This Caterham Sigma Jenvey Throttle Body Kit has been specifically put together by Northampton Motorsport and is suitable for both the Ti-VCT and Fixed Cam 1.6L 16v Sigma engines as found in the Caterham Seven. Unlike the regular DTH Sigma kit, this kit been designed to fit under the bonnet without having to cut the bonnet, even with an air filter installed.

What’s in the box?

  • Jenvey Direct to Head 42mm throttle bodies
  • Jenvey 19mm air horns
  • Jenvey #6 fuel rail with mounting brackets (one end comes supplied with a blanking cap and the other with a push fitting compatible with the original fuel line)

Please note: The coolant pipe between the radiator and thermostat will foul the throttle bodies so some modification is required. We can supply an additional piece of hose and bypass pipe (as pictured) for an additional cost. The dipstick will also need securing but this is easily done with a P-Clip. Please Contact Us if you have any questions on the installation of this Caterham Sigma Jenvey Throttle Body Kit.

Please also take a look at the Project Area of the website where we detailed the installation of this kit along with engine management changes and potential gains.

Jenvey throttle bodies and all associated accessories are engineered for Motorsport, offering excellent performance, reliability, lightness and value. This kit is ideal for road, track or Motorsport use.
