Mishimoto Aluminum Coolant Expansion Tank - 17+ Civic Type-R (FK8/FL5) / 24+ Integra Type-SThere's no question that the 2017+ Honda Civic Type R is built to perform. From gaping grills, towering spoilers, and bright red splattered on every surface, Honda made it clear that the FK8 and subsequent FL5 are designed for speed. Where we have already improved on other components for improving speed, we turned to the longevity of the sporty Civic with our Aluminum Expansion Tank. The Mishimoto 2017+ Honda Civic Type R Aluminum Expansion Tank

There's no question that the 2017+ Honda Civic Type R is built to perform. From gaping grills, towering spoilers, and bright red splattered on every surface, Honda made it clear that the FK8 and subsequent FL5 are designed for speed. Where we have already improved on other components for improving speed, we turned to the longevity of the sporty Civic with our Aluminum Expansion Tank. The Mishimoto 2017+ Honda Civic Type R Aluminum Expansion Tank removes the eyesore that is the conspicuously beige stock tank from the engine bay, replacing it with a sleek all-aluminum design that looks more at home under the hood with the option for a color-matching Rallye Red or stealthy black micro-wrinkle finish. Where the plastic tank is great for mass production, it's destined to fail with repeated heating and cooling cycles. Mishimoto's expansion tank design will take the worry out of containing your coolant and can stand up to the oven that is the Civic Type R's engine bay. Mishioto have incorporated internal baffling within their tank to keep your coolant level during aggressive driving. The Mishimoto Aluminum Expansion Tank also includes a sight glass for quick visibility on fluid levels and is covered under the Mishimoto Lifetime Warranty for a worry-free install.

  • Direct for the 2017+ Civic Type R (FK8/FL5) / 24+ Integra Base / Type-S
  • 100-percent aluminum, fully-welded construction for maximum durability during repeated temperature transitions
  • Internal baffle keeps coolant near overflow port during aggressive driving, preventing air entry into coolant system
  • Sight glass allows for easy visibility to check the coolant fluid level
  • Includes Mishimoto filler cap and retains ability for use of stock cap
  • Available in micro-wrinkle black and Rallye Red

Purchase Includes:

  • (1) Aluminum tank with Sight Glass
  • (1) Mishimoto 19PSI Filler Cap
  • (1) Overflow Hose
  • Mishimoto Lifetime Warranty

Great Air Filter
Size: 9.6" x 11.1" x 2.2"
Some review’s will say “it’s an air filter, blah, blah, blah”. These reviews are written by the same people that think “water is water”. I’m not one of those people. I’ve noticed that the air smells better, cleaner. I’ve also noticed that the air blows a little stronger. It’s very easy to install, fits perfectly and it’s reusable so it saves you money over the long term and it reduces landfill waste.

THE cabin air filter to use!
Size: 9.6" x 11.1" x 2.2"
I replaced the OEM cabin air filter when I bought my truck, like I always do. 2019 & 2020 Ram 1500's suffer from an underperforming AC system in the summer due to a blend door in the dash not closing completely. Having any kind of restrictive cabin air filter only exacerbates the problem. I bought this filter on the recommendation of many owners who had done the same with great results. I was presently surprised at the increase in air flow coming out of the vents. I also like that in K7N fashion, it is washable and reusable, effectively making it a lifetime filter. Don't overthink it. Yes it costs more, but you will save $$ in the long run with this filter. I am sure this filter fits many other makes & models of vehicles and will improve the airflow of any vehicle it is installed in.

Easy to install and fits great
Size: 9.6" x 11.1" x 2.2"
Fits great and seems better quality than any paper filter. Nice rubber edge makes a good seal and the airflow is good. Used in a 2023 Ram 3500. Installation was easy. So far it appears to filter out all the dust and odors.

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!
