Fitment Notes

• Fits VW/Audi 2.0T FSI EA113 timing belt-driven engines only (20mm wrist pin). Does not fit EA888 Gen1/2/3 timing chain-driven TSI/TFSI engines.
• This is an oversize (+0.50mm / 83.0mm bore) piston set. Engine block must be bored or verified at 83.0mm before installation.
• Oil squirter clearance should be verified prior to installation on applicable engines.
• Audi A4 B7 BUL (220hp DTM Edition) shares the same block architecture and is supported by this piston set.
• Does not fit the high-output Audi S3 (8P) BHZ engine variant (265hp), which uses a different internal architecture.

Features

• Forged from 2618 T6 high-tensile aluminum alloy - the preferred material for forced induction and nitrous-fed race engines.
• Dish crown design (-11.25cc) with smooth flowing radii for optimized flame travel within the FSI direct injection combustion chamber.
• FSR (Forged Side Relief) construction reduces skirt-to-wall friction and sheds weight through reduced skirt width and shorter pin boss design.
• JE's patented Perfect Skirt coating minimizes cold-start wear, reduces piston slap, and eliminates false knock signals on computer-controlled engines.
• Dome/dish surface ships ready to install - no deburring or surface preparation required.
• Precision CNC-machined ring grooves maintain tight tolerances for consistent ring seal under sustained high-boost operation.
• Compatible with turbocharged and nitrous oxide applications at competition-level power levels.
• Engineered specifically for the EA113 combustion chamber geometry and direct injection system requirements.
• All four pistons balanced within tolerance for smooth, vibration-free engine operation.
• Rings, wrist pins, and wire locks included - no additional hardware required for assembly.

Product Description

The JE Pistons 353834 is a complete forged piston set engineered exclusively for the Volkswagen/Audi 2.0T FSI EA113 timing belt-driven engine. Used across the MK5 Golf GTI, MK5 Jetta GLI, B6 Passat, EOS, Audi A3 8P, A4 B7, TT 8J, and A6 C6, the EA113 is a well-established direct injection platform with a strong performance aftermarket. These pistons are machined from 2618 T6 forged aluminum alloy and feature JE's FSR (Forged Side Relief) architecture, which reduces reciprocating mass and minimizes piston skirt contact area for lower friction and improved ring seal. The deep dish crown (-11.25cc) is precisely profiled for the EA113's direct injection combustion geometry, delivering a 9.25:1 compression ratio at standard deck clearance - a reliable foundation for both street and track-focused turbo builds.

At 83.0mm bore (+0.50mm oversize), this set is intended for blocks that have been professionally bored oversize, whether due to cylinder wear, damage repair, or as part of a performance rebuild. JE's patented Perfect Skirt coating is applied to every piston in this set, reducing cold-start wear, eliminating piston slap, and suppressing false knock detection - all critical considerations when running tighter piston-to-wall clearances in a computer-managed forced induction engine. The precision CNC-machined ring grooves maintain consistent tolerances for long-term ring seal integrity under boost or nitrous use. Every set ships with matching rings, 20mm straight-wall carbon steel wrist pins, and wire locks - everything needed to complete the bottom-end assembly without sourcing additional hardware.

These pistons are the right choice for enthusiasts and engine builders looking to rebuild or upgrade the EA113 FSI bottom end for high-output applications. Whether the build target is a stage 2+ street car, a dedicated time attack platform, or a full competition drag build, the JE 353834 delivers proven race-validated strength in a ready-to-install forged package. Builders should confirm oil squirter clearance prior to installation and verify the engine carries the EA113 timing belt-driven architecture before ordering, as this set is not compatible with the later EA888 TSI chain-driven engines.
