Protect Your Intake Filter with S&B

If you’re running an S&B KF-1059 intake on your 7.3L Powerstroke, the WF-1040 filter wrap is one of the easiest and smartest upgrades you can make to protect both your filter and your engine. Designed specifically for 1999–2003 Ford F250 and F350 models, this breathable pre-filter acts as the first line of defense against dust, moisture, and debris—especially helpful when driving in wet, muddy, or off-road conditions. Think of it like a rain jacket for your air filter—it won’t stop airflow, but it will keep the mess out.

Simple and Effective Upgrade

Whether you’re using a dry or oiled S&B filter, this wrap slips over the element with ease and adds an extra layer of protection without restricting performance. It’s built from a durable, water-repellent material that still allows your intake to breathe freely, so you won’t lose throttle response or efficiency. This is especially useful if you regularly encounter sudden storms, heavy dust, or deep puddles on job sites or trails. The WF-1040 helps keep your air filter cleaner for longer, which means less maintenance and more consistent airflow.
