I have always used Mahle oil filters until they became unavailable northside. So I switched to Mann as they are available locally MW 712 $21.61 ea. You do have to order them in advance in order to get them at that price. To save on freight costs they bulk order every couple of months. The next shipment is 2-3 weeks away so I ordered two, when I do fit the last one I'll order another two. I did have one in stock but two five litre bottles of distilled water one full one with about a litre in it sprung a leak totally destroying my spare. The bottle plastic has deteriorated to the point where you can just about poke your finger through it. They were approximately 18 months old.
