Good pleat count
Went on my A6 C7 1.8 TFSI at 166k miles. The pleat count is visibly higher than the supermarket filter I had been using. It dropped straight into the housing and the cap torqued to spec first go. Result is throttle response feels crisper than it did on the clogged original.

Genuine quality for less
Ordered this for my A4 B8 after the original gave up at 131k. I pre-oiled the seal before fitting and there has not been a drop since. The pleat count is visibly higher than the supermarket filter I had been using. 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 (A5 8T)
Went on my A5 8T 2.5 TFSI at 125k miles. Two minutes behind the glovebox once I had the tabs released. Dimensions matched the outgoing filter to the millimetre. Result is throttle response feels crisper than it did on the clogged original. No complaints at all.

No leaks, no fuss
Ordered this for my A3 8P after the original gave up at 162k. 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 oil pressure comes up as quickly on a cold start as it always has. Happy to recommend it.

Fine filter, seal was dry
Went on my Q5 8R 2.0 TFSI at 139k miles. Two minutes behind the glovebox once I had the tabs released. The gasket was dry and flat out of the packet and would not seat cleanly. That said, no leaks at all after several hundred miles. Would still buy it again.

Correct fit, sealed properly
Replacement for my 2010 Q5 8R 1.4 TFSI. 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 shifts are smoother now the transmission has clean fluid and a fresh filter.

Exactly what the service needed
Went on my Q5 8R 2.0 TDI at 84k miles. 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. Will be back for the other side.

Right filter every time
Bought for a 2022 Q8 4M. The media feels dense and the end caps are properly bonded rather than glued on thin. It dropped straight into the housing and the cap torqued to spec first go. Result is shifts are smoother now the transmission has clean fluid and a fresh filter.
