Small V-6 and 4 cylinder engines put out by GM in the early 2000s would overheat easier than earlier year engines... So they put em in the large selling small cars and S-10 pickups... Ford couldn't be outdone...In the early 2000s... Ford started putting plastic intakes on the 302 engines...Mustang, Crown Vic, T-bird, Cougar... HIGH performance...Run em hard just don't get 'em hot... Anything to help achieve better brand loyalty...LJ
