UMS 210cc Baffle

$45.00

Precision-cut plywood baffle sized specifically for the UMS 210cc 5-cylinder engine. The baffle channels cooling airflow directly over the cylinder heads inside the cowl, preventing hot air recirculation that raises cylinder head temperatures and reduces engine reliability. Without a correctly fitted baffle, incoming ram air bypasses the cylinder fins and thermal management deteriorates rapidly during sustained high-power flight. Compatible with: 5-210CC.

SKU: UMS-BAF55-9 Category: UMS BAFFLE Tag: 5-210CC

Plywood baffle precision-cut to the cylinder layout and cowl geometry of the UMS 210cc 5-cylinder engine. The baffle acts as a physical divider inside the cowl, forcing incoming ram air to flow directly over and between the cylinder heads and cooling fins rather than taking the path of least resistance through open cowl space. Effective cowl baffling is one of the most important factors in maintaining consistent cylinder head temperatures — an unbaffled or poorly fitted cowl allows hot air to recirculate around the cylinders, creating localized hot spots that accelerate wear on valve guides, piston rings, and cylinder bore surfaces. This baffle is cut specifically for the 210cc variant and its cylinder spacing — it is not interchangeable with baffles for other engine sizes even within the same UMS engine family. Install with the cut edges flush to the cowl interior surfaces, with no gaps at the cylinder head fins that would allow air to bypass the baffle.
