Right filter, tight in the housing
Fitted to my 2009 A3 8P. The old one practically fell apart coming out; this went in cleanly. The outer diameter was a couple of millimetres off and it would not sit square in the housing. That said, oil pressure comes up as quickly on a cold start as it always has. Worth buying, just go in with your eyes open.

Right filter, tight in the housing (A4 B7)
Went on my A4 B7 2.5 TFSI at 69k miles. Two minutes behind the glovebox once I had the tabs released. The outer diameter was a couple of millimetres off and it would not sit square in the housing. That said, no leaks at all after several hundred miles. Would still buy it again.

Good pleat count
Ordered this for my Q5 8R after the original gave up at 132k. The pleat count is visibly higher than the supermarket filter I had been using. Two minutes behind the glovebox once I had the tabs released. Result is shifts are smoother now the transmission has clean fluid and a fresh filter.

Right filter every time
Second one of these I have bought, this time for the A5 F5. I pre-oiled the seal before fitting and there has not been a drop since. The rubber seal is supple and sat in its groove without coaxing. Result is no leaks at all after several hundred miles.

Correct fit, sealed properly
Bought for a 2022 Q8 4M. I pre-oiled the seal before fitting and there has not been a drop since. The rubber seal is supple and sat in its groove without coaxing. Result is throttle response feels crisper than it did on the clogged original. Would order again without hesitation.
