Rover V8 3.5/3.9


This fabulous kit features a Weber 4 barrel downdraught carburettor and dual plane induction manifold.

The conversion has been developed for improved engine torque and fuel economy. Although initially calibrated for Range Rover 3.5 and 3.9 models, it is also suitable for many other Rover V8 applications, and for those wishing to carry out engine tuning modifications.

For applications other than 3.5 or 3.9 ltr, calibration changes and/or adjustments may be required.

Please note that this is the only official Webcon 4 barrel kit for the Rover V8. There are a number of "Grey" importers supplying similar looking products, however these have not been tested or verified by Webcon.

To ensure you receive only a genuine Webcon kit, please contact a Webcon dealer or Webcon direct.

This kit was developed by Webcon over 20 years ago and since then, many thousands have been sold Worldwide and continue to provide reliable service no matter what the operating conditions may be.
