About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and this piston ring set is a good example of that. This set is specifically made for the 2002-2005 Subaru Impreza with the EJ205 engine, featuring a 93.0mm bore and a +1.0mm oversize. If you're rebuilding the top end of your EJ205, these rings are designed to seal properly against the cylinder wall.

This ring set includes rings with dimensions of 1.2mm for the top and second rings, and 2.8mm for the oil ring. These specific sizes are important for ensuring a good seal between the piston and the cylinder wall, which is critical for compression and oil control. Using the correct size and type of rings is essential for the longevity and performance of your engine rebuild.
