S&B Precision II Air Filter Cleaning & Blue Oil Kit — Larger Cleaner, Measured Applicator

S&B Filters Precision II Cleaning & Blue Oil Kit (88-0009) is a complete cleaner-and-oil system designed to deep-clean reusable air filters and provide a precise, measured oil application for consistent filter performance.

This kit combines a concentrated cleaning spray with a reengineered blue oil applicator and a measuring bottle so you can remove trapped dirt, then apply exactly the right amount of oil without guesswork. Compared with the original offering, Precision II delivers twice the oil volume and about 63% more cleaning solution, plus improvements to the applicator to make oiling easier and more accurate.

How does this kit make filter cleaning easier?

The cleaning spray features a trigger design that lets you soak contaminated filter media quickly and evenly, helping dislodge embedded dust and debris before rinsing. The larger cleaner volume means fewer refills for multiple cleanings or larger filters.

• Trigger-spray bottle for broad, even coverage
• Higher cleaner quantity—about 63% more than prior versions
• Formulation suited to washable filter media (follow filter manufacturer guidance)
• Rinses off clean to prepare the filter for oiling

What makes the oil applicator more precise than standard bottles?

Precision II includes a redesigned blue oil bottle and a separate applicator that lets you meter the oil amount so you won’t over-oil or under-oil the filter. That control helps maintain airflow and capture efficiency without wasting product.

• Applicator bottle included for measured drops or sweeps
• Blue oil color for easy visibility during application
• Improved tip design for targeted, repeatable coverage
• Helps prevent excess oil that can impede airflow

Are there any important precautions or usage notes?

Do not apply oil to brand-new filters—only oil reusable filters after they have been cleaned and fully dried. Follow the filter maker's instructions and allow the cleaner to rinse and dry completely before applying oil.

• Do not oil fresh, out-of-the-box filters
• Ensure filter is clean and fully dry before oiling
• If cleaning multiple filters, the larger volumes reduce the need to repurchase soon
• Consider the Precision II 6-pack for frequent maintenance or fleets

How much product is included and when should I buy a refill?

The Precision II kit provides significantly more oil and cleaner than earlier kits, making it suitable for several cleanings and oilings depending on filter size and contamination level. If you service multiple filters or perform regular maintenance, the optional multi-pack helps avoid running out mid-project.

• Twice the oil volume compared to the original kit
• About 63% more cleaner for repeat use
• Single kit covers multiple cleanings for most passenger-vehicle and light truck filters
• Multi-pack available for heavy usage or professional shops

Who this kit is for: S&B Filters Precision II is intended for owners of reusable air filters, performance enthusiasts, and service professionals who want a reliable cleaning solution plus a controlled oiling system. If you value measured application, fewer refills, and clearer application mechanics, this kit reduces waste and helps maintain consistent filter results. Always match kit use to your filter manufacturer's care guidelines and avoid oiling new filters straight from the box.
