Briwooody air filter kit for Stihl TS410 TS420 series — 8-pack with pre-cleaners, pleated paper & rubber seal

Briwooody replacement air filters with matching pre-cleaners for Stihl TS410/TS420 series deliver reliable dust exclusion to protect your concrete saw’s engine and help preserve peak performance.

These Briwooody kits include eight primary air filters and eight pre-cleaners designed to fit a range of Stihl cut-off saw models (TS410, TS420, TS410z, TS420z, TS480, TS500i) and the common part numbers listed for these units. Each filter combines durable rubber framing with pleated filter paper to trap abrasive dust and debris generated during masonry and concrete cutting. The pack gives you several service intervals’ worth of parts so you can perform scheduled maintenance without downtime.

Will these filters fit my Stihl concrete saw?

Check compatibility by matching your saw model or the OEM part numbers. The Briwooody TS410/TS420 filter set corresponds to the Stihl part references (4238-140-1800, 4238-141-0300, 4238-140-4401 through 4404) and fits the listed TS series saws when the stock filter geometry matches.

• Fits models: TS410, TS420, TS410z, TS420z, TS480, TS500i
• OEM cross-references included for quick verification
• Measure approx. 5-1/2" wide × 5-3/4" long × 1-3/4" high to confirm fit
• Confirm your engine cover footprint before ordering to avoid mismatch

How do these air filters improve saw maintenance and uptime?

Using fresh primary filters and pre-cleaners reduces abrasive dust ingestion, which can accelerate wear on cylinder ports, piston rings, and carburetor parts. Replacing both the pre-cleaner and main filter on a schedule lowers the chance of clogged filters and keeps intake airflow consistent, supporting smoother starts and more predictable power delivery.

• Includes eight filters and eight pre-filters for multiple maintenance cycles
• Pleated paper media traps fine particles; rubber frame creates a tight seal
• Swapping the set is quick, minimizing downtime at the jobsite
• Regular replacement prolongs engine component life by reducing abrasive ingress

What materials and build quality should I expect?

Each Briwooody air filter pairs a resilient rubber outer frame with folded filter paper engineered for dusty construction environments. The components are made for durability under vibration and frequent handling, and the pre-cleaner adds a first line of defense that captures larger debris before it reaches the pleated media.

• Rubber frame for a secure gasket seal and vibration resistance
• Pleated filter paper for increased filtration surface area
• Pre-cleaner traps coarse dust, extending the life of the main filter
• Designed for easy, tool-free replacement in most stock housings

How easy is installation and what dimensions should I check?

Installation is straightforward: remove the engine cover, take out the old pre-cleaner and filter, and insert the new pre-cleaner followed by the primary filter, ensuring the rubber edge seats evenly. The approximate dimensions—5-1/2" width × 5-3/4" length × 1-3/4" height—help confirm the correct fit for your intake housing.

• Tool-free access on most Stihl TS housings—follow your operator manual
• Confirm dimensions against your existing filter before purchase
• Replace both pre-cleaner and main filter at the same time for best results
• Eight-filter quantity supports scheduled maintenance without repeat orders

Who is this for? The Briwooody TS410/TS420 8-pack is intended for contractors, rental-house operators, and serious DIYers who run Stihl concrete cut-off saws in abrasive environments and prefer keeping spare filters on hand. If you perform frequent masonry cutting or operate saws on dusty sites, this bulk set reduces service interruptions and simplifies routine maintenance. Always verify your saw’s model and filter footprint before ordering to ensure compatibility.
