Using this intake hose kit is straightforward. First, make sure your car's engine is cool. Then, remove the old factory corrugated inlet hose. Next, install the new 4-ply silicone intake hose using the provided 304 stainless steel worm clamps. Attach the evap purge assembly and the intake scoop standoff assembly as per the instructions. No need to mess with ECU calibration. As for maintenance, check the clamps regularly to ensure they are tight. If you notice any signs of wear on the silicone hose, replace it right away. Keep the hose clean from dirt and debris to maintain optimal performance.
