If you're diving into the world of performance upgrades for your Subaru, let me tell you about the Tomei EJ Racing Valve Set. Tomei has been in the game since 1968, starting out as a race car tuner in Japan. Over the decades, they've really honed their craft, becoming a go-to name in motorsport. Their background in racing means they know exactly what engines go through when pushed to the limit—whether that's on the track or just tearing it up on the streets.

These valves are built to handle the heat and strain that come with high-performance driving. We're talking about serious quality here; Tomei uses top-notch materials that can withstand the intense conditions of a turbocharged engine. They've designed these oversized valves specifically to boost airflow, which translates to more power. The intake valves measure in at 37mm and the exhaust at 33mm, both crafted to optimize flow rates. The thinner stem design reduces airflow resistance, making the whole system more efficient and lighter than the stock components.

What I really appreciate is Tomei's attention to detail. They've engineered these valves to strict tolerances because even the smallest measurement off can lead to engine failure. You want peace of mind when you're pushing your car, and these valves deliver just that. Plus, they've improved heat resistance and corrosion resistance, so you know they'll hold up under pressure.

Here's a quick rundown of what you get:

  • Improved fatigue rate
  • Enhanced heat resistance
  • Better corrosion resistance
  • Increased airflow, leading to more horsepower compared to factory valves
  • Valve Diameter: Intake 37mm, Exhaust 33mm
  • Stem Diameter: 5.96mm
  • Stem Length: Intake 103.85mm, Exhaust 104.2mm

These valves are designed to fit a range of Subaru models, including:

  • Subaru WRX EJ20 Turbo (1994-2021)
  • Subaru WRX STI EJ20 Turbo (1994-2020)
  • Subaru WRX EJ25 Turbo (2010-2022)
  • Subaru WRX STI EJ25 Turbo (2005-2014)

So, if you're looking to upgrade your engine's performance, the Tomei EJ Racing Valve Set is definitely worth considering. They're designed for those who want to push their Subaru to the next level. And if you need installation instructions, you can find them here.
