Based on actual track testing, this single pass design outperforms the triple pass design often seen on ND aftermarket radiators. It's very similar to the single pass radiator design that we used in our 15 hour test at Laguna Seca, where our turbo ND car ran cool despite running every session of a two-day weekend.

All-aluminum construction - no failure-prone plastic end tanks here! - with a focus on efficiency instead of just pure size.
