Good pleat count
Bought for a 2020 A5 F5. Dimensions matched the outgoing filter to the millimetre. The old one practically fell apart coming out; this went in cleanly. Result is shifts are smoother now the transmission has clean fluid and a fresh filter. Will be back for the other side.

Fine filter, seal was dry
Fitted to my 2015 Q3 8U. I changed it with the oil at the same service interval. The media feels dense and the end caps are properly bonded rather than glued on thin. On balance shifts are smoother now the transmission has clean fluid and a fresh filter. Would still buy it again.

Genuine quality for less
Replacement for my 2009 Q7 4L 2.0 TDI. The old one practically fell apart coming out; this went in cleanly. The pleat count is visibly higher than the supermarket filter I had been using. Result is shifts are smoother now the transmission has clean fluid and a fresh filter.

Good value, thin gasket
Cross-referenced the OE number against my 2014 Q3 8U before ordering. I changed it with the oil at the same service interval. The pleat count is visibly higher than the supermarket filter I had been using. On balance throttle response feels crisper than it did on the clogged original. Would still buy it again.

Correct fit, sealed properly
Second one of these I have bought, this time for the A7 4G. I pre-oiled the seal before fitting and there has not been a drop since. Dimensions matched the outgoing filter to the millimetre. Result is throttle response feels crisper than it did on the clogged original.

Right filter every time
Went on my Q5 8R 1.8 TFSI at 91k miles. Dimensions matched the outgoing filter to the millimetre. I pre-oiled the seal before fitting and there has not been a drop since. Result is shifts are smoother now the transmission has clean fluid and a fresh filter. No complaints at all.
