Not just available in their intercooler kits now, Cobb offers their performance shifter weight to anyone looking for improved shift response. Reducing the weight of the shifting system by over 0.66 lbs will benefit you with improved shift speeds and the overall feel of shifting. The specific size and shape of the CNC machined weight make it extremely easy to install and also adds clearance for front-mounted intercoolers and cold-air intakes that pass through that area of the engine bay.
