Wiseco Volkswagen ABF 2.0L 16V Golf/Ibiza/A4/Octavia 10.5:1 CR 83.5mm Bore +1 Oversize Piston Set

If you're building a serious performance engine for your Volkswagen ABF 2.0L 16V, like those found in Golf, Ibiza, A4, or Octavia models, this set of four forged pistons from Wiseco is a solid choice. These pistons are designed for a 10.5:1 compression ratio and feature an 83.5mm bore, which is a +1 oversize, meaning they're intended for engines that have been bored out to match this size. They are made from 2618 aluminum, a material known for its strength, and are forged and machined right here in the USA.

Wiseco packed these pistons with features for high-performance applications. You'll find precision ring grooves, anti-detonation grooves, and other features to help seal the rings better, which is crucial for maintaining compression and preventing blow-by under heavy loads. The crown of each piston is fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction, make operation quieter, and resist seizing, all important for engines that see a lot of hard use.

These pistons are built to handle severe duty and racing conditions, making them a great option for builders who are pushing their engines to the limit. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's installation instructions for specific details on fitting these to your ABF engine build.
