I agree, I have KBs custom intake and I'm very impressed with its performance. My fan appears to run less than with the stock intake.TxChristopher said:In the long run it would be a smarter move to go with killerbee's intake mod or some other modification of the stock box. The performance is similar to the 06 box but the cost and availability of the 06 air filters will burn you over the long haul. The 06 box also will come from GM with temperature alarm alterations that will not let you know if you have a cooling problem until it is too late.
No codes ever.
