Mishimoto 2016+ Honda Civic 1.5T (Incl. SI) Aluminum Performance Radiator

Keep engine temperatures under control on your 2016-2021 Honda Civic with the Mishimoto Performance Aluminum Radiator. The 2016-2021 Honda Civic is an incredible platform for a daily driver, weekend autocross machine, or full track build. However, pushing the stock cooling system reveals it's one greatest flaw: an underperforming cooling system. To help solve this issue and keep your Civic pushing the limits longer, we've designed an extremely precise all-aluminum radiator that provides both enhanced durability and cooling efficiency.----The foundation of the Mishimoto Performance Aluminum Radiator is the 36mm-thick two-row core. Our engineers performed extensive testing to create a fin composition that would produce maximum heat transfer. This efficient core is fully TIG-welded to precise aluminum end tanks, which mate perfectly with all factory equipment. Our radiator features a massive 43% increase in fluid capacity over stock for increased cooling capacity and endurance on the track or street. In addition, the Mishimoto core design provides a 36% increase in external fin surface area to help transfer the heat out of your coolant and into the air. The results are lower coolant temperatures and quicker coolant temperature recovery, making this the ideal upgrade for your 2016-2021 Honda Civic. This radiator includes a magnetic drain plug to help keep debris from clogging your cooling system, and as with all our products, this radiator includes the signature Mishimoto Lifetime Warranty for a lifetime of performance.

Reference Information

Radiator, 2016+ Honda Civic 1.5T Aluminum Performance Radiator

Mishimoto performance radiators are designed and engineered to maximize cooling efficiency, boost engine functions, and, most of all, protect your engine from overheating. Many stock radiators can't handle the additional heat that comes higher horsepower levels. So, swap out your stock radiator for an all-aluminum Mishimoto.

Key features and benefits of Mishimoto performance radiators include:
• Available for universal and exact fit applications (no cutting or modifications required)
• All-aluminum construction for optimal heat dissipation, improved strength, and reliability
• Increased cooling capacity due to their massive core size
• 100 percent brazed aluminum core for minimal distortion, low stress, and clean joints
• Available in various sizes with 2-row or 3-row cores
• TIG-welded for clean, strong welds and increased durability
• Magnetic drain plugs capture metallic debris or fragments
• Included high-pressure 1.3 bar cap raises the coolant boiling point for greater safety and efficiency
• Automatic transmission and accessory coolers included where applicable
