Review on 🚀 aFe Power 46-34008 Silver Bullet Throttle Body Spacer for GM Vehicles by Rip Twin

I already have a feedback system, k&n air intake and tuner on my 18 Silverado and this pad has greatly improved the low frequencies. I immediately notice an improvement in launch and throttle response. I don't notice anything on the top end, but it might be different on a production truck. I haul a lot of weight and it made a big difference when I took off with the trailer. For me it was worth the money and I will probably try them on my other cars. I don't know what it means for fuel economy, I don't track my mileage.
