I was curious if I should just add a spacer or should I spend the extra money and replace the whole throttle body all together? Is there a lot bigger gains if you replace the whole throttle body?
Everything works together, on a stock car the plenum spacer is going to have the best benefit. On a car with headers, cams , higher rev limit etc etc, the NWP throttle body will help out.
