Every diesel enthusiast knows the formula—more air + more fuel = more power. But when dirt, dust, and debris clog your air filter, performance drops fast. The Sinister Diesel Pre-Filter Sock adds a critical layer of protection for your intake system, keeping your filter cleaner, longer, and your engine breathing freely.
Constructed from a high-flow, 5-micron water-resistant mesh, the pre-filter traps dirt and large particles before they reach your air filter—all without restricting airflow or affecting turbo spool. It’s the simplest and most effective way to protect your intake system from dust, mud, and moisture, whether you’re towing, daily driving, or off-roading.
Protect your engine, maintain peak performance, and extend filter life with the Sinister Diesel Pre-Filter Sock—a small upgrade that makes a big difference.
Features:
- Filters Down to 5 Microns – Blocks fine dust, sand, and debris before they reach your air filter.
- No Airflow Restriction – Tested and proven to maintain full performance without reducing power.
- Extends Filter Life – Keeps your main air filter cleaner for longer intervals between services.
- Easy Slip-On Design – Installs quickly and fits snugly over your existing Sinister Diesel air filter.
- Durable, Water-Resistant Material – Designed to handle harsh conditions on and off the road.
- Backed by a 2-Year Warranty – Guaranteed protection and performance.
