Great product!
You know NGK means quality and the price for these was just right. It came and was just what I needed. I did gap it to make sure it was right, but after the install, my 4 wheeler cranked right up and ran great. I highly recommend this brand and this product.

Cheap, quick and easy maintenance!
My 2002 Honda 350 Rancher doesn't get a whole lot of use, but when I need it to work I'm usually depending on it to clear snow off approximately 500 yards of driveway in Montana. In other words, it needs to work when I need it work. Changing out spark plugs is a simple thing to do, and it's become part of my annual maintenance to keep everything up and running. NGK makes really good stuff, and this plug has worked perfectly for me.

Stop wasting money on iridium spark plugs
Absolutely a waste of money to buy iridium plugs for your motorcycle. I know this for a fact as when I first purchased my bike, I wanted the best of everything. K&N filters, ethanol free gas, ceramic coating, custom brakes and rotors, on and on and yes of course iridium spark plugs with overpriced aftermarket plug wires for 10 times the cost of these. At some point along the way my bike just didn't have the guts it used to. I even took it to a local mechanic with no help. To make a long story short it ended up being the iridium plugs i installed. I was told to throw my old copper plugs back in and even though they were all but fouled the bike ran perfectly. The old timer was right. Iridium plugs are for cars. I spent a lot of time and money to learn this lesson and wanted to take the time to leave this review in hopes of helping a fellow biker avoid my mistake. Sounds crazy based on science but I say no to iridium plugs and yes to $3 NGK DPR7EA-9 Standard Spark Plug any day of the week. I am so happy to have my Suzuki powerhouse back!
