This Perrin turbo inlet hose is a perfect fit for your 2002 - 2007 Subaru WRX, 2004 - 2021 Subaru STI, and 2004 - 2008 Subaru Forester XT. It's made of 5 - ply silicone wire mesh, which is not only durable but also resistant to heat soak. With an inner diameter of 3 inches, it allows more air to flow freely into the system, increasing horsepower, reducing turbo spool time, and improving acceleration. It comes with a 5 - year manufacturer warranty and estimated installation time is about 3 hours. No tuning is required, and installation instructions are provided. Please note that you may need to remove the intake manifold for installation, and it works with the factory turbo, though the 3 - inch turbo inlet won't fit the factory turbo.
Using this turbo inlet hose is straightforward. First, gather all the necessary tools and make sure you have about 3 hours of free time for installation. You may need to remove the intake manifold during the process, so be careful with that. Just follow the included installation instructions step by step, and you won't need to do any tuning. As for maintenance, since it's made of silicone and has stainless - steel wire support, it's quite durable. But still, check it regularly for any signs of wear or damage, especially after long - term use. If you notice any issues, contact the manufacturer as it comes with a 5 - year warranty.
