Volevo aggiungere questo test che secondo me andrebbe messo in evidenza su ogni discussione riguardante il filtro aria per conoscenza di tutti:
https://www.nicoclub.com/archives/kn-vs-oem-filter.htmlRiguarda le auto, ma viene continuamente preso in considerazione su ogni mezzo. Se qualcuno vuole evidenziarlo può essere un bene x tutto il forum...se lo avete già visto meglio.
Le conclusioni sono importanti, a meno di mezzi super-modificati come scritto.
The PROBLEM is you spent a chunk of change on a product that not only DID NOT increase your horsepower, but also let in a lot of dirt while doing it! Now how much is a lot? ANY MORE THAN NECESSARY is TOO MUCH!
If a filter is using “better airflow” as their marketing tool, remember this….Does it flow better? At very high airflow volumes, probably. BUT, our engines CAN’T flow that much air unless super-modified, so what is the point? The stock filter will flow MORE THAN ENOUGH AIR to give you ALL THE HORSEPOWER the engine has to give. And this remains true until the filter is dirty enough to be recognizeable. At that point performance will decline somewhat. Replace the filter and get on with it.
