SLP Lid Question
1) It appears to be just as sturdy as the stock lid, which is nice.
2) The hole going towards the MAF is shaped like an oval, just like the regular stock lid. I am quite positive this is per GMs requirement that the lid was to work properly with the stock MAF (not throw all the trims off like the aftermarket lid). I would recommend the Blackwing lid over a regular SLP lid if you are worried about fueling issues. I think it would be easier to tune too.
