The EBC UD1089 is a front disc brake pad set from EBC's Ultimax2 line, sold for the 2007-2009 Acura RDX 2.3 Turbo. It is meant as a direct replacement for the front pads on that model, so you can restore the front braking setup without changing other components. Search terms that match this part include UD1089 front pads, EBC Ultimax2 2.3 Turbo RDX, and 07-09 RDX turbo front brake pad replacement.
Choosing this set over a generic budget pad makes most sense when you want a part tied to a named application for this exact turbocharged RDX rather than a universal fit. Confirm the year and engine match against your VIN before ordering, because application ranges for this pad vary between listings and the manufacturer's catalog is the reliable reference. Buying a matched front pad also keeps the front axle consistent with the rotors you already run, which matters if you plan to pair pads with a rotor upgrade later.
