Air filter replacement

Post by 702scottc »



What is the average mileage the air filters typically last? I replaced mine 2 years ago and it has right at 15 thousand miles now.

I have the only GL1800 specialty repair shop in the world. Although many will brag about pushing their air filters to above Honda's 12,000 mile recommendation, I get to see the results. To keep the insides of your engine from looking this, follow Honda's maintenance guidelines. Keep in mind Honda says the longest one should push their air filter is 12,000 miles. Doing it earlier is by far better than doing it later.

Below are the insides of various engine areas where dirty air enters the combustion area, and as with all engines, as the explosion occurs, some blow by gets passed the rings which will carry dirty air particles too. This dirty blow-by begins to settle in various places. While it is making it's way past the rings it begins to "sand" away at the rings and cylinder walls. And the results are somewhat predictable ... the engine will be an early oil burner. One can absolute count on that. However, there is no way to predict exactly when that day will come.

That's what I figured. I'm headed out on a long trip this week so I'll change it. I used an OEM filter last time, a little pricey but worth it .

manufacturers recommendations are usually for worst case situations. If you ride in dusty areas you will need to do it more often. Once you change this time you cab judge how dirty it is and if you can go more than the 12,000 miles intervals.

I have been running mine 50,000 miles and they are still not terribly dirty. Honda's service intervals are ridiculous. They say 30,000 miles in cars, what's different? Cars with standard spark plugs and electronic ignition, 30,000 miles, what's different? The engine pictured was not from a dirty air filter, it was from not changing the oil. Air filters get restrictive when dirty they don't allow more dirt through.

In EU they recommend Air filter exchange on 30000 km / approx 19000 miles

Nice ... Europe must have cleaner air than here in the US. If Honda built Wings for China, I'd bet Wings there would need air filters much more frequently.

There are 2 people who benefit from owners not follow Honda's maintenance guidelines ... the owner by putting off the cost, and the repair shop who deals with an owner doing so.
