Our newly released K-Swap V3 header, designed for both K24 and K20 engines, features a cutting-edge megaphone design with a reverse cone leading to a 3-inch v-band collector outlet. It boasts multi-stepped tubing, smooth porting on the primaries, mandrel bends, a true 4-1 merge collector, and includes 3-inch v-band flanges and clamp. With two O2 sensor bungs—one for wideband—and a secure U bracket tab for the slip-fit connection, this design eliminates the tension loss common with spring connections. Since 2005, PLM has been crafting Honda headers, and this V3 model delivers the best performance, design, and value to date.
