My 01 E430 car just hit the 90k mark and it is time to change the spark plugs. My question is if it is also recommended to swap the 'Spark Plug Wire Set; Spark Plug Connectors' while changing the spark plugs.

I plan on buying everything from www.autohausaz.com and wanted to find out if the wire set needs to be changed as well prior to placing the order.

Cheers

 

Huh? I don't think you'll need to buy plugs since I think you have direct ignition (coil-on-plug) system. I could be wrong, though.

 

Since you are going to replace the spark plugs..I Would do the wires at the same time as Im Sure they are worn @90K

 

are fine,if not abused in the change process of the plugs by using the proper 17mm offset boot removal tool they will last for another 100k miles.You only remove them from the spark plug end not the coil end.You need the 17mm tool,a set of torx bits from the local auto store,a socket wrench 3/8 in drive a few short extensions like an 1" long,a 5/8 thin walled socket with the rubber plug holder on the inside,and a blanket to cover the fender.16 NGK 7090 plugs at $2.79 each from the auto store and a few hours of your time.
You can follow the diy on benzworld.org or in a few days our spark plug diy will be posted from the get together we did a few weeks ago with Raymond,John,and Jon A C320(tight)and a E320.
