4Pack Senior Air filter replacement 695667 499486S Pre-filter Replacement for Briggs Stratton 18-22 HP Intek V-Twin Engines, for 18-26 HP Intek Engines 5111 B, 5111, 5111B

What It Is

This 4-pack of Senior air filter and pre-filter replacements is designed for Briggs & Stratton Intek V-Twin engines (18-22 HP and 18-26 HP models). It includes both the primary foam filter (695667) and the pre-filter (499486S) for lawn tractors, zero-turn mowers, and garden tractors using these engines.

Fitment & Compatibility

Before buying, confirm your engine model number (e.g., 31C707, 33R877) and that it uses the 695667 primary filter and 499486S pre-filter. These fit Briggs & Stratton Intek V-Twin engines with part numbers 695667, 499486S, 5111B, 5111, and 5111B. Check your air filter housing dimensions – the foam filter is roughly 6.5" x 4.5" x 1.5". Not for single-cylinder or older non-Intek engines. OEM cross-references: Briggs & Stratton 695667, 499486S, 5111B.

Key Things to Know

• Quality: 4.8/5 rating (37 reviews) suggests good build and seal; foam material is washable but not oiled (pre-oiled is better for dust).
• Installation: Very easy – remove old filter, slide new foam filter over the pre-filter, then install into housing. No tools needed.
• Gotchas: Pre-filter must be installed under the primary foam filter, not on top. Check that the pre-filter fits snugly around the intake tube – loose fit can let debris bypass.
• Maintenance: Clean pre-filter every 25 hours; replace both annually or after heavy use. Foam can degrade with heat.

Should You Buy It

Yes, if you own a Briggs & Stratton Intek V-Twin lawn tractor or zero-turn mower and want a budget-friendly 4-pack that matches OEM specs. The high rating and low price make it a solid choice for routine maintenance, but if you operate in extremely dusty conditions, consider an oiled foam alternative for better filtration.
