You should spend a whole day finding the best deal on the most obscure off brand filter made in China or prehaps a floating barge off the coast of Sri Lanka. Hopefully they will use only the finest ground waterbuffalo dung as filter media. Or,stop by your local Cat dealer and get the right filters that are built by the same people who designed and built the engine in the first place. I have seen many people think they are saving huge amounts of money buying will-fit filters. The proof is in oil sampling, Cat filters will produce cleaner samples. Run a 1R-1807 oil filter, see for yourself how cleanyour oil stays. I doubt you are going to put 50,000 miles a year on, so how much are you actualy going to save. Yes, I may be biased. But, I have seen this all first hand and have nothing to gain or loose.
