Mishimoto 15-19 BMW M3/M4 Racing Thermostat - 100CThe Mishimoto racing thermostat for the BMW M3 M4 2015+ F8X and G8X is designed to help your cooling system operate at peak efficiency, whether you're cruising to your local car meet or tearing up the track. Our thermostat begins to open 9F (5C) earlier than the stock thermostat at 212F (100C). That allows precious coolant to flow into the radiator and start shedding heat sooner. Couple this thermostat with a Mishimoto performance aluminum radiator

Got this to replace cabin air filter on 2020 Honda Civic Sport, as it said it was a direct fit… It does fit but not perfectly! Holding it next to the filter you can see the size difference, with the original being slightly longer. I noticed a whistling sound from the AC at full blast right after install. I believe this noise is caused by the small gap left in the retainer box with the slightly smaller filter. Luckily it is not incredibly loud, but it’s still there. The quality of filtration seems to be much better than stock filter, but the fitment not exact for vehicles mentioned above.

Will continue to repurchase

I have purchased this product multiple times for my Honda CRV. Works great and is actually pretty easy to install. I will definitely repurchase once the time comes to replace again. Great value for the price compared to at the dealership

Good engine filter at a fair price

Worked for my 2018 Honda CR-V. Arrived quickly. Make sure you check the shape of your filter before ordering. I originally ordered a rectangular filter that Amazon said would work for my car. I was able to return it and order the correct one.
