2004 C320. Having all the parts in one kit makes for a stress free ordering process. All the parts fit perfect and was made of high quality materials. The only reason for the 4 star rating and not 5 is because when doing this job you should also have the Air Distribution Hose Connector - P/N 1120180209 ($4) included to be a "Comprehensive Valve Cover Gasket Kit". At minimum mention in the description it's a good idea to order the connector at the same time you order the kit. The part is made of the same materials as the hoses so it can be pretty brittle with a good chance it will break during the replacement process. One side of the connector broke on me and I was out the rest of the weekend without my car. I had to wait till Monday to go to the Benz dealer (not preferred) to purchase the part to complete the job. I am planning on ordering more parts from FCP soon! EDIT: Thank you Greg! We now include this connector in our M112/113 VC Kits --Kyle B

extensive kit, everything needed to do the job the first time. no guessing, and fits perfect, made for a leak free install

I ordered this kit for my 2003 C240 2.8L V6 (A/T) with 137k miles to replace the original Valve Cover Gaskets which were leaking and letting oil run down the back side of the engine. This kit comes with almost everything needed to do a thorough Valve Cover Gasket and PCV System job with the exception of two parts. Breather Hose - CRP-ABV0108 (MB P/N 1120180482) is the PCV hose between the driver's side valve cover and Mass Air Flow Sensor Boot on MANUAL TRANSMISSIONS ONLY. For Automatic Transmissions - use Mercedes Benz P/N 1120180682. (Google these part numbers and you will see the difference) Lastly, do yourself a favor and also purchase the Air Distribution Hose Connector - MB P/N 1120180209. This part is where two of the PCV hoses connect. Due to age/heat this part is brittle and will tear/break when you try to remove the old PCV hoses. I gave this kit 5-stars because of the great customer service I received from Tiffanie. She helped in tracking down the correct PCV hose for my A/T setup which helped make the job turn out perfectly!

Perfect fit, great quality, good price. Glad I went with the comprehensive valve cover gasket kit, as the old breather hoses were difficult to salvage.
