Their all-aluminium unit, for manual cars, has a two-row, triple-pass core, so the coolant crosses it three times, built from B-Tube cooling tubes behind multi-louvred fins. The quick-connect inlet and outlet and the brackets are CNC-machined, and there is an aluminium drain plug.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-row, triple-pass core: coolant crosses it three times\u003c\/li\u003e\n\u003cli\u003eB-Tube cooling tubes, about 15% more tube surface than plain oval ones (CSF)\u003c\/li\u003e\n\u003cli\u003eCNC-machined quick-connect inlet and outlet and brackets\u003c\/li\u003e\n\u003cli\u003eAll-aluminium, with an aluminium race-style drain plug\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCheck before you order\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eManual cars with Audi radiator 8D0 121 251 AP only.
