2.5L 24v - KL 

The KL is the 2.5L 24 valve V6 fitted by MAZDA and also used by Ford. This page carries a single item, but it covers the core of the bottom end: a set of six WISECO forged pistons, offered in three bores, 84.50, 85.00 and 85.50mm, and in two compression ratios. The 8.5:1 suits boosted builds, the 11.5:1 suits naturally aspirated engines chasing efficiency. Choose first on the oversize your block has been machined to, then on the compression ratio you are aiming for. No other part family is in stock for this engine at present.
