BMW 4 G22 Turbo Heat Shields & Blankets

When it comes to turbo upgrades on the BMW G22 4 Series, the B58 engine platform gives you an exceptional foundation to work with. The stock turbo handles modest power increases well, but enthusiasts looking for serious gains typically turn to proven solutions like the Pure Turbos PURE800 or PURE900 stage upgrades, which are purpose-built for the B58 and offer excellent reliability alongside significant power improvements. Vargas Turbo Technologies also produces strong bolt-on hybrid options that retain the stock turbo housing for a cleaner installation. On the supporting modifications side, you'll want to pair any turbo upgrade with a proper tune from Bootmod3 or MHD, an upgraded intercooler such as the Wagner Motorsport unit, and a high-flow intake like the Eventuri carbon system to ensure the engine breathes efficiently under increased boost. Upgraded fuel injectors and an upgraded charge pipe kit from Burger Motorsports are also strongly recommended to prevent boost leaks. Always address your fueling system before pushing past the stock turbo's limits, and never skip a quality ethanol flex fuel kit if you're chasing numbers above 500 wheel horsepower on the B58.
