    Dreams do come true

    Great product, design, functionality and customer service. Running ITbs alongside a GT35r making all the noises and power, loving it.

    Very good customer service.

    Andreas helped me with working out what I needed for my bmw to install the ITBs

    BMW M30 swapped E30

    Got my intake a long time ago when I did the swap originally.

    I've been driving it for about 4 years now and havent had an issue with the ITB kit at all.

    My car wouldnt be complete without it. It goes very well for its age, not quite modern quick, but for a 36 year old car its more than enough.


    Got an intake for my E36. Got a lot more power but the sound is what its about.

    BMW M42 ITB Kit
    perfected for performance

    Thousands of hours of research, hundreds of designs and dozens of tested vehicles, we make sure all and every kit performs to a world class standard.

    smoother idle

    By eliminating cylinder cross-talk, very aggressive cams can be run without low RPM stalling and with reduced lumpiness.

    Instant throttle response

    By giving the intake air a short and direct path into the chamber, the throttle response becomes lightning quick.

    increased power

    By allowing each cylinder to consume the same and maximum amount of air, your engine can be run at its optimum performance.

    Engineered with precision.

    Each model kit has undergone serious testing with proven results
