Enginetech S84004-STD Premium Standard Piston Ring Set for 2013-2015 Subaru 2.0L 4cyl – Complete Engine Ring Set – Sized by Bore

Description

Enginetech S84004-STD is a premium standard bore piston ring set for 2013-2015 Subaru 2.0L 4cyl engines, sold as a complete set covering all cylinders.

Important Notes:

• Sized for standard (unmachined) cylinder bores. Verify your finished bore diameter with a precision gauge before ordering.
• File-fit and gap each ring to the manufacturer’s end-gap specification for your application before installation. Improper end gap causes blow-by or ring-end butting under heat.
• Replace piston rings as a complete set during any rebuild. One set covers all cylinders for the engine.
• Premium. Steel top. 1.0 / 1.0 / 2.0mm.

Sold as a complete piston ring set – one set covers all cylinders and is required per engine.

Fitment:

2013-2015 Subaru XV Crosstrek 2.0L 4-cyl

Enginetech piston ring sets are manufactured to OEM specifications and offered in both premium and cast grades to match the demands of stock rebuilds and moderate-performance builds. Each set is application-specific, with ring widths and end-gap characteristics matched to the bore and groove geometry of the engine family it serves. Ring sets are sold by bore size – standard for unmachined bores, with oversizes for blocks that have been bored and honed – so verify your finished bore diameter with a precision gauge before ordering, since rings sized for the wrong bore will not seal correctly. Always file-fit and gap each ring to the manufacturer’s specification for your application, and replace rings as a complete set during any rebuild. Enginetech documents every set with the ring stack dimensions, bore size, and cross-references so the correct set reaches the bench the first time.
