Full aluminum construction, Nocolok-brazed core bonded to hand-crafted, heliarc-welded polished end tanks — this isn't a mass-stamped radiator, it's built the way a real cooling system should be.\u003cbr\u003eThat 53mm core means real capacity — up to double the coolant volume and as much as 35% more cooling performance over your tired factory radiator. Whether you're daily driving or putting laps down at the track, this is the reserve you want in the system when things get hot. True OE-spec mounting means it drops straight into your factory location, no cutting, no relocating, retains your stock fan shroud mounts — just a clean, direct bolt-in.\u003cbr\u003eImportant: this radiator is manual transmission only, and your factory radiator cap will NOT work with it — you'll need the Koyo SK-C13 cap (or equivalent) to complete the install. Don't skip this part, or you won't be running proper system pressure.\u003cbr\u003eBut this isn't just about a bigger core. It's about a 2JZ that stays in its happy zone when you're actually pushing it — the difference between a car you can drive hard and one you're babying around every hot lap. Whether you're building a serious track Supra or just want peace of mind on a spirited drive, this radiator does exactly that.\u003cbr\u003e🚚 Fast shipping nationwide — orders ship next business day, typical arrival in 2-4 days\u003cbr\u003e⭐ Local pickup available — Pico Rivera, CA showroom\u003cbr\u003e📞 Questions on fitment or install?
