  • I purchased this socket to get the bottom bank of spark plugs in my dodge 4.7L engine. I had the remaining 6 out in no time. I highly recommend this socket if you have the 4.7L engine with 16 plugs in it. With a couple of different extension lengths attached to it, a user will be able to do a full spark plug service without needing another tool. Great addition to my toolbox.
  • OMFG YES! THIS one is for the 2010 – 2016 4.7 RAM. I searched everywhere locally for this and never found one that even came close. I made my own for the top 8 but even it was too big for the lowers. This one fits all 16 with room to spare and can handle the torque needed to replace spark plugs. You will need extensions but if this was 10 inches long it wouldn’t fit the bottom row. Buy this one instead
  • PROS: o very affordable compared to other thin wall 5/8 sockets o seems of good qualityCONS: o NoneNeeded a thin wall socket to change the spark plugs in my Dodge Dakota 4.7L, and the three standard 5/8 spark plug sockets that I have would NOT fit into the holes where the spark plugs are recessed. After much searching, I decided to try this 16 mm socket, as it is only .004 over. It worked just fine and doing the job myself saved me a chunk of money.
  • This socket fits a 2002 BMW R1150RT. It’s thin enough where it doesn’t hit the walls of the valve covers. It seems to be well-machined; there isn’t any slop/play when using it.
  • Worked well for me to change spark plugs on a 2004 BMW R1150 GSA. Thanks to other reviewers for confirming fitment on similar bikes.
  • Bought this to change the plugs in my 2008 Dodge Ram 1500 with 4.7L V8 with 16 spark plugs. It is not the hemi engine. The top row of spark plugs on each side of the engine are recessed down in the heads under the individual coil packs. You need a thin wall spark plug socket to get them out. Some people just grind down a standard socket to get it to fit but why take the chance. The price on this socket was well worth it and made the job easy.
  • Used to change plugs on sv650 to NGK (1275) CR8E. The fit wasn’t tight enough to hold the plug and not let it fall so I just used some masking tape which worked great. You’ll need an extension to get the plugs out. The front one you’ll want a shorter extension so you don’t have to take the radiator off to get it out. Since I didn’t have a short extension when I did mine I just drained and removed the radiator and horn.
  • Worked great on my Mercruiser 350 MAG MPI, it sure is tough crawling into cavity to change spark plugs, but the socket fit and worked!
