Ported and Polished Lower Intake Runners

The HalferLand Performance PPR-GEN123 is a set of meticulously ported and polished lower intake runners engineered to enhance the performance of Honda/Acura J-Series engines. These runners feature precisely gasket-matched intake side inlets for optimal flow and have their inner diameter opened to the maximum possible extent while preserving structural integrity. The runners are finished with a smooth, high-shine polish and are initially offered in a bare metal state, with optional ceramic enamel finishes available in Gold Nugget, Gloss Black, or Gloss OEM Silver for added heat reduction. This product is part of HalferLand Performance's core program, offering flexibility for customers. You can choose to send in your existing intake runners for the Port and Polish (PnP) service, or opt for a core replacement where HalferLand provides the modified parts. Specific fitment is crucial, with options available for various J-Series engine generations, including Gen 1 (J30a1, J32a1, J32a2, J35a1-a4), Gen 2 (J30a4-5, J32a3, J35a5-a9, J37a1), Gen 3 (J35Z ALL, J37A2 and UP, J35Y1-Y2), and a specific one-piece runner option for Gen 3 (J35Y4 And UP) engines. Additionally, customers can select core exchange options, including sending cores before shipment, keeping cores with a core charge, or sending cores after installation for a refund. Further customization and performance enhancements are available. Options include adding an HLP High Carbon Thermal Intake Manifold Gasket to reduce heat soak and lower intake temperatures, with specific gasket options tailored to different J-series engine codes. The product listing also details various core exchange options and the availability of optional heat-reducing ceramic enamel finishes to further optimize intake temperatures.
