Using the K - Tuned Crash Bar is easy. Simply install it on your 2006 - 2011 Civic Si as per the included instructions. As it's designed to be the first line of defense against road obstacles, it'll protect your oil pan during daily driving. When you're out on the road, don't worry too much about small bumps and obstacles that could potentially damage your oil pan. Just drive as you normally would. For maintenance, regularly check the crash bar for any signs of damage or loose parts. If you notice any significant damage, it's a good idea to replace it. Also, make sure to keep it clean to prevent rust and corrosion, which can weaken the bar over time.
