Anyone tried or any comments to make on these HRC made filters. There isn't any foam or paper inside. Just stainless steel mesh inside and out. Designed primarily for the track, but do they filter enough. i.e dust, for regular use? Fireblade CBR1000RR CBR RR Air Filters Cleaners Filter Genuine HRC Honda Racing | eBay
No cotton, no sponge or paper then with a few 1000 miles no engine.That air filter is race only cos the engines are refreshed frequently .You need dust protection in a filter for prolonged engine life.
