for sale despite being in second place,
Callaway X2 Hot Pro Irons Price

Revised valves are available to solve the problem,
Titleist AP2 714 Irons Price, and the bulletin notes that vehicles built before VIN 5B406012 may already have the new intake valves installed. That coupled with the six other problems I have had with this car in the past year (including a full on radiator replacement) makes me about 3 days shy of proclaiming this car a lemon. Good luck to you.
