This is the most complete Option B kit on the market. Comes complete with everything needed to install on your car so you won't have to make any extra trips to the store. This kit works but constantly bleeding air from the intercooler system, and it makes flushing the system a snap! The extra capacity of coolant also helps with heat soak.
Includes: Coolant tank and cap, tank mounting bracket, one T fitting, three feet each of 3/4" and 1/4" hose, six hose clamps, air bleed fitting, one brass hose barb.
Fitment: Kit is designed to fit Cobalt. Will fit Ion but will require you to modify mounting bracket.
