If you’re looking to really dial in your Mazda Miata's performance, you’ve got to check out these Inconel Exhaust Valves from Supertech. Seriously, they’re a game changer. Made for the 1994-2005 Miata, this set of 8 valves is designed to help your engine breathe a little easier, which means more power and efficiency on the road or track.
What’s cool about these valves is that they’re made from Inconel, a super tough material that can handle the high temps and pressures that come with performance driving. Plus, they’re precision-engineered, so you know you’re getting a perfect fit. Here’s the nitty-gritty: the head diameter is 29.00mm (+1mm), the stem diameter is 5.94mm, and they come in at a length of 102.60mm (+0.6mm). That slight oversize helps with flow, giving you that extra edge you want.
And let’s be real—nobody wants to deal with parts that wear out quickly. These valves are built to last, promising reliable performance for years to come. Whether you’re hitting the backroads or just cruising around town, you can trust that these valves will hold up under pressure.
So if you’re ready to get the most out of your Miata’s engine, grab a set of these Supertech Inconel Exhaust Valves. They’re a smart upgrade for anyone looking to enhance their ride without breaking the bank.
