A high-flow replacement air-filter is the logical first step for those looking for an easy, early and affordable upgrade for their two-wheeler centred around performance. For starters, it is not very expensive. It also requires no modification. Plus, the benefits are tangible. Moreover, unlike older times wherein one would have to jet and re-jet carbs to match the increased airflow to extract the best from this upgrade, today, with FI, it is as simple as plug-and-play.
We took this first step recently for the Hero Xpulse 200 4V with the Ngage Hyper Flow performance air filter. We have used air filters from Ngage before - erstwhile marketed under Moto Wings - and the performance improvement offered by them has been telling.
