5.2/5.9 V8 High-flow 4" Air-Intake system & 52mm Bored-out Throttle Body = Major Differance!

Bought a super nice CNC Machined dual 52mm bored out throttle body (big improvement over the stock restrictive necked down 48mm one), then installed a beefy and huge 4" Spector brand Low-Profile Aluminum High-flow Top-hat to fit it, and then 4" Aluminum tubing & 4" High-flow ait filter & underhood Heat-shield... It REALLY opened things up, especially in the throttle response & lower RPM torque at take-off...
