Tired of playing the guessing game on what components to install in your engine to handle more power? Let us help! Our forged internal kits are a perfect way to stop worrying about what may or may not work! We at AMTuned are proud to be specialized engine and vehicle builders. With building more Audi specific engines than any other shop in the Americas on a monthly basis, we know what works and what does not, we also know what works better! Our seasoned data points of building record breaking engines has brought us here to this design!
As of 12/18/24 we are the first company to incorporate asymmetrical piston skirts into the EA839 aftermarket piston design. We use a larger skirt on the major thrust side and a smaller skirt on the minor thrust side of the piston. The advantages of this design are numerous, including a piston design that is lighter and generates less friction since there is less surface area on the minor thrust side. Thus results in a lighter yet stronger piston design that stays cooler during operation from less heat being generated. We also incorporate a engine bank specific offset to make these pistons run as quiet as possible. All of these benefits attribute to making more power!
We have designed these pistons with the "mild to wild" spectrum of enthusiast in mind. Components and piston design are capable of handling over 250 HP per piston (1500hp per set). Compression ratio is 9.5:1, 93 Series pins to handle whatever you throw at it, Nitride ring package, and JE's 2618 Alloy because it is the best! These pistons can work in a bore range of 3.3267” through 3.3279”. Exceeding this bore range may bring excessive cold start piston slap. Have more questions? Ask us, we build engines with the products we sell!
