No, No isues other than tight bolts. It bolted right up nicely. I am very happy with this mod. $$$ well spent. It really compliments intake upgrades. Spent some time reworking the maf yesterday. Opened up the k&n to slide right over the maf adapter. Butt dyno is really happy. I think I'm going with the proflow 80mm precalibrated maf next. bwahhhhhhh
