MOTUL AUTO COOL OPTIMAL -37°C is a ready to use long life cooling liquid, based on monoethyleneglycol, using an Organic Acid Technology (OAT) additivation named Organic Tech. Strongly recommended for all cooling systems: passenger cars, heavy duty, construction and agriculture vehicles, gardening, ships, stationary engines

PERFORMANCES
Contains a bitterness agent to prevent from drinking: coolants and antifreezes have a sweet taste but are harmful. Optimal protection of cooling systems against freezing and metallic parts against corrosion. OAT coolant technology provides an excellent thermal exchange and therefore improves engine cooling efficiency and prevents from boiling. This organic technology provides anti-corrosion properties that remain at high temperature and aging. Low corrosion inhibitors consumption allows extended drain intervals. Water pump protection, avoids cavitation. Seals, hoses, pipes and plastic parts friendly.

RECOMMENDATIONS
Ready to use, do not add any water.
Drain intervals: Refer to the manufacturers' recommendation.
Do not mix with non-organic products.
This product should not be used to protect drinking water systems against freezing.
Attention, control or drain the coolant only when the engine is cold. Dangerous. Respect the use and handling recommendations.

Fit perfectly, but questionably thin.
Style: CA11053A
This was an exact fit for my 2017 Kia Forte S. My only convern is that it is half the width of the stock filters. Hopefully the different material will make the difference over time. Didn't notice a loss or gain of torque or acceleration after swapping for my old dirty filter.

Increased MPG!
Style: 33-3131
I don't know if it increases power, but it for sure has an increase of 1-2 MPG. About the same MPG increase as a K&N, but half the price.

Time will tell
Style: CA11053A
As another reviewer pointed out, the OEM paper filter is almost 3 times thicker than this one. All things equal, thicker would mean for filtering surface area. So with less filter media surface area, the filter would clog up quicker. However, since this is washable, maybe that's a moot point. I also noticed on my Hyundai Tucson, the rim of this filter must be slighter thicker because I had a tougher time clipping the filter box closed with this one installed. I am keeping my OEM for now, just in case.
