Review on Mann Filter 940 25 Spin Filter by Robert Tirona

These larger capacity filters are perfect for VW AUDI 1.8T to prevent the infamous oil sludge problem and for 2, 2L I5 Turbo to increase capacity and reduce engine temperature. I've fitted them to several cars I own and can't say anything bad about them. The only reason I'm not rating 5 stars is because I wish they would make modifications to include a check valve. The angle it sits on my A4 is impossible when taken off. I usually put a plastic bag around and under the filter to contain the leak when it hits the subframe, but this is tricky. Great product, does what it's supposed to.
