BMW M44 ITB install
With the help of Haydn the owner of this car we did a lot more research and development than usual on this kit design, lots of flow simulations and calculations were made on every component from the manifolds to the airbox and once again the results speak for them selves.
By fitting the MAF sensor to the inlet of a sealed air box all the original fuel management system was retained, no tuning or modification was made to the ecu and the engine runs extremely well with impressive power gains good economy and the AFR readings well within the standard specifications.
Further gains were made later with sports exhaust and other small improvements to the airbox intake
Later improvements to the production version of the airbox, slightly less bulky and available in both plain FRP or Carbon Fiber finish. Fitted here to an m42 engine again running the original unmodified ECU with no tuning required.
