It replaces the factory airbox with a high-flow filter sealed inside an insulated heat shield, so the filter draws cooler air instead of engine-bay heat. Bracketry holds everything still under load, so nothing rattles when the engine torques over. Expect more intake and turbo sound than stock.\u003c\/p\u003e\n\u003ch3\u003eHow it sounds and feels\u003c\/h3\u003e\n\u003cp\u003eWith the factory airbox gone, you \u003cstrong\u003ehear the turbo\u003c\/strong\u003e. Roll into the throttle and there's a deep intake whoosh as the B58 breathes in, then the turbo spooling up as boost builds — sound that the stock box was built to muffle.\u003c\/p\u003e\n\u003cp\u003eAt a steady cruise it stays quiet, so it isn't tiring on long drives.

Where it pays off is cooler air feeding the turbo on hot days and back-to-back pulls, the sound every time you accelerate, and the headroom it gives you when you add a tune later.\u003c\/p\u003e\n\u003ch3\u003eHow it looks under the hood\u003c\/h3\u003e\n\u003cp\u003eThe black textured heat shield and aluminum pipe replace a plastic box with something that looks like it belongs on a performance car — with the Kings Mods Auto crown on the shield.\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M340i — G20 and G21, 2019+\u003c\/li\u003e\n\u003cli\u003eBMW M440i — G22 and G23, \u003c\/li\u003e\n\u003cli\u003eBMW M240i — G42, 2022+\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eB58 3.0L six-cylinder only.\u003c\/strong\u003e It does not fit the four-cylinder 330i, 430i or 230i.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSend us your VIN before you order and we'll confirm it fits in writing, free.\u003c\/strong\u003e It takes us a few minutes and it is the single best way to avoid a return.\u003c\/p\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4\" high-flow air filter\u003c\/li\u003e\n\u003cli\u003e4\" aluminum intake pipe\u003c\/li\u003e\n\u003cli\u003eInsulated heat shield with edge trim\u003c\/li\u003e\n\u003cli\u003eSilicone coupler and stainless clamps\u003c\/li\u003e\n\u003cli\u003eBillet SAI breather adapter with bracket and breather filter\u003c\/li\u003e\n\u003cli\u003eBrackets and all mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAluminum intake pipe, 4\" diameter\u003c\/li\u003e\n\u003cli\u003eEnclosed, insulated heat shield in a black textured finish\u003c\/li\u003e\n\u003cli\u003eAnti-rattle bracketry\u003c\/li\u003e\n\u003cli\u003eKings Mods Auto branded\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitting\u003c\/h3\u003e\n\u003cp\u003eIt replaces the factory airbox using the brackets and hardware in the box.
