Spark Arrestor, 10 Stainless Steel with Side Mount

EMPI 10-Inch Stainless Steel Spark Arrestor with Side Mount

VW Fitment and Compatibility

This EMPI spark arrestor (Part # 00-3737-0) is a premium exhaust solution designed specifically for air-cooled VW off-road applications. It features a 2-inch inlet designed to clamp onto 2-inch O.D. exhaust systems. This unit is the most popular choice for Tri-Mill Bobcat style exhausts and is commonly used on Dune Buggies, Sand Rails, and Baja Bugs. The 10-inch stainless steel body provides excellent durability against the elements, while the 4-inch baffles ensure proper flow and spark suppression.

Pro Tech Tips for Installation and Maintenance

Verify USFS Compliance for Trail Riding: Most public lands and off-road parks require a functional spark arrestor to prevent wildfires. Before heading out, ensure your arrestor is securely mounted and free of holes. This EMPI unit is designed to meet these safety standards, making your VW-powered rig legal for forest service roads and dunes.

Prevent Power Loss with Regular Cleaning: Carbon deposits can build up within the 4-inch baffles over time, which increases backpressure and can cause your engine to run hot or lose top-end power. Periodically remove the spark arrestor and tap out any trapped carbon or use a solvent cleaner to keep the internal screens clear and your air-cooled engine breathing efficiently.

Use Heavy-Duty T-Bolt Clamps: Because this is a side-mount clamp-on unit used in high-vibration off-road environments, standard worm-gear clamps may loosen over time. For the most secure fitment on your 2-inch header, upgrade to a stainless steel T-bolt clamp. This provides more even clamping pressure and ensures the arrestor stays attached even during hard landings or rough washboard terrain.
