not sure about the OP, but mine doesn't move at all with the pins in place of the bumpers. it's all nice and snug.
i was a muscle fanatic before I got into 5.0's and to me the hood pins are a cool sort of throwback to some muscle cars, while being fully finctional.
I have one and you will be very disappointed by the fit. The air seal from hood to filter box is poor. The cone filter has no metal mount at all, and will be difficult to clean. There is no baffling to divert water away from the filter in a rainstorm, and there is no drain for the water the scoops suck in.. The overall design is so poor I wouldn't use it at all without serious modification. Top that off with the fact I could not get it to run correctly with either a stock 55 MM or a 70 MM 95 Mustang MAF. Both MAF's work great with a stock airbox on the same car.
Thanks for the heads up. BTW.. the Cervini rep said the box they sell has a drain hole in it for the water, but I did notice that there is no shielding on the top, so any junk or rain will run right into the filter. Seems any baffle would interfere with the air flow, negating the ram air effect? I already have a K&N FIPK filter which I was going to use.
I'll stick with the BBK CAI setup then. I doubt there is much of a hp difference between the two and not worth the $100.
I'm really shocked the hood don't move around. I do not have any pieces left over. I liked the idea of the box, I loved the full throttle sound of the thing sucking air thru the hood. I hated the corroded alternator, intake, brackets, etc from the water. I actually ran the hood without the ram air for a while and it was a watery mess under hood. I felt even though the air box was a poor design and didn't seal well, the part that attaches to the underneath of the hood saves some mess from the scoops. But when you lift the hood, wooooosh. Its 6 of one half dozen of the other. My car was a black show car and it looked like crap under hood no matter what I did. I take it you bought it used? It has the under hood part but not the air box. Mine all came in a kit separate from the hood. I had to put that air collector on the underside of the hood.
Yeah I bought it used for a screaming deal of $200 painted, so I couldnt pass it up. I've owned this hood before without the airbox kit and didnt have that much of a mess under hood, but I also clean my engine once a week when I wash it. The hood is snug as a bug. I put a small rubber washer on each pin and with the pressure of the hood and the lock pins it is very secure.
