Raceline has worked with Jenvey Dynamics for many years, most recently on the direct-to-head throttle bodies for the Duratec enigne. With the years of very positive experience we have had, we are convinced that the Jenvey throttle design is the lightest, most reliable and cost effective throttle body arrangement on the market. Racline stocks throttle bodies to replace sidedraught carburettors for a wide range of standard manifold applications, but the Zetec is our core interest. Available in either 42mm, 45mm or 48mm sizes, and finished in either red or black crinkle powder coated finish, the throttle sets come machined with o-ring grooves to seal directly to the manifold, and include idle bleed adjustment.
