Spark Arrestor Bolts, Stainless Steel, 6 Pack

EMPI Stainless Steel Spark Arrestor Bolts - 6 Pack

Product Overview and Fitment

This 6-pack of EMPI stainless steel bolts (Part #00-3740-0) is the essential replacement hardware for disc-style spark arrestors. Constructed from high-quality stainless steel, these bolts are designed to withstand the harsh environments and extreme heat associated with aircooled VW exhaust systems. They are compatible with most standard spark arrestors found on Dune Buggies, Sand Rails, Baja Beetles, and other off-road Volkswagen applications.

Pro Tech Tips

Tip 1: Apply Anti-Seize Compound. We highly recommend applying a small amount of high-temperature anti-seize to the threads before installation. Stainless steel hardware is prone to "galling" or seizing when exposed to the intense heat of an exhaust system. Using anti-seize ensures you can remove the bolts easily in the future to clean your spark arrestor or adjust the number of discs.

Tip 2: Use Even Tension. When installing these bolts into your spark arrestor stack, tighten them in a cross-pattern (similar to tightening lug nuts). This ensures that the pressure is distributed evenly across the discs, preventing exhaust leaks and ensuring the spark arrestor functions at peak efficiency without rattling.

Tip 3: Periodic Heat Cycling Checks. After your first long run or off-road excursion, allow the exhaust to cool and check the tension on these bolts. The vibration of an aircooled engine combined with the expansion and contraction of metal under heat can sometimes cause hardware to settle. A quick check ensures you don't lose your discs on the trail.
