If you're looking to really get into the nitty-gritty of your Subaru’s performance, check out these Inconel Exhaust Valves from Supertech. I’ve spent a good amount of time tinkering with my own ride, and let me tell you, these valves are a game changer. They’re crafted with precision and designed to handle the heat and pressure that comes with pushing your engine to its limits. Made from Inconel, they’re tough enough to withstand the rigors of high-performance driving without breaking a sweat.

What’s in the box?

  • A set of 8 valves—enough to replace the entire exhaust setup in your engine.
  • They’re designed to help you squeeze out every bit of horsepower your engine can deliver.
  • Expect a fit that’s spot on. These valves are made with serious attention to detail.
  • Once installed, you can count on them to serve you well for years to come.

Here’s the technical scoop:

  • Head Diameter: 32.50mm (+0.5mm oversize for those looking to push the envelope).
  • Stem Diameter: 5.96mm—just the right size for a snug fit.
  • Length: 104.70mm, tailored to fit various Subaru models perfectly.
  • Material: Inconel, which means they’ll resist wear and tear like a champ.
  • Type: Exhaust valves—because that’s where the magic happens in your engine.

Fitment is key:

  • Subaru Baja (2004-2006)
  • Subaru Forester (2004-2013)
  • Subaru Impreza (2002-2022)
  • Subaru Legacy (2005-2012)
  • Subaru Outback (2005-2009)
  • Subaru WRX (2015)

These valves are especially great for anyone running an EJ20 or EJ25 engine, and they’re designed to fit like a glove. If you’re looking to enhance your ride’s performance without cutting corners, these Inconel valves are definitely worth considering. They’ll help you make the most out of your engine, whether you’re hitting the track or just cruising around town.
