Sinister Diesel Pre-Filter Sock for Cold Air Intake SDUPFS0120

Extra Protection for Your Cold Air Intake System

The Sinister Diesel Pre-Filter Sock for Cold Air Intake SDUPFS0120 adds an extra layer of protection for your air intake system. Dirt, mud, dust, and debris can quickly clog an air filter and reduce airflow to the engine. When airflow drops, engine performance can suffer. This pre-filter helps keep the primary air filter cleaner for longer service intervals while supporting consistent airflow.

Helps Maintain Airflow and Engine Performance

Diesel engines depend on clean airflow for proper performance and efficiency. Because of this, protecting the air filter from excessive contamination becomes important in both daily driving and off-road conditions. The pre-filter captures debris before it reaches the main filter element. As a result, the intake system can maintain more consistent airflow during operation.

Key Features

• Filters debris down to 5 microns
• Designed for cold air intake systems
• Helps extend air filter service life
• Tested with no significant airflow reduction
• Adds extra intake system protection
