This grey powder-coated kit includes a 4\" turbo inlet for increased airflow (with tested gains of up to 25 HP when paired with a Max Effort tune), a high-flow air filter with removable lid and hydrophobic pre-filter cover, plus upgraded 3\" driver-side (hot) and 3.5\" passenger-side (cold) intercooler pipes. The heavy-duty 14-gauge aluminum construction with smooth mandrel bends eliminates the restrictive factory 2.5\" resonator-equipped pipes and leak-prone plastic\/rubber components. The kit comes with all necessary high-quality hardware, silicone boots, seals, and stainless steel T-bolt clamps for a durable, easy installation that optimizes flow while protecting the MAF sensor, turbo, and engine airways.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4\" Turbo Inlet\u003c\/strong\u003e – Increases airflow with up to 25 HP gains when used with a Max Effort tune\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Flow Air Filter\u003c\/strong\u003e – Removable lid for easy inspection and maintenance with included hydrophobic pre-filter cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\" Driver-Side (Hot) \u0026amp;
