Great spark plugs, the exact type my motorcycle required. Very good quality plugs, gap already set appropriately. They all come cylindrical cardboard tube over electrode to protect plugs while in the box. So you have no worries of your box being dropped and cracking your porcelain around the electrode.Very clean, crisp threads and installed in motorcycle heads with ease.INSERT tip: using a 3/8" rubber hose approximately 6-8" long, slide it over the top end of plug and use to insert plug into place. If you begin to cross thread during insertion the rubber hose will slip around plug. Whereas, with a ratchet one might be apt to keep tightening at this point, thus ruining the female threads in your cylinder head.Update- July 2015, its been a few years since I have replaced these plugs. Motorcycle still running strong. Great plugs. After initial replacement, my motorcycle had a felt increase and sense in horsepower...not dramatically increased of course but I could tell that these plugs were indeed causing my motorcycle to run with a little pep in her step.ChrisEastern NC

At this price point, it's not worth cheaping out on plugs. I've had too many issues with budget plugs in the past. They aren't worth the headache.NGKs just work and continue to work for a long time.

It’s a Spark Plug, seriously what more can you say. Well to be honest getting hold of these at the moment hasn’t been easy for some reason so thank you Amazon. I needed 4 as it’s good practice to replace the set, one of mine just gave up after 17 years believe that. Great price to.
