Fitment Information: This drain plug is a perfect fit for 2002 - 2014 Subaru WRX and 2004 - 2021 Subaru STI. Features: The Cusco Neodymium Magnet Drain Bolt is an affordable yet valuable addition to your engine. It offers extra protection by attracting and holding harmful metallic particles floating in your engine oil. These particles would otherwise settle at the bottom of the oil pan when the car is not in use. By using this drain bolt, you can reduce oil contamination and friction during engine operation. Regular oil filters have their limits, and the metallic elements they miss will keep circulating in the engine. With the Cusco Drain Bolt, you can take that extra step for better engine care during your next oil change. This drain bolt is made from A7075 aluminum and has a thread pitch of M20 X P1.50. Please note: This item may not be specific to every application. Check compatibility before buying, and some modifications might be needed for proper installation.

Using the Cusco oil drain plug is easy. When it's time for an oil change, simply remove the old drain plug and replace it with the Cusco one. Make sure to tighten it properly to avoid any oil leaks. Before purchasing, always double - check if it fits your Subaru STI or WRX model. It might need a bit of adjustment during installation, so be patient and take your time. To keep it in good condition, clean it regularly. After each oil change, take a look at the magnet on the drain bolt. If it has a lot of metallic particles stuck to it, gently clean them off. This will ensure that the drain bolt can continue to do its job effectively in protecting your engine from harmful contaminants.
