Upgraded Air Intake Manifold Kit Assembly Compatible with Mercedes-Benz C300 C350 CLS350 SLK280 ML350 R350 E350 Replaces OE# A2721402401 intake manifold 2721402401 272 140 24 01

Replacing an intake manifold is a sensitive job. There are many connectors, hoses, injector seals, vacuum leak spots, precleaning of the area before removing, etc. So, things can go wrong without knowing the root cause. This product was installed carefully, and the result was very good. C300 was strong and sporty after the job.

I was skeptical about ordering this manifold since there were not many reviews on this product, but it was available on Prime, so I ordered. I am so glad I did. It arrived the next day in a customized safe box, inside, the shinning new product was lovely to look at. Everything fit perfectly for my 2006 Mercedes R350 and the car started on the first try. Drives like the first day I purchased it. New set of Gaskets are included, just lubricate the moving parts on the manifold like runners and move them back and forth making sure they are not resistive and move freely before installation.

I installed the manifold in my 2010 E350 and the engine threw a bunch of codes, P0410 (Secondary Air Injection), and P0171 and P0174 (Bank 1 & 2 too lean). I thought I installed something wrong like the gasket or vacuum lines so brought it to a mechanic to take a look. The mechanic, who i trust, said the flapper valves weren't working correctly so they replaced it with an OEM version and it was fine. Their recommendation was to always buy OEM parts. Unfortunately I wasn't able to get to the repair right away so am not eligible to return it either. Waste of money & time.

I'm 3 months and approximately 3,000 miles on my new intake. This item is cheaper and easier than replacing the diverter valves and solenoids. I would recommend purchasing OEM intake gaskets as the ones I received were paper and leaked after installation. I just replaced them with Mercedes sold gaskets and no issues after the reinstall. It was an easy install and the intake is a fraction the cost of a Mercedes made part.

I was going to just replace the broken linkage on the OEM manifold, but after taking it off I decided that the whole manifold needed to be replaced. I was concerned about quality because it's such a cheap price compared to others, but I decided to chance it since it I wouldn't be out a ton of money if it failed. The fit and finish isn't as nice as OEM, but workable. Had to tap a bunch of holes, but that was easy. All the sensors and actuators were included and correct. No issues with the OEM harness. The flap linkage is metal, unlike the plastic OEM one. It's been on the car for a couple of months, and no problems so far. I'm amazed that it was that cheap and worked perfectly.

I was skeptical of this intake manifold that saved me around five or six hundred dollars. Once I got the old intake manifold out I was super happy that it matched up perfectly with no modifications needed.

Love it...easy install...works perfect

Just installed it, and the car runs great! Let's see, I hope it lasts.

Buen precio por la parte comparada con una original y está en específico si es una versión mejorada en algunos componentes. Funciona perfecto en mi MBc350 w203

Fortunately working good I am satisfy with the product till now driving around 900 km with out any issues, Before I bought, I read the feedback and many customers mentioned that no threaded holes but the item I received had threaded holes and typically matching like original. Thanks to saler

Installed and still working after 5 mts, it did trigger 1 time the check engine for the big flap after 3 mts of use but since then it didn't. I did not used the gaskets that came with, they look cheap, I recommend Hengst also for the injector seals and replace the 2 pcs vacuum hose from car to manifold with Mercedes OEM part. You have to tread the top holes, the throttle were already treated.

The item was exactly as advertised! Very happy! Thank you!
