Man, those KTIs are pricey! Wow, but they sure do look nice.
The racor dual setups run around 800-900 dollars. The ones we bought from Griffin are 500 bucks and look like they're just a rebranded racor. The filters are actually identical as Griffin makes the racor filters.
Another plus side of getting the turbine setup filters is that changing the fuel filter costs approx 10 bucks, instead of like 50+. And changing them is very easy.
Jack, I know it might be extra money you don't want to spend, we certainly didn't want to sink that extra money into the filters when we were redoing everything, but now that they are there... I'd do it again. Its clean, easy, and fool proof.
