Maintaining the air filter on your 2013 GAS GAS EC300E is one of the most essential steps for keeping your two-stroke enduro machine performing at its best. This guide from MotoSport covers all the proprietary cleaning and replacement procedures specific to your bike–an essential maintenance practice for every serious rider.
Why Proper Air Filter Maintenance Matters
The EC300E uses a dual-layer open-cell foam air filter, designed for rugged off-road use. Cleaning and replacing this filter at recommended intervals prevents dust, sand, and debris from entering the engine, protecting your cylinder, piston, and crank bearings. Fuel efficiency, power output, and throttle response all rely on a well-sealed, clean filter.
Cleaning Instructions: 2013 GAS GAS EC300E
- Remove the seat using the quick-release latch and unclip the airbox cover.
- Unhook the holding pin that secures the foam filter in the airbox.
- Carefully extract the filter, taking note not to drop dirt into the air boot or intake tract.
- Gently tap the filter to remove loose debris. Do not use compressed air, as this can damage the foam.
- Wash the filter in a dedicated foam filter cleaner or mild biodegradable detergent. Submerge and squeeze repeatedly until dirt and old oil are removed.
- Rinse with clean water and gently squeeze out excess – never wring or twist.
- Allow the filter to air dry completely away from direct sunlight or high heat.
- Once dry, apply a uniform coating of foam air filter oil, working it thoroughly into all foam layers. A fully-oiled filter is crucial for dust capture.
- Squeeze out any excess oil, ensuring no pool forms at the bottom.
- Carefully inspect the filter for tears or separation at seams. Always replace if damaged.
- Wipe the inside of your airbox with a clean, damp rag to remove any residual dust or dirt.
- Place the filter back onto the holder, making sure it seats flush against the airbox for a tight seal.
- Reinstall the retaining pin, airbox cover, and seat.
When to Replace the Air Filter
- If the foam shows persistent staining after cleaning or physical breakdown such as rips or collapsed sections, replace it with a new dual-layer foam filter designed for the EC300E.
- Routinely check for seal integrity at the rim and seams for the best protection. Even minor leaks can allow damaging debris straight into your engine.
2013 GAS GAS EC300E–Model-Specific Notes
- The EC300E uses a quick-access airbox with a foam filter specific to the 2011–2015 model years. Both ProX and Athena supply high-quality, direct-fit replacement filters, with flame-retardant properties for additional safety.
- Be sure the filter's sealing ring is seated fully around the intake surface for a dust-tight fit–the GAS GAS design relies on a compression fit for its filter retention.
- If your ride style includes frequent deep-water crossings or extremely dusty conditions, inspect and service the filter after every ride.
Expert Tips for MotoSport Riders
- Keep 2-3 filters on hand to rotate between rides for ultimate protection and zero downtime.
- Only use foam air filter oils and solvents for your EC300E–other products can cause filter breakdown and poor sealing.
- Never over-oil, as this can restrict air flow, but always ensure full coverage for maximum engine longevity.
Regular filter service and replacement is crucial for extending engine life and upholding throttle response on your 2013 GAS GAS EC300E. MotoSport stocks genuine and performance replacement filters, OEM parts, and cleaning supplies to keep your bike running strong all season long.
