The S&B Filters Pre-Filter, part number 20-2942-01, is specifically designed to fit the Round 4 x 12 Inch and Round 4.5 x 12 Inch air filters. Available in a sleek black color, this pre-filter not only enhances the look of your air intake system but also provides essential protection.
Using the S&B Filters Pre-Filter can significantly extend the life of your air filter by preventing harmful debris from clogging it. This leads to improved airflow and horsepower, reducing the frequency of maintenance and saving you money in the long run. Many customers have noted that after installing this pre-filter, they noticed a marked improvement in their vehicle's performance and a longer interval between filter cleanings.
One satisfied customer shared, "I installed the S&B Pre-Filter on my air intake system, and I've been really impressed. It fits perfectly and has kept my filter cleaner for longer. Plus, I love that it looks great!"
This pre-filter is designed to repel water, making it a great choice for those who drive in heavy rain or through puddles. However, it's important to note that while it is effective, it is not waterproof. If submerged, water may still enter the intake system.
The water repellency feature lasts approximately 6-12 months, depending on your driving conditions and how often the filter is cleaned. To check if your pre-filter still has its water-repellent properties, simply spray it with water. If the water beads off, it's still effective; if not, it may be time for a replacement.
Attempting to retreat the pre-filter with additional water-repellent sprays is not recommended, as this could compromise airflow and engine performance. The factory process used to create the water repellency is specifically designed to maintain maximum airflow while preventing water ingress.
