Fitment Notes

• Designed specifically for engines equipped with the Honda D15B6 1.5L SOHC engine (1493cc); confirm engine code before ordering
• Standard bore (STD) - for use with a standard, unmodified 2.953" cylinder bore only; not for use on overbored engines
• This ring set is specific to the D15B6 engine code and is not a direct cross-fit for D15B2, D15B7, or other D-series variants without confirming bore and ring groove dimensions

Features

• OE-quality chrome-faced carbon steel top compression ring engineered to meet or exceed original Honda factory specifications for compression sealing and wear resistance
• Cast iron second compression ring designed for effective oil control and blow-by reduction on both the upstroke and downstroke
• Stainless steel three-piece oil control ring assembly with shallow groove design for reliable oil scraping and cylinder wall conformability
• Pre-lapped ring faces seat quickly, virtually eliminating extended break-in time compared to non-OE alternatives
• Ring tension, materials, and coatings optimized for reduced friction and extended service life in OE replacement applications
• CNC-controlled gap chamfer on compression rings optimizes compression retention and minimizes blow-by during normal operation

Product Description

The MAHLE 41618 is an OE-replacement piston ring set designed specifically for the Honda 1.5L D15B6 SOHC engine found in 1988-1991 Civic and CRX models. Built to factory specifications, this ring set restores combustion sealing, reduces blow-by, and brings oil consumption back to normal levels - making it the right choice for engine rebuilds or re-rings on vehicles with this engine code. The chrome-faced carbon steel top ring delivers reliable wear resistance, while the cast iron second ring and stainless steel oil control assembly work together to manage oil migration and maintain cylinder pressure.

As a MAHLE Original product, the 41618 reflects the same engineering standards MAHLE supplies to OE manufacturers worldwide. Pre-lapped ring faces reduce break-in time, and optimized ring tension minimizes friction for better fuel economy and long-term durability. This set is sold at standard bore sizing and is intended for use with a stock, unmodified 2.953" cylinder bore only.
