Radium 20-0811 10AN Press-In Exhaust Valve Cover Fitting for Nissan S13 SR20DET

Vehicle Fitment

• 1989-1994 Nissan Silvia (S13, SR20DET 2.0L Turbo I4, RWD)
• 1989-1994 Nissan 180SX / 200SX (S13, SR20DET 2.0L Turbo I4, RWD)

Fitment Notes

• Fits the exhaust side valve cover barb only on the S13 SR20DET - this is a double-ended banjo design specific to the S13 exhaust valve cover port
• Not compatible with the S14 or S15 SR20DET exhaust side valve cover - see Radium 20-0812 for S14/S15 exhaust side fitment
• For the SR20DET S14/S15 intake side PCV valve port, use Radium 20-0808
• When installed in place of a CCV or breather valve, a PCV valve must be installed inline or on the catch can as needed to maintain proper crankcase pressure regulation

Features

• Double-ended banjo design is a direct replacement for the exhaust side valve cover barb unique to the S13 SR20DET
• Converts the factory exhaust side press-in port to a 10AN male swivel connection for catch can breather lines
• Low-profile design minimizes installed height for tight S13 engine bay clearance
• 360° swivel action with FKM O-rings for flexible hose routing after installation
• No drilling or welding required - direct press-fit installation
• Stainless steel and anodized aluminum construction with laser-engraved Radium branding

Product Description

The Radium Engineering 20-0811 is a 10AN double-ended banjo press-in swivel fitting designed as a direct replacement for the exhaust side crankcase vent barb on the S13 Nissan Silvia and 180SX SR20DET valve cover. Its double-ended banjo configuration matches the unique port geometry of the S13 exhaust valve cover, converting it to a 10AN male swivel connection for large-diameter breather lines used in catch can and air/oil separator setups. No drilling or permanent modification is required.

The 360° swivel allows the hose outlet to be oriented in any direction after installation for clean, routed catch can plumbing. FKM Viton O-rings ensure long-term chemical resistance to oil vapors. Builders should note this fitting is exclusive to the S13 exhaust side port - the S14/S15 SR20DET uses a different exhaust side fitting (Radium 20-0812), and the S14/S15 intake PCV port uses Radium 20-0808.
