A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 2003+ Toyota 4Runner 4.0L cooling system with a Mishimoto Low-Temperature Racing Thermostat and housing! This thermostat is designed as a direct-fit replacement for your aged stock unit. The Mishimoto thermostat has a lower activation temperature (71?C/160?F) compared to the factory thermostat (82?C/180?F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates, on vehicles making more power than stock, or under extreme towing/driving conditions. The stock-style housing will provide a proper seal and installs easily. Like all our Toyota Performance parts, this thermostat and housing includes the Mishimoto Lifetime Warranty.

Torn About Whether to Keep Using
I bought the Vanilla Cardamon flavor, because I'm allergic to mint, and it makes my mouth swell. It tastes nice. The "flavor" doesn't last a long time, so you don't necessarily get that fresh breath feeling. The toothpaste works fine. There seems to be some controversy over whether Nano Hydroxyapatite Toothpaste really protects teeth as well as fluoride, but I know some people swear by it. Obviously, there is also lot of controversy regarding fluoride and whether it's healthy, so I get why this might be a better option for some. I've been using it for about a year, and I got a fairly bad cavity recently, but of course, this is just anecdotal evidence. I'm not sure whether I'll keep using it or not.

Great for sensitive teeth
Size: Pack of 3, 4 Ounce, Set name: E. Ela Mint, Coco Ginger, Lemon Lavender
If you have sensitive teeth, these are great. I had prescription toothpaste and couldn’t get it anymore and picked this up. It’s helped tremendously. No different than normal toothpaste consistency-wise but the flavors are the best.

Truly works and worth every penny.
Size: Pack of 3, 4 Ounce, Set name: E. Ela Mint, Coco Ginger, Lemon Lavender
This is a game changer. All other toothpastes should pack up and close shop. I don’t know what I Was using before, but it was not toothpaste. This is the only toothpaste you should be using.

Great tasting and our son's favorite treat!
Flavor Name: Natural Fruit, Size: 8 Ounce (1 Pack)
Our son loves these! He asks for them every day! For being no sugar they taste great! My kid is obsessed! We have bought these several times at this point and while I can not say whether or not they work in terms of vitamin c, I simply wouldnt know for sure, they do work in keeping him calm in public places. Its great that there is no food dyes in the ingredients too so that I can feel good giving them to him. In terms of quality, we have yet to recieve any broken lollipops or loose, candy or open wrappers so that is great! The paper sticks to start to peel apart, but usually that's by the time the lollipop is finished. I think the amount we paid for what we got was well worth it.
