These are take off from a parted sled and in like new Used condition and ready for install and use. Replaced wire out and damaged reeds and provides more Horsepower and throttle response. The biggest positive it getting rid of the factory rubber intake boots that crack and fail causing lean running conditions.
The machined aluminum body will not fail and the rubber boot that attaches to the carb is durable and low cost if needed to be replaced instead of the fragile factory rubber boot.
