    M20 BMW Complete Bolt on ITB Kit with Carbon Airbox

    This is a complete bolt on kit that will fit ALL m20 bmw engines.

    Angled manifold to clear standard e30 brake booster.

    All our testing has shown this kit to produce peak gains of up to 30rwHp over the standard intake. This is not just gains to the top end but gains made throughout the whole rpm rang

    This kit is available in 2 sizes:

    1. 40mm throttle size with matching 40mm manifold and 42mm trumpets, best suited to standard 2.5L engines
    2. 42mm throttle size with matching 42mm manifold and 45mm trumpets, best suited to larger displacement engines with raised compression, performance headwork and larger duration camshaft.

    This kit comes complete with all the fittings and parts required to install a full idle control circuit. Require the use of e30 m42-318is throttle cable and e36 TPS sensor

    People have managed to use this kit with OEM ECU along with external tuning device but its not recommended. For the best results we strongly recommend using a good quality stand alone ECU

    This listing is for kit sold with gloss finish carbon plenum. We have seen dyno results showing small power gains with the box fitted but most importantly this will allow the option of ducting cold air into the engine which will bring nice power gains on the road or track while also allowing for the fitment of some good quality air filtration without compromising any performance.

    All kits are supplied with polished silver trumpets and polished carbon fiber Plenum/ Air-box. See our other listing if airbox is not required.
