A thermostat helps getting your transmission up to optimal temp quickly, and keeps it there.

The only thermostat with a patented design that closes 100% when you need it to.

With a correct sized oil cooler kit, you with have full temperature control on your transmission.

The termostat opens up about 10c lower than most OEM thermostats, giving you better control of your transmission temps.

The typical stabilization temp is 74C (165F)

Activation temp is 71C (160F)

Full flow temp is 83C (181F)

 Please add ptfe hose ends for a complete install with our oil cooler kits.

Improved Racing's Flow Series Compact (FSC) oil thermostat is an ultra-compact unit designed for use in cooling systems for transmissions, differentials, transaxles and small engines where flow rates do not exceed 5 GPM. This thermostat is perfect for engine oil cooling in motorcycles, ATVs, go karts, and other small engines.

The device's unique, patented internal design (US patent 9,772,632) ensures a low pressure drop by placing the bypass valve mechanism completely out of the primary oil flow. This arrangement also allows for a compact design.

Without a thermostat, oil and transmission fluid coolers are likely to over-cool the fluid, delaying engine warm-up and resulting in horsepower loss, excessive engine wear and reduced gas mileage. Oil thermostats perform the critical function of bypassing the cooler until the oil has reached its minimum operating temperature.

The thermostat maintains the oil exiting the engine at the rated minimum temperature in most conditions

 

  • Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels
  • Patented, high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
  • Maintains a minimum fluid temperature according to the typical stabilization temp in the table below, +/- 2°F (+/- 1°C)
  • Allows a small percentage (less than 10%) of fluid to continually circulate through the cooler to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
  • Rebuildable
  • 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
  • Lightweight at just 7.5 ounces (212g) without brackets or fittings

So great, that I own 4 pairs of these Sampeel pants!
Color: Pattern Leopard, Size: Large, Color: Pattern Leopard, Size: Large
I own 4 pairs of these pants because I love them so much! I receive many compliments when I wear them. They are stylish, comfortable, and a great thin material that keeps you cool while looking professional. I am 5" tall and can wear them with heels without needing them to be hemmed (which is unusual for me when ordering pants). They have an elastic waist band with drawstrings so I can wear them while losing weight, they don't wrinkle easily, and they have pockets! Great pants for a great price! I will continue to purchase more throughout the summer.

The good with the bad
Color: Pattern Kah, Size: XX-Large
Photos in listing depict a LINEN pant - in the close up's you can clearly see a linen/cotton like material. To my surprise, these pants are a silky, polyester material. There is NO stretch - I am glad I purchased a size larger than what I consider my " roomy " size. These style is also depicted as a beige and black color pattern, they are more of a light mauve color out of the packaging. Took a steamer to them to get the wrinkles out. Suitable for tall girls ( I am 5'9 ) and wearing them with 3 in wedge. They are cute - dressy enough for a business casual office setting or a date night. Probably not the best for hot humid weather as they are not breathable.

Incredibly comfortable and perfect for summer!
Color: Pattern Leopard, Size: X-Large, Color: Pattern Leopard, Size: X-Large
I have to admit, I was a little skeptical about these pants at first. When I initially opened them, they didn’t feel like they had much stretch, and the fabric felt a bit cheap to the touch. However, once I actually put them on, my opinion completely changed! They are so incredibly comfortable and have a great, effortless drape. The material is lightweight and breathable, making them absolutely perfect for warm summer days. They are easy to style (looked great paired with a simple tank and a denim jacket!) and feel wonderful to move around in. I am so glad I gave them a chance—I would definitely purchase these again!

Cute and comfortable
Color: Pattern Leopard, Size: Medium
Comfortable and cute. A little long but still wear them with no issues. The material is light but synthetic so not really breathable. I foresee wearing them often.

Love these shirts
Size: Small, Color: Watermelon, Number of Items: 1
Love the fabric. They feel so much better than some of the other shirts I have. They’re thicker and just feel nicer. Love this color too. Got a small and also have another color in medium. Both fit, just depends on how casual I want to look. I’ll be getting more!
