STIHL 1130 141 9003 Spark Arrestor Screen | 017, 018, MS 170 & MS 180

STIHL 1130 141 9003 OEM Spark Arrestor Screen

The STIHL 1130 141 9003 Spark Arrestor Screen is a genuine OEM replacement muffler screen used on select STIHL 017, 018, MS 170, and MS 180 chainsaws. This part is listed as Screen and is commonly searched as a spark arrestor screen, muffler screen, fire screen, exhaust screen, or chainsaw spark screen.

Spark arrestor screens help reduce the chance of hot exhaust particles exiting the muffler during operation. Over time, these screens can become clogged with carbon, restricted from oil buildup, rusted from heat, or damaged during use. A plugged spark arrestor screen can cause poor throttle response, loss of power, rough running, hard starting, or poor exhaust flow.

Always verify your exact STIHL model, serial number, version, muffler style, original part number, and parts diagram before ordering. Do not order by chainsaw family alone.

Why Replace the Spark Arrestor Screen?

The spark arrestor screen is one of the most common small exhaust parts to wear, plug, or rust out on a chainsaw muffler. Carbon buildup can restrict exhaust flow, while heat and moisture can eventually weaken or corrode the screen.

Replacing a clogged or damaged screen can help restore proper exhaust flow and keep the muffler system working as intended. When your STIHL parts diagram lists 1130 141 9003, this OEM screen is the correct replacement for that application.

• Helps maintain proper muffler exhaust flow
• Helps prevent carbon restriction problems
• Maintains the original spark arrestor setup where required
• Correct OEM fit when specified by STIHL
• Reduces guesswork compared to universal replacement screens

When to Replace a Spark Arrestor Screen

Replace or inspect the muffler screen if the chainsaw loses power, will not rev out, runs rough, has poor throttle response, or if the screen is visibly clogged, rusty, burnt, torn, or missing.

• Chainsaw loses power under load

• Allow the muffler to cool completely before service
• Disconnect the spark plug boot before working on the saw
• Inspect the existing screen for carbon buildup, rust, or tearing
• Clean carbon from the muffler outlet area as needed
• Inspect screws, outlet cover, muffler body, and exhaust gasket
