FAQ

Q1: How do I confirm this piston ring set is compatible with my specific 6BG1 engine?
A1: Compatibility is determined by the engine model and serial number (ESN). We strongly recommend providing your engine’s full model designation and serial number to our sales team for verification before ordering, as there may be sub-variants with different specifications.

Q2: What is included in a “set,” and is it for one cylinder or the entire engine?
A2: This part number (1-12121115-0) typically refers to a complete set of rings (compression and oil rings) for a single piston/cylinder. To overhaul an entire engine, you will need one set per cylinder. Please confirm the quantity required for your engine (4-cylinder for 4BG1, 6-cylinder for 6BG1).

Q3: Are installation instructions or technical specifications provided?
A3> While detailed factory service manuals are not included with the parts, our technical support team can provide essential installation guidelines, such as recommended ring end-gap specifications and proper ring orientation.
