that isn't 'cheap stuff'. its two different products, on two different levels. The dinan option is a 'high flow throttle body' and is dyno-tested, higher quality, well-known, probably yields maximum HP gain, etc..

the aFe option is just a simple 'throttle body spacer' as the name states, , which may yield gains, not extremely high though. this thread is to try and inquire if the gains are significant enough to go with that option, or if its better off to leave it.
