Supertech Inconel Exhaust Valve Set of 12 for Toyota Supra 1JZGTE 1989-1995 - TEVI-1008-12

If you're looking to really unlock the potential of your Toyota Supra, you need to check out these Inconel Exhaust Valves from Supertech. I've had my hands on these bad boys, and let me tell you, they’re a game changer. Crafted with precision, these valves are designed to take your engine performance to the next level—no fluff, just solid engineering.

First off, you get a full set of 12, which is perfect if you're looking to do a complete overhaul or just upgrade your existing setup. The Inconel material is not just a marketing gimmick; it’s tough and heat-resistant, which means you can push your engine harder without worrying about wear and tear. I’ve seen these valves hold up under extreme conditions, and they really do deliver on that promise of longevity.

When it comes to specs, these valves have a head diameter of 30.00 mm and a stem diameter of 5.97 mm, with a length of 98.10 mm. The fitment is spot-on for the 1989-1995 Toyota Supra, especially if you’re running the 1JZGTE engine. They fit like a glove, and installation is straightforward—no surprises there.

What I love most is how these valves help get the most out of your engine’s performance. You can feel the difference in responsiveness and power delivery. Plus, with Supertech’s reputation for quality, you can count on these valves to provide worry-free service for years to come. If you’re serious about your ride and want to squeeze every bit of performance out of it, these Inconel Exhaust Valves are definitely worth considering.
