Using your K-Tuned K-Series Knock Sensor is straightforward. First, check the color of your broken sensor and make sure you've ordered the correct replacement, either green or black. When installing, gently plug it into the appropriate slot in your engine. Be careful not to apply too much force to avoid any damage. As for maintenance, keep an eye on it during routine engine checks. If you notice any signs of wear or damage, replace it promptly. Remember, this sensor does not fit newer model 2012+ K24Z series engines, so always double - check your engine model before use.
