For the money I'd say the gains are worth it. I'd say there's a 5° increase in coolant temperature

Worth every penny!
04 Impala SS 3.1 pulley double stack IC cai base tune with 3 in down pipe. Definite increase in engine response off idle, also in the 5000-6000k rpm range it seems to pull better (might just be me) but this bolt on is 100% worth the money. It’s amazing the weight difference when comparing the old pulley to this one. I jumped up a half size on my serp belt work mint! BUY IT!

Easy first mod
Easy install for quick gain in hp I’d recommend a lower degree thermostat and make sure you order the proper belt size
Pulley slaps right in a
Pulley slaps right in a lot lighter then OEM product. Noticed different idle and faster throttle response would definitely recommend one of these bad boys
