⚓ Why You Should Regularly Change Your Boat Engine Air Filter – And Use a Quality One
1. Keep Your Engine Running Smoothly
A clean air filter ensures your engine gets the right air-fuel mix. A clogged filter chokes performance, increases fuel use, and can cause rough running.
2. Protect Against Damage
Marine engines operate in harsh, salty environments. A dirty or poor-quality filter lets in dust and salt particles that can seriously damage internal parts - leading to costly repairs.
3. Improve Fuel Efficiency
Restricted airflow causes the engine to burn more fuel. A fresh filter helps maintain better fuel economy and smoother throttle response.
4. Why Go Genuine or Premium Aftermarket?
* Better Fit: Cheap filters often don’t seal properly, letting unfiltered air in.
* Superior Filtration: Quality brands trap finer particles without reducing airflow.
* Built for Marine Use: They’re more resistant to humidity, salt, and vibration.
* Peace of Mind: Using OE-level filters protects your engine - and may help with
warranty compliance.
5. False Economy of Cheap Filters
You might save £10–£20 upfront, but risk hundreds (or thousands) in engine wear or fuel waste. It's not worth the gamble.
In short: change your air filter regularly, and don’t skimp - your engine, fuel bill, and wallet will thank you.
