Jenvey Throttle Bodies

throttle body kits

Why do I want it?

Remember when sports cars had twin Weber carbs? Remember when you could look down the long bonnet, mash the accelerator to the carpet and feel the car squat in instant response, hear the roar of those intakes converting petrol into power in an intoxicating bark as you were pitched down the road, rear wheels scrabbling for grip on the razor edge of acceleration?

Remember the delicious feeling of having your right foot connected directly to your rate of acceleration? Unfortunately you probably remember the poor fuel economy and the constant need to adjust the mixture and tune the carbs...

Well put away those rose tinted specs because instant response is back!

5 Speed and Jenvey Dynamics are proud to bring the responsiveness back in the form of a pair of twin throttle bodies designed exclusively for the Mazda MX-5.

Jenvey throttle bodies combine the instant response and power of a big carburettor with the reliability, accuracy and maintenance free nature of the very latest in vehicle electonics.

The Jenvey Dynamics throttle Body kits include:

  • A pair of throttle bodies (ITB's) 45mm diameter for the 1800, 42mm diameter for the 1600
  • A Jenvey Dynamics EFI inlet manifold
  • A fuel rail
  • Four 40mm long airhorns

Jenvey throttle bodies and all Jenvey throttle body accessories are engineered for Motorsport, offering excellent performance, reliability, lightness and value and are ideal for road, track or rally use.

What does it do?

Put simply, getting 5 SPEED to fit a throttle body kit will give you a significant increase in throttle response, induction sound ambience and of course, power!*
