EWK 17mm Mercedes Benz Spark Plug Wrench Boot Puller

Works great

Key tool here for doing the spark plugs on our M112 V-6 in my wife's e320 wagon. Will also come in handy when I do the plugs on my 2002 ML 500 with the M113 V-8.....at 16 plugs, I'm not looking forward to doing that job, but at least the right tool is at hand. I wouldn't try doing the job without this tool, there is such tight clearance there, that removal and also install of the new wires is far easier using this to, in effect, 'lever' the boot off the plug end, safely and with no real chance of breaking either plug or wire. One tip: Removing the Coils from the valve cover mount allows for more room to angle the wrench. Even though this might seem a hassle, I suggest it especially of you're doing both a plug & wire replacement - which only makes sense as the plugs should go 100 k miles and assuming that to be 5 years +, the wires may be suspect by that time, and due to the accessibility factor, replacing the wires only makes logical sense. I did both the plugs & wires on my wife's e320 and the resulting smoothness of operation is amazing. The engine now feels turbine like: a smooth & seamless flow of power, significantly improved over the old plugs & wires. For all you fellow MB owner who are serious DIY'ers, this is a practical, super $$$ saving 'routine maintenance' procedure !

It worked

This tool actually does the trick in enabling you to remove the boot without potentially breaking the spark plug. It will also limit but certainly not fully prevent you from tearing the rubber boots. If your Mercedes spark plugs have not been changed for 50-70+ miles, expect to tear at least half of the boots, as the rubber will have become bonded to the plugs. If you have never changed these type of spark plugs, be sure to take your time, as it is quite different. You need to pull straight-back, not side to side. This tool helps to get the leverage you need, using two hands. Again, this tool will not fully prevent you from tearing a boot, unless you have previously changed the plugs and used dielectric grease to prevent the boot from bonding to the neck of the spark plugs, unlike what the factory uses, which appears to create the problem in the first place. If this is your first time, buy extra boots from somewhere where they can be returned if not needed.

Not as easy to use.

Great tool! It reaches 11 of the 12 plug wires and pulls them out easy. The rear driver side plug isn’t reachable with this tool so you’re on your own with that one.

Made to last tool. Well designed and a good value for the money.

Changing the spark plugs on my S500 would have been miserable without it. Worked as advertise. Simple design that works really well and saves a bunch of time removing the spark plug wires from the plugs.

As described and works well making sparkplug cable removal easier.

great tool for pulling the plugs on my E430! job went smooth even with the rear plugs! great product

Did the job. Quick delivery from the supplier. Mandatory if one needs to change the spark plugs

Pulled spark plug wires on a 2006 CLS500 with ease. Worth the investment.

All OK, works well.
