Oversized domed High-Flow TriFoamﾙ air filter designed to provide increased surface area and dust capacity. This extra surface area provides even more airflow with lower restriction, to ensure that the largest volumes of the coolest possible air is available to the engine at all times. With the filter rated to 600bhp, this gives great ﾑheadroom' for any future upgrades you may have planned, and ensures that the intake system is operating comfortably within its capacity at all times. This maximises efficiency and improves drivability and torque throughout the rev range - turbocharger spool dropped nearly 500 RPMs, reducing turbo lag and creating faster turbo response.
