DSkoiph Air Cleaner Cover 595660 Air Filter 799579 Primer Bulb 594281 Compatible for Lawn Mower BS 550E-550Ex Series 594281 590581 08P502

What It Is

This is a three-piece service kit for Briggs & Stratton 550E/550Ex Series engines: an air cleaner cover (595660), foam air filter (799579), and primer bulb (594281). It replaces worn, clogged, or cracked parts to restore proper air intake and fuel priming on walk-behind mowers, pressure washers, and generators using that engine family.

Fitment & Compatibility

Check before buying:

• Engine model: Must be B&S 550E, 550Ex, or compatible series (e.g., 08P502).
• OEM part numbers: 595660 (cover), 799579 (filter), 594281 (primer bulb).
• Physical fit: Cover measures ~4.5" x 3.5"; primer bulb stem is ~0.5" diameter.
• Cross-references: Also fits some 590581, 594281, and 08P502 applications.
• Not universal – does not fit 450E, 625E, or other B&S series without same part numbers. Measure your existing cover and bulb to confirm.

Key Things to Know

• Quality: Aftermarket kit; users report good seal and fit, but foam filter may be slightly thinner than OEM.
• Installation: Easy – remove two screws for cover, swap filter, and press primer bulb into housing. No tools needed for bulb.
• Gotcha: Primer bulb must be oriented correctly (stem facing engine); forcing it backwards can tear the rubber.
• Durability: Foam filter is washable but degrades faster than paper if exposed to heavy debris. Bulb may harden over winter storage.

Should You Buy It

If you need a quick, budget-friendly fix for a Briggs 550E/550Ex mower that’s running rough, won’t start, or has a cracked cover, this kit is a solid value. It’s not OEM-grade, but for $7 it reliably restores function. Best for DIYers who want to avoid a dealer trip and can confirm their engine’s part numbers match.
