Briggs & Stratton Pre Cleaner - 493537S (5 Pack - 4147)

Product Details & Features

Keep your Briggs & Stratton engine breathing cleaner and performing better with this 5‑pack of genuine pre‑cleaners (Part 493537S) — an essential accessory for extending the life and efficiency of your air filtration system. Designed to work with compatible engines and the corresponding main air filter, this set helps reduce dirt ingestion and prolong filter life. 

This 493537S pre‑cleaner kit features flat‑panel foam elements that fit over the primary air filter on select Briggs & Stratton 3.5 HP–6.5 HP Quantum engines and similar applications. It captures larger dust, grass clippings and debris before they reach the main air filter, helping to maintain proper airflow and protect the engine from premature wear. Sold as a 5‑pack (Part 4147), it’s ideal for servicing multiple machines or keeping spares on hand. 

Key Features:

• Genuine OEM Quality: Manufactured to Briggs & Stratton’s original specifications for proper fit and performance. 

• Enhanced Engine Protection: Foam pre‑cleaners trap larger particles before the main filter, reducing contamination and extending engine life. 

• Extended Main Filter Life: By capturing coarse dirt and debris first, these pre‑cleaners help reduce clogging of the primary air filter. 

• 5‑Pack Value: Comes with five pre‑cleaner elements — perfect for multiple routine services or stocking up for future maintenance. 

• Easy to Fit: Simple foam installation slips over the air cleaner for quick replacement without tools. 

Why It Matters:
Airborne grit and debris can accelerate engine wear and reduce performance. Installing these genuine 493537S pre‑cleaners helps keep your main air filter cleaner for longer, promotes better airflow and contributes to smoother starts, steadier idling and longer engine life — especially when working in dusty or heavy‑use conditions. 

Perfect for routine maintenance, small engine servicing, or preparing equipment for peak mowing season!
