The naturally aspirated K4J 1.4 16v fitted to the Renault Clio and Megane is served here by a single reference, and that is a deliberate choice: WÖSSNER forged pistons in 79.5mm bore, cut for a 12.6:1 compression ratio. That figure belongs to a hard-worked naturally aspirated build, aimed at entry-level rally preparation where compression does the work boost would otherwise do. No other component is offered for this engine at present. For a full range, with camshafts, adjustable pulleys, cam followers and valve springs, see the page 1.6L 16v - K4M, the 1.6-litre sibling of the same engine family.
