IAG Performance Subaru EJ20 Cylinder Head Combustion Chamber Modification Service (1 Pair)
The IAG Combustion Chamber Modification machines the original 2.0L EJ20 cylinder heads to lower effective compression and optimize the shape of the combustion chamber to improve burn path. Utilizing our in-house Haas CNC mill and programming, each EJ20 cylinder head’s combustion chamber is reshaped and finished to exacting standards. The modification lowers compression and removes areas of the EJ20 combustion chamber that would cause detonation at higher horsepower and boost levels when mated to the EJ25 short block (commonly known as a “hybrid build”).
