Supertech Black Nitrided Intake Valve Set of 8 for Subaru EJ25 1999-2012 - SIVN-1025-8

If you're looking to give your Subaru a little extra love under the hood, check out these Black Nitrided Intake Valves from Supertech. I’ve had the chance to run these in my own ride, and I can honestly say they make a noticeable difference. They’re not just shiny pieces of metal; they’re crafted with some serious attention to detail. You can feel the quality when you hold them in your hand.

What really stands out is the precision engineering that goes into each valve. With a head diameter of 37.00mm and a stem diameter of 5.96mm, they’re designed to fit snugly and perform like a champ. The length is 120.60mm, which is spot on for what you need in a Subaru. They’re made from black nitrided material, which not only looks good but also adds durability. These valves are built to handle the heat and pressure of your engine, so you can expect them to last for years without any worries.

This set comes with 8 valves, so you’re all set for a complete replacement. Whether you're driving a Baja from '03 to '06, a Forester from '99 to '10, or even an Impreza or Legacy from the early 2000s, these valves are a perfect match. They’re designed to help you get the most out of your engine, enhancing performance in a way that you can actually feel. I’ve noticed improved throttle response and a bit more pep in my step since I installed them.

So, if you’re serious about getting the best performance out of your Subaru, these Supertech intake valves are a solid choice. They meet or exceed industry standards, and trust me, you’ll appreciate the difference they make on the road or off it.
