Jenvey 45mm throttle bodies for sale

Jenvey 45mm throttle bodies for sale

Product Overview

For sale is a complete Jenvey 45mm individual throttle body (ITB) kit — supplied as a full, ready-to-install package including ECU, wiring loom, 8 green injectors, and a manifold built to fit the MI16 engine. This is a top-quality Jenvey setup, and the inclusion of all ancillary components makes it a genuinely complete induction solution requiring no additional sourcing before installation.

Jenvey throttle bodies are widely regarded as the benchmark individual throttle body product in the UK and European performance and motorsport market, known for their precision manufacture, consistent airflow characteristics, and broad application coverage. This 45mm specification is appropriate for high-revving naturally aspirated four-cylinder applications where maximum airflow and sharp throttle response are the primary requirements.

About Jenvey Throttle Bodies

Jenvey Dynamics is a UK-based manufacturer and the most respected name in individual throttle body systems for performance and motorsport applications in Britain and Europe. Their products are used across club racing, national championship, and international motorsport — as well as in the most demanding road and track day builds — and are specified by engine builders, competition teams, and specialist workshops who require consistent, high-quality throttle bodies that can be relied upon across a full season of use.

The 45mm bore specification of this set is well suited to high-revving, naturally aspirated four-cylinder engines where airflow capacity and throttle response are prioritised. At 45mm, each throttle body provides sufficient bore area to support strong power outputs in the upper rev range without compromising the throttle sensitivity and linearity that make ITBs preferable to a single throttle arrangement for competition and spirited road use.

The use of eight injectors — two per cylinder — is a configuration associated with sequential, high-flow fuelling setups that allow precise fuel delivery across a wide rev range, and is commonly used in both road and competition applications where the ECU’s fuelling resolution and flexibility are important to achieving the desired power curve and fuel economy balance.

MI16 Application

The Peugeot MI16 — used in the 205 GTI 1.9, 309 GTI, 405 Mi16, and related vehicles — is one of the most celebrated four-cylinder naturally aspirated engines in the European hot hatch and motorsport tradition. Its twin-cam, 16-valve architecture and short-stroke character make it highly responsive to induction improvements, and the replacement of the original injection system with a quality individual throttle body setup is one of the most effective performance modifications available for this engine platform.

A Jenvey 45mm ITB setup on a correctly prepared MI16 transforms the induction character of the engine — delivering immediate, linear throttle response, a strong intake note, and a meaningful improvement in high-RPM power delivery compared to the standard injection arrangement. The included manifold ensures a correct, properly engineered fitment without the need for bespoke fabrication.

Ideal For

• Peugeot MI16 engine builds — 205 GTI, 309 GTI, 405 Mi16, and related applications
• Club motorsport, circuit racing, and hillclimb builds using the MI16 platform
• High-performance road and track day cars requiring a complete, top-quality ITB solution
• Engine builders and workshops seeking a matched, ready-to-install Jenvey kit
• Buyers who want a complete package without the cost and time of sourcing ECU, loom, and injectors separately
