The DENSO Iridium Long Life spark plug was specifically designed for long service life and consistent performance in the latest, most advanced production cars

DENSO's patented iridium alloy is more durable than even platinum, allowing the center electrode to be shrunk to only 0.7mm in diameter. This produces a dramatic improvement in ignitability and spark plug life.

Closely related to platinum and exhibiting even tougher qualities, the rare metal iridium is an ideal material for spark plugs. A fine-wire, 0.7mm iridium center electrode is 360-degree laser welded in place using an exclusive DENSO process, and then matched to a platinum ground electrode. This pair of precision-formed, premium-metal electrodes dramatically extends the plug's useful life.

Features and Benefits:

  • Fine-wire iridium center electrode
  • Platinum ground electrode
  • 360 degree laser-welded spark tip
  • Sustained spark performance over 100,000 miles
  • Withstands higher pressures and temperatures
  • Reduced spark plug wear and erosion

The DENSO Iridium Long Life plug has been selected as original equipment on many of the world's top cars, including those from GM, Toyota, Honda, and Mitsubishi. There's a simple reason for that: these manufacturers needed the best.

The sheet is too short for my liking
Color: Heather Grey(flat Sheet Only), Size: King
This king sized top sheet wasn’t quite long enough for a good tuck-in. Can’t comment on wearability because I won’t be using it. Did not return because I had washed it

Warm and Soft
Color: Solid Forest Green(flat Sheet Only), Size: King
I wanted a sheet that felt warm in the cold weather. Upon reviewing several other sheets, I took a chance on this type. I’m happy I did, no more cold feet in bed! It washes and dries (on low temp.) very well too.

So I’ve purchased these twice
I purchased these sheets twice because I like them that much. I’m really particular about the texture and material of the sheets I use. After trying jersey sheets about 5-6 years ago, I refused to go back to microfiber. They have the feel of a t-shirt, but it’s your bedding. I love the feeling for my pillowcases, too. This brand’s sheets fit my mattress perfectly. My mattress is a queen sized Casper mattress and 11 inches thick. I’m also a restless sleeper. If the sheets don’t have deep enough pockets, the corners become loose and the fitted sheet tries to escape the mattress. These stay perfectly in place no matter how much I move. As a general note, though, since I see this a lot—PLEASE check the thickness of your mattress! Not all sheets have the same pocket depth! If your mattress is 8 inches thick and you’re buying sheets that are for 6 inches of thickness, it’s not going to fit right! If your mattress is 8 inches thick and you’re purchasing sheets that are for 11+ inches of thickness, they’re more than likely going to be too big, but more likely to stay in place if you buy too small. Still, loose sheets tend to bunch on the actual sleep surface and create uncomfortable fabric ridges. Don’t do that to yourself. Buy the right sized sheets for your mattress! For me, these are perfect! I love the colors available. I tend to buy lighter grays and teals for my bed. They survive my restless sleeping and yucky, sticky humidity of northeastern coast summers. The color doesn’t bleed out when washed. They’re such a soft, comfy texture. The other thing about jersey knit sheets is that the top sheet drapes over your body with a bit more weight. Microfiber is lighter and doesn’t give you the ‘completely covered’ feeling that I find I love about the jersey knit sheets. The jersey knit sheets, I find, because of the material weight, naturally sit and slightly conform to the form they are draped upon. Once again, being a restless sleeper, I do not have to worry that my tossing and turning will cause the sheet to attempt escape from my bed and body on its own. But they also do not make me feel additional warmth. I do not like being hot when I sleep. They are perfectly cool on their own or with a light knit blanket on top. They won’t trap in heat that you don’t want them to. If you want to trap heat, add a warmer blanket. They do tend to be a little on the expensive side in comparison to other jersey knit sheets, so I tend to wait for the sales to grab them! But I really, really like this brand.
