Description
Product Overview
The iFJF 697014 Air Filter is a premium direct replacement for Briggs & Stratton and John Deere lawn and garden equipment. A clean air filter is the single most important maintenance item for small engines — a clogged filter starves the engine of air, causing rich running conditions, poor fuel economy, hard starting, and accelerated cylinder wear. This filter is manufactured to meet or exceed OEM filtration specifications at a fraction of dealer pricing.

Symptoms of a Dirty Air Filter
- Engine hard to start or requires choke when warm
- Black smoke from exhaust (rich fuel mixture)
- Reduced power under load — mower bogs down in tall grass
- Increased fuel consumption
- Backfiring through the carburetor
- Oil contamination from fuel wash-down past piston rings
Installation Guide
- Park the mower on a level surface, engage parking brake, and remove the ignition key
- Locate the air filter housing — typically on the side or top of the engine
- Release the two clips or loosen the wing nut securing the cover
- Remove the old filter and wipe out any debris inside the housing with a clean rag
- If equipped, transfer or replace the foam pre-filter
- Insert the new filter, ensuring the rubber seal seats evenly against the housing
- Reinstall the cover and secure the clips or wing nut — do not overtighten
Frequently Asked Questions
Q: How often should I replace this air filter?
A: Briggs & Stratton recommends replacement every 25 operating hours or once per season. In dusty conditions, check the filter every 8–10 hours and replace as needed.
Q: Will this fit my John Deere LA series tractor?
A: This filter fits John Deere models with Briggs & Stratton 31-series engines. Most LA series tractors use Briggs engines, but please verify your engine model number (stamped on the valve cover) before ordering.
Q: Can I clean and reuse this filter?
A: No. This is a paper-element filter designed for single use. Attempting to wash it will damage the cellulose media and compromise filtration. Always replace with a fresh filter.
Q: What's the difference between 697014 and 697153?
A: Both are the same filter form factor. Different part numbers reflect different packaging or supplier codes used by Briggs & Stratton over the years. This replacement fits all of them.
Q: Does this include the foam pre-filter?
A: The primary paper filter is included. The foam pre-filter sleeve (if originally equipped on your engine) should be inspected and can be washed with soapy water, dried, and lightly oiled for reuse.
