BBTV 4216 Engine Piston Ring

Engine piston ring set for 92.00 mm bores

Part number 4216 is an engine piston ring set built for 4-cylinder applications with a standard oversize and a 92.00 mm bore. It is specified for Toyota and Mazda fitments, including Toyota 4Runner, Toyota Pickup, Mazda MPV, Mazda B2600, and Toyota Celica applications.

Key features

• Standard oversize configuration for 92.00 mm engine bores.
• Grey iron top ring and second ring construction for consistent sealing performance.
• Phosphate surface treatment on the top and second rings for added surface protection.
• Steel rail and stainless expander oil ring design for oil control.
• Fits 4-cylinder engines with groove dimensions listed at 1.5 mm for the top and second ring grooves.

Detailed description

Part number 4216 is an engine piston ring set intended for 4-cylinder cylinder block applications that use a 92.00 mm bore and standard oversize dimensions. The ring package uses a grey iron top ring and grey iron second ring, with phosphate surface treatment on both compression rings and a chrome-treated oil ring assembly. These material and finish choices support ring sealing, oil control, and wear resistance in the cylinder bore. This part cross-references Monroe Shocks & Struts (e.g., 12886P, 12887P) for the same application.

Compatible vehicle coverage includes Toyota 4Runner, Toyota Pickup, Mazda MPV, Mazda B2600, and Toyota Celica. Use part number 4216 when matching bore size, groove dimensions, and engine configuration for the correct application.

What this part is used for

• Restoring compression sealing in worn or rebuilt engines.
• Controlling oil consumption caused by worn ring packs.
• Addressing blow-by from reduced cylinder sealing.
• Replacing rings during engine overhaul or rebuild work.
• Matching standard bore specifications in 4-cylinder engines.

Installation notes and tips

Verify bore diameter, ring groove dimensions, and engine configuration before installation. Confirm that the cylinder bore measures 92.00 mm and that the application calls for standard oversize rings. Follow the engine builder’s ring gap and break-in procedures during assembly.

Quality assurance

Use part number 4216 as a specification-based replacement for the listed Toyota and Mazda applications. Confirm all measurements against the engine during rebuild work to ensure proper fitment and sealing.
