This geometry introduces extreme boundary-layer turbulence and limits the total surface area exposed to laminar incoming air. At higher boost pressures, the factory inlet tract chokes compressor feed lines, increasing intake air temperatures (IATs) and forcing the ECU to retard ignition timing under sustained wide-open throttle loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis intake spacer kit alters the physical plane of the intake box assembly by elevating the filtration plane above the bottom housing bottleneck. By increasing the plenum volume immediately preceding the turbocharger compressor inlets, this design optimizes cross-sectional flow distribution across the filter face, reduces pre-turbo vacuum loss, and minimizes hot-air stagnation. Fabricated with direct-fit mounting interfaces, the kit allows unchoked induction flow to satisfy peak volumetric efficiency without triggering mass airflow error codes or requiring sensor harness relocation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCold air intake spacer kit (filters not included)\u003c\/li\u003e\n  \u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2011-2020 Mercedes Benz E-Class, CLS-Class, SL-Class, S-Class, GL-Class\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eM278 4.7L BiTurbo V8 \/ W212, C218, R231, W221, W222, X166\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e429 hp \/ 516 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2020 Mercedes Benz E-Class E550 4.7L\u003c\/li\u003e\n  \u003cli\u003e2011-2020 Mercedes Benz CLS-Class CLS550 4.7L\u003c\/li\u003e\n  \u003cli\u003e2011-2020 Mercedes Benz SL-Class SL550 4.7L\u003c\/li\u003e\n  \u003cli\u003e2011-2020 Mercedes Benz S-Class S550 4.7L\u003c\/li\u003e\n  \u003cli\u003e2011-2020 Mercedes Benz GL-Class GL550 4.7L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the W212, C218, R231, W221, W222, and X166 E-Class, CLS-Class, SL-Class, S-Class, GL-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2020 Mercedes Benz E-Class, CLS-Class, SL-Class, S-Class, and GL-Class equipped with the \u003cstrong\u003eM278 4.7L\u003c\/strong\u003e biturbo engine.
