The BMW 3-Series is a range of well-known German autos that have been prowling American highways and European autobahns for many generations. These cars are designed with a lineup of 4-, 6-, and 8-cylinder gasoline and diesel engines backed by precisely-shifting manual and automatic transmissions. There’s absolutely no doubt of any kind that various mods alike to cat-back exhausts, cold air intakes, and performance chips can add more horsepower, although those will be just incremental improvements. If you need to get substantial power increase for your vehicle, use BMW 3-Series performance engine parts.

The stock engine on your 3-Series is a reasonably well-tuned road engine, designed with certain compromises for fuel economy, emissions, production cost, etc. If you're going to tune it for whatever purpose, we have you covered. Different parts like camshafts with variable lift, ported cylinder heads, superchargers, turbochargers, and more are gathered here, all designed to add significant horsepower increases to your Bimmer. BMW 3-Series engines enjoy quite a considerable reputation for packing excellent, high-revving dynamics, superb quality, and of course undeniable potential for serious modifications. Considering all the mods that you can make, your Bimmer will surely stand up to the “Ultimate Driving Machine” slogan like no other auto on the road!

    Awesome!
    When the product arrived as per usual I inspected it and it looked great! Just so happens I ordered the wrong part because of a miscommunication with my mechanic. So I never installed it hence the three stars because I'm unsure how easy it will actually be but from personal experience it should be cake.
