SPDZ1 RH Race 4-2-1 Ramhorn Header – K-Swap K20 / K24 (EG, EK, DC2, DA)

Built for racers. Engineered for results.

The SPDZ1 RH Race 4-2-1 Ramhorn Header is the ultimate long-tube solution for serious K-Swap builds. Whether you’re pushing a high-revving K20 or a torque-heavy K24, this header is engineered to deliver unmatched throttle response, increased horsepower, and cleaner exhaust flow across the powerband — all while maintaining proper fitment in your EG, EK, or DC2/DA chassis.
