Exactly what the service needed (Q5 8R)
Replacement for my 2011 Q5 8R 2.0 TFSI. The media feels dense and the end caps are properly bonded rather than glued on thin. I changed it with the oil at the same service interval. Result is the musty smell from the vents has completely gone.

Good pleat count
Bought for a 2009 Q5 8R. Dimensions matched the outgoing filter to the millimetre. The old one practically fell apart coming out; this went in cleanly. Result is throttle response feels crisper than it did on the clogged original. Will be back for the other side.

Correct fit, sealed properly
Second one of these I have bought, this time for the RS4 B7. Dimensions matched the outgoing filter to the millimetre. It dropped straight into the housing and the cap torqued to spec first go. Result is no leaks at all after several hundred miles.

Right filter every time
Cross-referenced the OE number against my 2013 Q7 4L before ordering. 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 oil pressure comes up as quickly on a cold start as it always has.

No leaks, no fuss
Second one of these I have bought, this time for the TT 8J. I changed it with the oil at the same service interval. Dimensions matched the outgoing filter to the millimetre. Result is the musty smell from the vents has completely gone.

Genuine quality for less
Went on my A7 4G 2.0 TFSI at 168k miles. The rubber seal is supple and sat in its groove without coaxing. I pre-oiled the seal before fitting and there has not been a drop since. Result is oil pressure comes up as quickly on a cold start as it always has. No complaints at all.

Exactly what the service needed
Ordered this for my Q5 8R after the original gave up at 119k. 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 shifts are smoother now the transmission has clean fluid and a fresh filter.
