Extract every ounce of cooling efficiency from Koyorad All Aluminum Performance Radiators with a genuine Koyorad Hyper Cap!  This Koyorad Hyper Cap withstands an increased valve pressure rating of 1.3kgf/cm2 (1.3 bar) (18.9 psi) (130 kPa) which increases the boiling point of water and relieves high-performance engines of excessive heat.   A genuine Koyorad Hyper Cap is recommended for use with every Koyorad All Aluminum Performance Radiator (when applicable).  This Koyorad Hyper Cap is manufactured in Japan from high-quality components to ensure longevity and performance from your Koyorad Racing radiator.

Why is increased Pressure Better?

It’s simple.  When water is pressurized, its natural boiling point is increased.  Most modern vehicles are equipped with a 0.9 Bar pressure cap.  Koyorad’s Hyper Cap is rated at 1.3 Bar which increases the boiling temperature of your coolant to 267.80 degrees Fahrenheit.  That is nearly a 56-degree increase over water's normal boiling point.  By increasing the boiling point of water, an engine's cooling system will have the added heat capacity, maximizing performance under ever-changing racing conditions.

The Unsung Heroes of Casual Dining
Style: 100-Pk, Size: 6-Inch
Ah, paper plates, the unsung heroes of casual dining! Whether it's a mountain of greasy burgers or a messy pile of coleslaw, these humble discs of pressed paper pulp stand firm—well, maybe more like a wobbly dance, teetering on the brink of collapse but never quite giving up. They bend, they buckle, but they rarely break. And let's not forget their efficiency: soaking up liquids and grease might seem like a flaw, but who needs napkins when your plate does double duty? Wallet-friendly and hassle-free, paper plates are the champions of cheap dining. For the cost of a latte, you can arm yourself with a stack of plates ready for any impromptu feast. Cleanup is a breeze—just toss the evidence away. In short, paper plates might not be the fanciest dining ware, but they are the unsung champions of convenience. Here's to you, paper plates! May your legacy of casual dining excellence continue for generations to come.

Plates for our anniversary.
Style: 100-Pk, Size: 6-Inch
I needed plates for my anniversary and came across these plates. They were smaller than I expected but they worked out perfectly for us. They are strong and easy to use. They didn't leak or ripped at all. So that's a plus. Great price for the quantity that I received. Definitely recommend them.

Ok but not great
Style: 100-Pk, Size: 6-Inch
Not the thickness I would have expected for the price but do seem to work ok. Very hard to find good quality dessert plates at an affordable price. Probably won’t buy again.

Handy Size, But Flimsy & Not Leak-Proof
Style: 100-Pk, Size: 6-Inch
I actually use these for my cat’s wet food, and while the size is perfect for that, they do have some downsides. What I liked: Great small size for snacks, desserts, or pet food Convenient and disposable Comes in bulk, which is helpful What could be better: Tends to leak through with wet food Plates are somewhat flimsy They stick together, which makes them a little annoying to separate They work fine for lighter or dry items, but with anything moist, you’ll want to be careful or maybe double them up. For my use, they get the job done, just not perfectly. Who this is great for: Light snacks, desserts, or dry foods Quick, disposable use Pet owners for dry food or short-term use Value: Decent for bulk plates, but the quality limits how versatile they are. Final Verdict: Convenient and the right size, but the flimsiness and leaking are something to keep in mind. Best for lighter use.
