  • Seal your coolant system up JDM tight with a Mishimoto Radiator Cap
  • Custom made to mount in place of your factory radiator cap
  • Rated to withstand up to 1.3 bar (19 lbs) of pressure—far more than any factory radiator cap (depending on model)
  • By keeping a lid on your system, a Mishimoto Radiator Cap helps prevent your coolant from boiling over into the overflow reservoir
  • Finished with the iconic Mishimoto logo to dress up your engine bay
  • Limited Lifetime Warranty included

Harsh driving conditions put a lot of stress on your cooling system. Whether you're drifting around a hairpin turn or stuck in stop-and-go traffic, the pressure levels inside your radiator skyrocket. If anything gives way and vents pressure, your coolant will blow like a geyser. Stay off the sidelines by keeping your coolant in control with a Mishimoto Radiator Cap.

Ready for the track and safe for traffic, Mishimoto Performance Radiator Caps are built to hold a lock-tight seal even when the pressure's on. You see, when your coolant is heated up well beyond the normal boiling point, the last line of defense stopping it from going thermo nuclear is the cap. The glorified cork they install at the factory doesn't have much backbone, but a Mishimoto Cap does. They're rated for up to a full 1.3 bar (19 lbs) of pressure—more than enough strength to keep your coolant coursing through your motor instead of gushing out onto the asphalt.

You never have to fear fitment with a Mishimoto Custom Radiator Cap. Each one is expertly crafted to mount right in place of your stock cap. What's more, they come branded with the legendary Mishimoto logo and are backed by a Lifetime Warranty.
