Viton O-Ring Set - Throttle Body Elbow (FD3S, Cosmo) [Single]

Single Throttle Body Elbow O-Ring for the Series 6 RX-7 and 90-95 Cosmo.

Being a Viton material allows these O-rings to be reused with confidence and are resilient against a wide range of chemicals including engine oil, alcohol, methanol, and ethanol.

Most OEM and aftermarket replacement O-rings are made of Buna-N (Nitrile Rubber) which deform over time due to normal heat-cycling of the engine. This can become a problem as they will start to lose sealing ability and can lead to boost leaks or complete failure.
