Looking for a little extra pep from your GM truck? This 1-inch thick throttle body spacer might be worth a look. It's made from CNC-machined aluminum (anodized red for a sporty look) and fits between your throttle body and intake manifold on Chevy Silverado 1500 and GMC Sierra 1500 trucks with the 4.8L, 5.3L, or 6.0L V8 engines.
