M156-A105-ADFU - RMT New Front and Rear Intake Manifold Center Plate for Mercedes Benz C63 AMG 2008-2015, Mercedes Benz CL63 AMG 2008-2010, Mercedes Benz CLK63 AMG 2007-2009

The casting is a beautiful piece and is 5-star-worthy. Unfortunately, the post-machining leaves much to be desired. Due to the threaded holes being blind, the threading process needs to utilize both a plug tap and a bottom tap to finish the threads to the bottom of each hole. RMT neglected to do that... I had to buy a 6mm x 1.0 bottom tap and finish that myself. This was necessary to enable the throttle body bolts to thread in deep enough to retain the throttle bodies.RMT also neglected to de-burr both the casting flash on the threaded holes nor the sharp edges on the perimeter of the plate where the gasket seals.Also, the description says "Throttle Body Plate & Gasket Set" but did NOT include the rubber seal nor gaskets.And FYI, this plate is both thicker and different material (aluminum vs original magnesium), and therefore weighs 2.8 lbs vs 1.9 lbs of the original.
