The 2017+ Civic Type R may have been designed to attack the track, but it's no secret that it can’t always stand up to the heat. Nothing is quite as frustrating as having to cut your track time short or pull off to the shoulder on a canyon carve due to simmering coolant. Luckily, Mishimoto is here to give the FK8’s cooling system the backup it needs with our 17-21 Honda Civic Type R Secondary Race Radiator Kit.

Employing the use of one of our smaller, yet efficient, radiator designs, we mounted an additional heat exchanger behind the K20C1 with robust steel brackets, tapping in after the Civic’s heater core. Utilizing the airflow generated throughout the engine bay, the Secondary Race Radiator produces additional cooling power for the already overworked stock radiator, keeping you on the track longer. In addition to the supplementary cooling power, the 17-21 Honda Civic Type R Secondary Race Radiator also increases the overall coolant capacity. The Mishimoto Lifetime Warranty is included with the radiator kit to keep your CTR cool and you worry-free.

Features

  • Direct fit for the 17-21 Honda Civic Type R FK8
  • Incorporates additional radiator into factory cooling system for increased engine cooling
  • Utilizes factory aerodynamics for airflow to unique mounting location
  • Full aluminum construction with durable, TIG-welded end tanks
  • Robust mounting bracket design for worry-free installation
  • Increases coolant capacity
  • Mishimoto Lifetime Warranty

Nice tire sealant.
Size: 32 oz
This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire
