We sell plenty of OEM parts like the Ring Piston Seal above. We believe Genuine OEM parts are the only parts and accessories drivers should be using to maintain the quality and health of their vehicles. They last longer than aftermarket parts and fit specifically into or onto your vehicle. 

We offer the entire Acura OEM Parts Catalog so if this part is not the one that fits your vehicle, you can Search For Parts By Selecting Your Acura Model as well.
