Yes ewalk, I was referring to the products with outlandish claims to get people to buy it. Products that swear to rebuild your entire engine with just one 12 ounce bottle added to your crankcase, or say you will get substantially better gas mileage instantly. Sorry to offend you Sax. I didn't know that you had Dura Lube, Sham Wow and Leak Ender stock. As for E3 spark plugs, I have tried them and have not seen any great improvement. If you have a starting problem and an E3 made it better, well good. Most likely a hotter plug of the same brand as the OEM supplied would have done the same thing for half the price. But if it was quick and easy and worked, great. Most of us won't miss a house payment over a $6 spark plug. I have a set of Split Fire plugs in my wife's car right now. Why? Not because they work better or make a super fancy "flame front" across the combustion chamber. It was because they are platinum tipped and were on sale for $1 less per plug. Do they work better than the Bosch platinums they replaced, no, but they worked just as well. I try to stick with the stuff that works for me. Marvel Mystery Oil, Seafoam, Kano Aero Kroil, Sta-Bil, etc. Sax, I do try new things on a regular basis but not because of outrageous advertisements or some Joe Blow on an internet forum swears he got a 35% horsepower boost by pouring it in. I'm still wanting to try Star Tron fuel treatment but can't find it locally. I agree with rdaystrom. Most of these gimmick products just mask or temporarily hide other problems. Just like running a thicker oil can most times hold down oil consumption in a worn engine just as well as well as some high dollar oil additive that basically just thickens the oil anyway.

Hey Jerk you have a few more threads to respond back to from Sept and October. Try showing some respect to the Senior Forum Members when they ask you for additional information to enable them to better assist you and future members reading this Site. If not quit posting trival questions about push mowers , leaf blowers , engine oils and spark plugs and then not even have the courtesy to respond back in a timely fashion with the requested feedback or at the very least a Thank You for their assistance . How about them Red Sox !

You can also clean the threads with a proper chaser and not remove the head. Some grease will help catch the filings .There are a lot of threads in that head and it likely won't need an insert.

Use an extension on the socket.
