Subaru OEM Connecting Rod Subaru STI 2004-2007 | 12100AA181

This is the factory - made connecting rod designed for the STI's 2.5 - liter EJ257 engine. It's perfect for those rebuilding a damaged engine or building a new one from the ground up. You can buy these connecting rods individually or as a set of 4. Remember, Subaru of America only warrants parts installed on a car with a matching VIN by a CERTIFIED Subaru Dealership. For example, if you install an STi block in a WRX at a non - certified shop, don't expect a warranty claim if something goes wrong. Use your best judgment.

Using these connecting rods is straightforward. When you're rebuilding or assembling an engine, just replace the old or damaged connecting rods with these new ones. Make sure they fit properly and align correctly with the other engine components. As for the warranty, always have the parts installed by a certified Subaru dealership on a car with a matching VIN. This way, you can avoid any issues if you need to make a warranty claim. For maintenance, keep an eye on the engine's performance. If you notice any strange noises or a drop in power, it might be time to check the connecting rods. Regular engine servicing by a professional will also help keep these parts in good condition.
