look under heading (brands) for je pistons then in applications look for ford 2.0L dohc zx3 which is just other name for the focus and part number 185915, just a word of warning these parts are meant for the black top zetec, i have use them in the silver top, but because i've done a zvh the compression ratio worked out @ 8:4:1 so i had to use a de-comp plate to get down to the Desired 7:8:1 so unless you get some custom pistons made from someone like ian howell of area six who will probably have them off the shelf you would have to make do with a de-comp plate.. there just an extension of the block, if you go to www.ferriday.co.uk he can make you an excellent Reliable one
