This is SpeedFactory's\n  1.9 Bar cap, and it does something simple but important: it raises the pressure in your cooling system,\n  which pushes your coolant's boiling point up by roughly 35°F. That's 35 degrees of extra margin before\n  things start to boil over, and when you're leaning on the car hard, that margin is exactly what keeps\n  you out of trouble. It fits standard 42mm radiator filler necks and every SpeedFactory Race Cooling\n  System fill pot, and it cleans up the look of your engine bay while it's at it.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhy More Pressure Means A Cooler Head\u003c\/h4\u003e\n\u003cp\u003e\n  Here's the physics, quick and painless: the more pressure you put on a cooling system, the higher the\n  temperature your coolant can hit before it boils. Bump the pressure up to 1.9 bar with this cap and your\n  coolant can climb about 35°F higher than it could before it turns to vapor. That matters because once\n  coolant starts boiling, you get cavitation, little vapor pockets that stop pulling heat out of the\n  engine, and that's when temps spike on you fast. Keeping the coolant liquid longer means it keeps doing\n  its job, absorbing and carrying heat away, right when the engine's making the most of it. In a hot\n  climate or under race conditions, that's the difference between a car that holds temp and one that's\n  creeping toward the danger zone every session.\n\u003c\/p\u003e\n\n\u003ch4\u003eBuilt For 42mm Necks And SpeedFactory Fill Pots\u003c\/h4\u003e\n\u003cp\u003e\n  This is where you've got to pay attention before you order. This cap is made for standard 42mm radiator\n  filler necks and SpeedFactory's Race Cooling System fill pots, and the plunger on it is a good bit\n  larger than the plunger-style caps you'll find on a lot of Honda and Acura chassis from the factory. So\n  this isn't a universal swap for any Honda cap, it's built specifically for the 42mm setup. If you're\n  running a SpeedFactory race fill pot, it's a guaranteed fit. If you're putting it on a radiator neck,\n  make sure that neck is the 42mm size before you buy, because the wrong neck size and the cap won't seal\n  the way it needs to.\n\u003c\/p\u003e\n\n\u003ch4\u003eWho This Is For\u003c\/h4\u003e\n\u003cp\u003e\n  If you're tracking the car, autocrossing it, or just daily driving somewhere that gets brutally hot,\n  this cap is cheap insurance for your cooling system. It's especially worth it if you've already done\n  cooling upgrades like a bigger radiator or a race fill pot, since the higher pressure lets the rest of\n  that system work to its potential. Just know going in that 1.9 bar is a lot of pressure, so your hoses,\n  clamps, and radiator all need to be in good shape to handle it. On a tired old cooling system, sort the\n  weak links out first, then add the cap.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpeedFactory 1.9 Bar high pressure radiator cap\u003c\/li\u003e\n  \u003cli\u003eRaises coolant boiling point by roughly 35°F\u003c\/li\u003e\n  \u003cli\u003eLarger plunger than factory Honda\/Acura plunger-style caps\u003c\/li\u003e\n  \u003cli\u003eFits standard 42mm radiator filler necks\u003c\/li\u003e\n  \u003cli\u003eFits all SpeedFactory Race Cooling System fill pots\u003c\/li\u003e\n  \u003cli\u003eHelps prevent cavitation under high heat and race conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: SpeedFactory 1.9 Bar high pressure radiator cap for standard 42mm radiator filler necks and all\n  SpeedFactory Race Cooling System fill pots. Increases cooling system pressure to raise the coolant\n  boiling point by roughly 35°F, helping the system absorb and dissipate more heat and preventing\n  cavitation under high temperatures and race conditions. Features a larger plunger than the factory\n  plunger-style caps used on some Honda and Acura chassis, and is designed specifically for 42mm necks and\n  SpeedFactory race cooling setups, not as a universal replacement. Confirm your filler neck is 42mm\n  before ordering. One radiator cap per order.\n\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n Universal*\u003cdiv\u003e\u003cspan style=\"font-style: italic;\"\u003e*Fits SpeedFactory Race Cooling System and 42mm Filler Necks Only\u003c\/span\u003e\u003c\/div\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Radiator Cap\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"SpeedFactory","offers":[{"title":"Default Title","offer_id":45789119283234,"sku":"SFR-06-081","price":34.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/SFR-06-081_718t.jpg?v=1781644703","url":"https:\/\/www.hybrid-racing.com\/products\/speedfactory-racing-1-9-bar-high-pressure-radiator-cap","provider":"Hybrid Racing","version":"1.0","type":"link"}
