Jenvey for Porsche

Jenvey Dynamics was founded in 1987 by Richard Jenvey with a view to supplying the motorsport industry with those items he had needed whilst constructing his own racing cars but found difficult to obtain, if he couldn’t find it he designed and manufactured it, hence the design consultancy Jenvey Dynamics was created.One customer design project was for fuel injection throttle bodies and this fitted perfectly with Richard’s own preferences; interesting, challenging, ready for the future and fun to manufacture. All operations were carried out in house and the first unit of our current Bridgnorth factory was acquired in 1993.With the consent of our client we started to manufacture a range of throttle bodies in 1994 and since 2006 Mike Jenvey has continued with the company’s success.The fuel injection range has extended to cover the entire Porsche induction system: manifolds, fuel rails and fittings, air horns, linkages and other associated parts.

Choosing the Right Fit for Your Porsche

Where Jenvey is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

• Typical reasons people choose Jenvey on Porsche builds include sharper throttle response, support for standalone ECUs, and higher airflow capacity on tuned or bespoke engines.
• For Jenvey throttle and induction parts, many owners plan the upgrade as part of a wider engine programme (cams, exhaust, mapping) rather than waiting for outright failure.
• Common symptoms that may point to induction issues include poor idle stability, flat spots, cylinder-to-cylinder airflow imbalance, and drivability problems that persist after basic checks.
• Some “hardware” complaints are actually due to tuning, vacuum leaks, or throttle synchronisation; ruling these out can prevent unnecessary parts replacement.
• Allow for ECU mapping and professional setup when fitting Jenvey systems to a Porsche, as synchronisation, leak testing, and idle control are critical to drivability.
• Jenvey systems can be road friendly on Porsche models when tuned correctly, but expect to spend time on calibration to get the best results.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Rebuild Parts — Engine rebuild parts for Porsche are usually replaced during a planned overhaul or when tests and inspection show internal wear, such as loss of compression, heavy oil consumption, persistent leaks, or abnormal noises; because labour is the major cost, owners often renew chains, bearings, gaskets, seals and fasteners together while the engine is apart to improve reliability.

• Before committing to a Porsche engine rebuild, it is sensible to carry out compression and leak-down tests, borescope inspection, and checks of oil/filter debris and ancillary systems.
• When the engine is out, many specialists replace chains, guides, tensioners, main seals, gaskets and hard-to-access wear items at the same time to avoid future strip-downs.

Jenvey Throttle Bodies — Jenvey throttle bodies for Porsche are typically chosen for performance and tuning flexibility rather than as routine service items, giving precise airflow control for individual cylinders on tuned engines; upgrades are often driven by targets like sharper response, consistent airflow with performance cams, and compatibility with standalone ECUs, though worn shafts, linkages or air leaks can also justify replacement.

• Expect to budget time and resource for mapping, synchronisation and leak checks when installing Jenvey throttle bodies on a Porsche, as they are not supplied pre-mapped and final results depend on the overall engine specification.
• Periodic synchronisation checks and linkage inspection help maintain smooth idle and drivability, especially on engines that see frequent high-RPM or track use.
