Which component is designed to seal gaps in the cowling to prevent air leakage?

• A. Cowl air seals
• B. Blast tubes
• C. Water jackets
• D. Spark plug wires

Answer: (A)

Sealing gaps around the engine cowling directs the cooling air along the intended path through the cylinder fins and baffles. Cowl air seals fill the gaps between the engine and the cowling, preventing high-pressure cooling air from leaking out of the cowl. This keeps the airflowFocused through the cooling passages, improving cooling efficiency and reducing drag from leaks. The other items serve different roles—blast tubes relate to air routing elsewhere, water jackets are part of the cooling system around the cylinders, and spark plug wires carry ignition energy—none are intended to seal the cowling gaps.
