Required Maintenance

PRL Motorsports thoroughly recommends visually inspecting the air filter screen inside the HVI at every oil change. It is required to clean the air filter element whenever the screen is no longer visible or at a 30,000 mile interval. When used in a higher dust/arid climate or varied terrain environments, the air filter will require cleaning more often. To clean and re-oil, our #2801 Filter Cleaning & Recharge kits can be purchased direct on our website, or via an authorized PRL Motorsports dealer.

Filter Recharging Guide

1. Pre-Cleaning : Tap the filter or use canned air/compressor to remove any excess debris from the filter. Be careful to not damage the filter.
2. Apply Cleaner : Spray the filter with the special cleaning solution provided in the kit and allow the solution to soak in for at least 15 minutes.
3. Rinsing : Rinse the filter with warm water, clean side to dirty side to flush the dirt and debris outwards from the filter.
4. Drying : Allow the filter to dry naturally. Try to avoid heat to prohibit any shrinkage that could occur in the cotton present in the filter.
5. Oil Application : Re-oil the filter using the filter oil that is supplied in the kit. It is recommended to use a single spray per 2” of filter media. Do not over oil.
