, you get trouble with 4x4s you are talking about big money, if unsure, walk away, be aware of "side of the road dealers" there is to a point, no comeback, have a look at supermarket notice boards, ebay, or any site that deal with 4x4 only.
