Been driving with BC 264s for a year now, 15,000 miles later, still no CEL, solid AFRs everyday and such a blast to drive. My full BC head package is wonderful and brought new life to the car. By far the best mod i have done to my car in the over 3 years I have owned it. Do not even think twice about installing these cams. An intake and exhaust combo costs just as much and cannot beat the performance at all, get these and worry about supporting mods after!
