    They look and perform better than anything else on the market! Hands down the best.

    We got it dialed in and it fires right up and doesn’t miss a beat. Love the looks and the style. I get more looks with this setup that any other I have had. Thank you for a nice piece of equipment.

    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.

    I'm very happy with the results. I love driving this car and giving it a boot just to hear the noise.
    The car made an additional 30+whp, was already tuned previously.

    I bought the LS3 ITB Kit with the Drive-By-Wire Module. The inlet filters do take some of the power so I like to take them out for shows and events.

    Really impressive 40hp power gains and good service.

    I bought an ITB Kit for my E21 with a stroked M20 2.8L motor fitted. My car had a 40bhp incease with the ITBs fitted now producing 268bhp. The kit is great and fitted perfectly. The only criticism is the little dimple in the top of the carbon airbox didn't fit my strut brace so I found a different one that worked.

    The E21 Started live as a 323i 143bhp then we added hotter cam better breathing to get up to 170bhp.

    A few years later fitted a m20 b2.5 from an e30 in there that we tuned to 200bhp but wanted more so that motor then got stroked out to a 2.8 using the crank from a e36 328i with a schrick 286 cam and stand alone ecu it was producing 230bhp.

    It was great running hard on track but a bit lumpy on the road as we had binned the airflow meter when we went standalone. It wasn't great on a light throttle so the ITB'S were what it needed all along to get the fueling dialed in. Its so sharp, the throttle response is something else and now its fast as hell!

    Great ITB System

    When I received my system, I was very surprised how nice it was. The best thing about this system is that it works with my factory ECM and sensors which required very little wiring change. I received very good support when it came to installing and tuning the system the guys constantly kept in touch with me until I was up and running. For a show car this system looks and runs great. It will be hard to find a better ITB system for that price and support.

    WAKE UP YOUR M30!

    Recently installed these throttle bodies on my M30b35 E28( which the whole assembly is featured on my youtube, @m3nameisjosh) and they have transformed my engine. The sound is intoxicating, it is a riot to drive, and install was fairly straight forward. Very high quality kit.

    First off, I just want to say customer service is phenomenal! I had a few questions about the full itb kit for my E34 m20 and Andreas help me out so much. Ended up getting the partial kit which suited my build perfect. Everything came packaged very well! I couldn't be happier with the ibt kit and the help I received from Andreas.

    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.
