I would definitely recommend this to any owner of a high mileage 2003 Impreza Wrx who hasn't had their intake manifold replaced. I would recommend having an experienced Subaru mechanic do the installation. It's just not an easy install unless you remove the entire intake plenum. Be prepared to purchase all surrounding hoses and vacuum lines from a dealer. Everything becomes brittle and hard and will break when the old pipe is removed. After the installation is complete, it works beautifully. It is definitely a durable tube made from durable materials. If you try this setup without dismantling the plenum, good luck. Along with this I also bought a Mishimoto intercooler hose kit. Excellent purchase
