If you're looking to squeeze every bit of performance out of your ride, the Black Nitrided Exhaust Valve by Supertech is worth your attention. I’ve had my hands on these valves, and let me tell you, they’ve got some serious quality packed into them. Designed with the latest tech in mind, these valves are not just your average replacement parts—they're engineered to help your engine breathe better and run smoother.
This set comes with eight valves, which is perfect if you're working on a rebuild or just want to refresh your setup. The precision in the design is noticeable; they fit like a glove and have a solid feel to them. You can expect these valves to hold up for years, giving you peace of mind while you push your engine to its limits.
Now, let’s dive into some of the specs that make these valves stand out. The head diameter is 29.50mm, with a slight oversize of +0.5mm, which means they can help optimize your exhaust flow. The stem diameter is 5.97mm, and the length measures in at 99.50mm, making them a solid choice for those specific Toyota models. Plus, they’re made from Black Nitrided EV16 material, which adds durability and resistance against wear and tear.
Speaking of fitment, these valves are perfect for the Toyota Celica from 1988 to 1993 and the Toyota MR2 from 1991 to 1995. If you own one of these classics, upgrading to these valves could really enhance your driving experience.
So, if you’re serious about getting the most out of your engine, consider these Supertech exhaust valves. They’re a solid investment for anyone looking to improve performance without breaking the bank.
