RK Autowerks Port Injection Kit for BMW Toyota B58 Engines The RK Autowerks Port Injection Kit is designed to meet the demands of high-performance B58 builds. Whether you're chasing big horsepower or seeking to maximize fueling efficiency, this kit delivers reliable results without compromise. Precision CNC-machined and tested in RK’s Texas facility, each component reflects the brand’s commitment to engineering excellence. This kit is fully compatible with both the factory B58 intake manifold and the RK Billet Port Injection Manifold, giving you complete flexibility in your setup. Fueling Confidence with E85 Support E85-compatible fuel lines are included, allowing you to safely run ethanol blends and take full advantage of the power potential that port injection offers. Why Port Injection? Port injection helps achieve a more complete fuel burn by introducing fuel upstream of the intake valve. This results in better atomization, reduced carbon buildup, improved throttle response, and greater top-end power—especially critical at higher boost levels where direct injection alone can fall short.
