Second generation Firebirds & Trans Ams hit the streets in 1970 with big cubic inch, high-horsepower engines that often struggled to keep their cool in the hot summer months. To make matters worse, most of these cars were modified for even more horsepower and performance before their paint was even dry, creating challenges for the enthusiast. AFCO Direct-Fit radiators are designed to handle these high-horsepower engines with a 20% increase in cooling over the stock four-row radiators.
