Wiseco Audi TT RS 82.50mm Bore 1.165in CH 9.5cc Dish - 5 Cyl

What you get in this box are five forged pistons from Wiseco, specifically made for the Audi TT RS. These aren't your average pistons; they're built for serious racing and high-performance engine builds where durability and strength are absolutely critical. Each piston measures 82.50mm across the bore and has a compression height of 1.165 inches, with a dish volume of 9.5cc. They're designed to handle the kind of stress that comes with heavy to severe duty racing applications.

Wiseco crafts these pistons in the USA using 2618 aluminum, which gives them improved tensile strength over standard aluminum. You'll notice they feature precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is key for keeping combustion pressure where it belongs. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizing, all important factors when you're pushing an engine hard. The fully machined crown ensures accuracy and consistency across all five pistons.

These pistons are also set up for forced pin oiling, which means they get a direct supply of oil to the wrist pin for better lubrication and longevity under extreme conditions. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 5-cylinder engine for racing, these Wiseco pistons are a solid choice for the core of your build.
