Dinan's four-filter kit delivers 18.6% greater airflow than stock (stock: 862 CFM per bank; Dinan: 1,022 CFM @ 28\" H2O per bank), translating to measured peak gains of 7 WHP and 8 lb-ft of torque at 4,750 RPM in a completely bolt-on installation. Deep-pleated multi-layered cotton media and a steel wire mesh core provide the structural integrity and filtration efficiency to make those numbers durable, not just dyno-day results. Fits the factory airbox directly or Dinan's high-flow carbon fiber intake system (D760-0054) without modification.
