What is the purpose of the -7cc dish volume?

The -7cc dish volume is a specific design feature that helps to lower the compression ratio. This is particularly useful in turbocharged or supercharged engines, like the 1.8T, where you need to manage cylinder pressure and prevent detonation, especially when increasing boost levels.

What does the ArmorGlide skirt coating do?

The ArmorGlide coating on the piston skirts serves multiple purposes. It helps to reduce friction between the piston and cylinder wall, leading to improved efficiency and potentially lower operating temperatures. It also contributes to quieter operation and provides resistance against seizure, which is crucial in high-performance applications.

Are these pistons compatible with all 1.8T engines?

This specific piston set is designed for the 1.8T 5-valve engine configurations found in various Audi and Volkswagen models. It's important to verify your engine's specific cylinder head and displacement to ensure compatibility, as there can be variations within the 1.8T family.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance. The -7cc dish volume is a key design choice for managing compression ratios in boosted 1.8T 5-valve engines, especially when aiming for significant power gains. This set is designed for builders who need components that can handle the stress of heavy to severe duty race applications, offering improved tensile strength and durability over stock components.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. This attention to detail helps ensure consistent performance and longevity under extreme conditions. The crown is fully machined for a clean, accurate combustion chamber surface, and the pistons include forced pin oiling to keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating reduces friction and noise, while also resisting seizure, making them a well-built choice for demanding builds.

This piston set fits a range of European vehicles, including models like the Audi A4, Audi TT, and Volkswagen Golf. If you're rebuilding the top end of your 1.8T engine for racing or high-performance street use, these pistons are a solid option. Remember that these are not CARB approved and cannot be shipped to California.
