It is used to adjust valve clearance for my Honda Civic 2007. It’s worth every penny as It helps to reduce my time on working on my car. The size of the valve nut is 10 mm for Honda. The quality is great. Remember to use a feeler gauge through the process to make sure everything is within manufacturer’s specs.

If you have a Honda, then this is a must. Trying to adjust valves without this tool is a headache on top of a migraine. It's possible, but a lot more frustrating.

Tool appears to be well built, it fits perfectly on the valves and gives plenty of space to loosen and tighten the jam nuts.As a warning, however, the tool will NOT fit the valves on a Honda k series motor. I tried to do the adjustment on my TSX but the tool is too large for the jam nuts. You’ll need the 10mm version for the k series and other Honda motors, so don’t make the mistake I made and double check what size the jam nuts are on your engine.Even so, I am satisfied with the quality and will purchase from this brand again.

I bought this tool because I saw it on videos and I’m so glad I did! I did a valve adjustment on my type R for the first time and this tool made it sooooo easy. If you need to do a valve adjustment on Hondas. Get this tool asap!
