Just installed this kit today, took around an hour. I did it while flushing my cooling system, so while it was draining, I was installing. Super easy to install, all you need is in the kit except you may want some Teflon tape or paste. Only tools you need are basic hand tools. Only reason for the four star rating is the instructions included (from BD Power, not BC Diesel) were a little hard to see the black and white pictures, but if you go to their website you can download it in PDF with full colour. Can't wait to see how much crap the filter keeps out of my engine!
As far as the service, I ordered this filter kit on a Thursday night, got an email saying it shipped Friday morning, and had it delivered Monday afternoon. With free shipping I certainly wasn't expecting it that quickly, but I sure was happy!
