Has anyone used or head of YCK Sportscars modified plenum system for the zetec engine?

any good ?

I saw it at Stoneleigh maybe two years ago. It looked very good and a friend who has a Zetec engined Westfield was thinking of using it on his car.

Its fabricated from steel so maybe a little heavy?

The friend never got round to swapping his carbs for injection though so NO EXPERIENCE.
