If you’re looking to push your Audi EA839 3.0T to the next level, you might want to check out the Forged Piston Upgrades from 034Motorsport and JE. These aren’t just any pistons; they’re crafted with a serious focus on durability and performance, especially for those of us who like to push the limits on the track or the open road.

What sets these JE Forged Pistons apart? For starters, they’re made right here in the USA and are designed using a proprietary forging technology that gives them some serious tensile strength. That means they can handle the kind of extreme cylinder pressures that come with high-horsepower setups without breaking a sweat.

One of the coolest things about these pistons is the optimized compression ratio. Compared to the factory setup, which sits at 11.2:1, these pistons drop down to a more manageable 10.0:1. This isn’t just a random number; it allows for better efficiency, especially when you’re cruising under lighter loads. Plus, with the strength these pistons offer, you can safely crank up the power on your EA839 3.0T engine without worrying about it going boom.

034Motorsport’s decision to go with a lower compression ratio was no accident. With years of experience tuning Volkswagen and Audi engines for racing, they know that a bit of extra timing advance can go a long way in squeezing out more power. And with the risk of detonation minimized, you can really enjoy the thrill of driving without the constant worry of engine failure.

These pistons are forged from 2618 aluminum, which is known for its high tensile strength. JE’s unique Forged Side Relief (FSR) design reduces friction thanks to a narrower skirt width, which means less contact with the cylinder wall. This translates to less power loss and a smoother ride. And let’s not forget about the included JE Pro Seal Piston Rings that ensure a tight seal on combustion pressure, maximizing your horsepower.

Features:

  • Lower Compression Ratio
    • Stock 3.0T Compression Ratio: 11.2:1
    • 034Motorsport Ratio: 10.0:1
  • Heavy Duty Wrist Pins for Extra Strength

Install Instructions:

So if you’re ready to take your S4, S5, or SQ5 (2017 and up) to new heights, these JE Forged Pistons are a solid upgrade. They’re built for performance, backed by experience, and ready to help you unleash the full potential of your engine.
