Briggs & Stratton 5062K Spark Plug Platinum

I loved that it works great!. An offer I bought along with a genuine air filter for my mower!

Center platinum electrode has a finer point than the standard Champion J19LM. Should last far longer than the Champion, so the story goes. The gold electroplate is a nice touch, and looks great sticking out the top of my Briggs and Stratton 5.0 hp engine on a MTD Yard Machines tiller. Gold does not corrode, and is a good conductor. Did it start the engine on the first pull? Well the engine was cold and I attempted to start it with choke on. It didn't need to be, because it fired right up on the second pull on half choke. But, the best part is it totally smoothed out the motor on both idle and fast, which had been a problem. I bought this plug hoping that would happen, and I'm very pleased. I only let the engine run for a minute, then shut it off. About 5 minutes later it fired right up on run, with no choke. For a few bucks more than a standard plug, I say go for it. I might not have to change the plug again for the life of the tiller with the platinum.

Used this in a snowblower with OE Champion (Briggs & Stratton rebranded) #RJ19LM. The OE copper plugs aren't bad at all, and due to limited use typically only need to be cleaned. But they do have 2 or maybe 3 flaws that these address.1. OE plugs will begin to misfire at idle as they start to get dirty. These platinum tip are known to fire better and stay cleaner longer.2. Platinum tip service life is much much longer. They just don't wear anywhere nearly as quickly as a conventional plug electrode.3. The outside plating will prevent rusting. Sure it's mainly cosmetic but personally I'd rather not see rust anywhere on my engine.These come pregapped exactly 0.030". Installation is a breeze. I use a dab of silver anti-seize on the threads but not mandatory. I don't use a torque wrench but with a stubby ratchet and relatively low hand torque it is easy to feel the crush washer collapse and seat. Stop there.While the price is about double of a conventional plug, since both maintenance is lower and service life is longer, I'd say it's the better value of the two options.Note that the retail packaging has changed slightly compared to the Amazon photo but the plug itself does not appear to have changed.Edit: as much as I like this plug, I've since discovered the Autolite #XST458 Iridium tip small engine plug, which is the next level of upgrade over platinum but is approximately the same retail price. If you buy one of these, assuming it does not somehow get physically damaged, it should outlast the life of any small engine with routine cleaning.

Works great.
