We've received a few questions about the hood seal on our air box sometimes appearing creased in two areas. Here is an explanation...
The air box has its two most abrupt changes in those two areas which causes the bulb of the hood seal to crease when the seal is fully engaging the air box edge. The hood seal is not glued to the air box - it simply "sandwiches" the edge of the air box. If you pull the hood seal upwards about 1/8" in the creased area, it will help straighten the bulb and, in most cases, eliminate the crease. The hood should then push the areas down as needed during closing.
Along the same subject, you can use a similar technique if you question the contact of the hood seal and hood. You can go around the perimeter of the hood seal raising it 1/8". Next, close the hood and push down gently on the hood in the air box area. This isn't a necessary step, but it may give some of you peace of mind. The technique of sealing to the hood is questioned by many and rightfully so. Most intake systems using this technique don't effectively seal to the hood. The ones that don't are usually obvious because the top edge of the air box doesn't appear to be contoured the same as the hood.
With our systems, we seal to the hood any time we can. This technique provides all of the advantages of a lid. Additionally, it maximizes air box volume and allows us to package a larger filter. Rest assured, if we couldn't effectively seal to the hood, we would use a lid just as we did with our 2014-16 Chevrolet SS sedan air intake system.
