Actually, I just checked Lowes, knowing SOMEONE had to have quick release straps that are not ridiculously priced. $21
per strap is almost unconscionable for the purpose it serves and for a car that isn't worth over $8-10K, nyet?
Lowes has a pair of quick-release, adjustable duct clamps for $5 that clamp up to 12" diameter ducting (therefore prob measure about 14" I'm thinking.
I would NOT use them to to wrap totally around the plenum + box, but instead cut the end off about 5", loop that one end through one of the original clamp slots in the plenum so that the end folds back onto itself (and therefore held in place not only by the fold in the strap, but by the pressure of the outer strap upon it.
Similarly, loop the other cut end through the opposite plenum slot and back upon itself. Then join the free ends over the top of the filter box, screw together and tighten.
To release, just flip the screw up (quick release).
Might have to be slightly longer than 12", but I'll get a pair and try it out.
Addendum: Actually, when I measured the partial circumference from hook's slot over the top of the air box, to opposite side hook-slot, it was 12". Leaving 3" overlap of the strap at each hook-slot, plus about 2" for the screw to fasten, that should mean about a 20" strap.
