YS Engine YSF8089 DZ170 Tube Retainer - Replacement Part  [YSF8089]

Durability and Fit for DZ170 Headers

Designed as an RC spare, this tube holder secures exhaust tubing on DZ170-series model engines to limit movement and maintain routing integrity during extended runs and service. It provides a reliable retention point between header and muffler without affecting other engine components.

Fitting focuses on correct alignment and secure clamping rather than altering performance: route the pipe through the holder, align to the engine exhaust outlet and mounting points, then fasten with existing screws or clamps. Because it matches common DZ170 mounting geometry, inspect fit before permanent fixing.

Keeping the exhaust path consistent helps repeatable tuning and testing; the holder reduces shifts that can change backpressure or pipe direction. Treat it as a maintenance aid when changing mufflers, tweaking pipe angle, or preparing the engine for bench or on-track checks.
