Getting colder, denser air into the mid-mounted engine is one of the most effective ways to improve throttle response on the 981. Removing the restrictive stock paper filters in favor of high-flow Panel Filters is an excellent entry-level modification. For maximum airflow, upgrading to complete Induction Kits removes factory bottlenecks. Pair these with smooth silicone Induction Pipes & Hoses to eliminate turbulence and amplify the mechanical intake noise positioned right behind the cabin.
