Mercedes AMG M177 biturbo performance air intake kit with filters (2015 +)

C63/C63S/GLC63 4.0L biturbo The UPD Cold Air Induction Kit is a simple and clean bolt on kit to add instant horsepower by increasing air flow into the engine by over 30% . The UPD (CAIK) eliminates the restrictive air box inlet design found with the OEM air box and filters by raising the air filters up out of the inlet , adding a tested ultra high flow air filter, plus all hardware to give seamless oem look and opening up the filter for 100% air flow VS only 55% with oem. The restrictive area directly under the air filters is also improved by up to 50%, so more air can flow under and across the filter. Our kit allows for maintaining a stock engine bay look but with cold air intake power flow gains! The UPD CAIK comes complete high flow, re-usable air filters, high quality aluminum brackets, spacers and special stainless steel German made hardware to bolt all engine covers and air filter box in a seamless kit. Our kit is designed and tested to work with our custom high flow air filter
