Product Details

The Genuine BMW 64-21-1-370-807 is an OEM heater core inlet hose designed to deliver hot coolant from the engine to the heater core. This factory replacement hose maintains the proper flow of coolant through your vehicle's heating system, ensuring reliable cabin heat and proper engine cooling system operation.

Key Features:

  • Genuine BMW OEM quality construction for precise fit and durability
  • Engineered to withstand high coolant temperatures and pressure
  • Direct replacement for worn or deteriorated original hose
  • Maintains proper coolant flow to the heater core
  • Factory-spec rubber compound resists heat, chemicals, and degradation

This heater hose is a critical component of your BMW's cooling and heating system. Over time, rubber hoses can become brittle, cracked, or swollen from exposure to heat and coolant. Replacing this hose before failure prevents coolant leaks and maintains optimal heating performance. When servicing your cooling system, it's recommended to replace heater hoses as preventive maintenance.

This company seemed to have the product in stock and at the best price on the net. By shopping at Autoplicity I saved more than 50 bucks and in this economy thats like a weeks pay check. Im saving this seller and doing all my shopping here from now on!!!!

So Far so good.

So far so good thank you

I was looking for KC lights for my jeep, not only CI they have just the ones I was looking for, they were half the price of any local auto shop! Shipping costs were very low to. Thanks!

Excellent prices and fast shipping. I will order from here again

Very good

Very quick. Liked that it linked to Amazon. I originally ordered from Amazon who shipped me a front bearing assembly instead of the rear so having to re-order from you. Correct item received this time. Thank you!

Hurry

I got a great price on the struts I needed for my car. The price quote I recieved from Goodyear was outrageous in price. Autoplicity made ordering my struts easy and affordable and for a graduate student, I needed to save the money.
