If you fancy skinning your own knuckles and swearing indeterminately at the sky, a DIY option is readily available for just ₤ 3,495.
In the age of downsized, turbocharged engines with little appeal, tuner BBR has instead turned to the tried and tested (and extremely excellent) approach of installing specific throttle bodies to each of the Mk3 MX-5’s 4 cylinders. As any E46 BMW M3 owner knows, ITBs are ace.
