Review on ⚡️ High-Performance MAS Ignition Coils & Plug Wire Sets - Mercedes-Benz C CL CLK ML Class 1997-2009 - OEM# UF359 5C1226 by Thimothy Purnell

Details are important! The assembly/installation of the cables in the reel ports was a bit tricky. The socket in the cable has no guide, so it is off-centre. So if you try to slide it into the coil connector, there's a pretty good chance you'll slide that socket deep into the coil connector on either side of the pin. This can lead to misfires due to the lack of a solid connection. The wellies are fairly durable and insulated which is great. However, this doesn't really give you a chance to see the mating of the pin and socket when assembling the cable and reel. I had to hold the coil close to my ear to hear a click/click that the cable's female (red) connector is aligned with the male contact in the cable. Some sort of guide in the coil connector makes this setup error free/pain free. In any case, the installation in the car went without incident. As mentioned, the leads are a bit long and the spark plug boots may need some sanding. As long as the car runs well. Only driven 100 km so far, no problems.
