5 Inch Spark Arrestor Disc, Sold Each

OVERVIEW

When you''re tearing up the dunes or navigating tight forest trails in your air-cooled VW, maintaining the perfect balance between engine performance and environmental safety is paramount. The Latest Rage 5-Inch Spark Arrestor Disc is a precision-engineered component designed to give you total control over your exhaust system''s flow and sound. Crafted from high-grade stainless steel, these discs are built to withstand the extreme heat and corrosive gases produced by high-performance Volkswagen engines. Whether you are running a classic Beetle, a rugged Baja Bug, or a dedicated sand rail, these discs allow for fine-tuning your backpressure to optimize horsepower and torque curves. By adding or removing discs, you can effectively "tune" your exhaust note and flow characteristics, ensuring your engine breathes exactly the way it needs to for your specific driving conditions.

Beyond performance tuning, these 5-inch discs serve a critical role in trail safety and legal compliance. Many off-road parks and National Forest lands require a USFS-approved spark arrestor to prevent hot carbon particles from exiting the tailpipe and potentially starting a fire. These replacement or expansion discs fit perfectly into standard 5-inch canister-style spark arrestors, providing the necessary diffusion to trap dangerous sparks without excessively choking your engine. Because they are sold individually, you have the flexibility to replace a single warped disc or completely overhaul your stack to meet the decibel requirements of your local riding area. At Appletree Automotive, we know that every air-cooled setup is unique, and these stainless steel discs provide the modularity required by professional builders and weekend warriors alike.

FITMENT

This 5-inch spark arrestor disc is designed for universal application on 5-inch canister-style exhaust systems commonly found on the following air-cooled VW models and custom builds:

• Volkswagen Beetle (All Years): Ideal for custom high-mount or "stinger" style exhausts with spark arrestor ends.
• Volkswagen Karmann Ghia: Fits custom performance exhaust systems requiring spark suppression.
• Volkswagen Bus (Type 2): Used in off-road oriented Transporter builds and campers.
• Volkswagen Type 3 (Squareback/Fastback): Applicable for custom performance exhaust modifications.
• Dune Buggies & Sand Rails: A standard requirement for Meyers Manx, Berrien, and custom tube-chassis rails.
• Baja Bugs: Essential for off-road endurance and trail-riding compliance.
• Custom VW Trikes: Fits 5-inch collector-style mufflers.

PRO TIPS

PRO TIP 1: Master the Art of Tuning. The number of discs you run directly impacts your engine''s performance. Generally, adding more discs increases the exhaust flow area, which reduces backpressure and increases top-end horsepower but also increases noise. Conversely, removing discs increases backpressure, which can help with low-end torque and quiets the exhaust note. If you are struggling with a "flat spot" in your acceleration, try adding or removing three discs at a time to see how your VW engine responds on the dyno or the trail.

PRO TIP 2: Never Forget the Anti-Seize. When assembling your spark arrestor stack, always apply a high-temperature nickel or copper-based anti-seize lubricant to the bolts holding the discs in place. The extreme heat cycles of an air-cooled exhaust can cause stainless steel hardware to gall or seize over time. By using anti-seize, you ensure that you can easily take the stack apart later for cleaning or tuning without snapping a bolt off in your collector.

PRO TIP 3: Keep It Clean for Peak Flow. Over time, carbon deposits and unburnt oil (especially in older or richer-running engines) can clog the fine gaps between the discs. This restriction can cause your engine to run hot and lose power. We recommend removing the discs at least once a season and giving them a quick scrub with a wire brush or soaking them in a carbon-dissolving solvent. Clean discs ensure that your spark arrestor remains effective and your engine stays cool.
