THE BIT THEY DIDN'T PUT ON THE BOX.
Two badges. One V10-shaped question.
The exact same physical V10 air filters fit both cars. Sourced under the Lamborghini part number, they retail for around £90–£120 each. Sourced under the Audi R8 cross-reference, the identical part drops to roughly £30–£45.
SO WHAT'S THE CATCH?
Check the full filter reference and revision for the specific car.
