Using these Manley connecting rods is simple. First, make sure your Subaru model is either a 2002 - 2005 WRX or a 2004 - 2021 STI. If you have an EJ255 engine, use an aftermarket piston that doesn't need a tapered rod. When installing, handle them carefully as they're precision - made. For maintenance, regularly check the fasteners to ensure they're tight. Keep the rods clean from dirt and debris. If you notice any signs of wear or damage, replace them right away. These rods are designed to handle high - horsepower, but don't push them beyond their 1,000+ flywheel horsepower limit. You can buy Manley Pistons separately to go with these rods for an even better performance.
