Go to autozone and ask them to put it in for you..lol or o'reillys. Youd be surprised at how much they will help you if you ask, It would be hard for me to tell you how, but under your hood on each side of your radiator, you can probably see back of headlight. If not it may have to be removed, just look how it is held in place, If I didn't help you I will if you will provide me more info, I do this for free to help people, please give a me a good rating, I don't have anything to gain by trying to help but for a better rating

SOURCE: to replace at plug adapter for mercedes c240 year 2005

Hello, If you are talking about the suppressor that connects to the spark plug try this. Disconnect suppressor from plug, take a small screwdriver etc. and pry the top part of the boot slightly away from wire, spray some silicone lubricant in between the wire and boot, hold the wire in one hand and the suppressor in the other, unscrew the suppressor from wire, remember, lefty loosy righty tighty.
When installing new one, lube the wire and the suppressor and screw back together until snug. Do not over tighten.
If you find this information to be correct would you please enter a "fixya" rating.
Thanks, Gator241

Hi, The air filter is located under the engine cover. Just lift off the cover and access the 20mm torx bolts under the cover.
