well with WAI you have TB -> coupler with 2 grommets -> MAF -> Coupler -> short angled tube -> coupler -> filter
so yea, 3 pieces of rubber, one piece of metal tubing, and a filter.... i'm not sure if you can say that it's "reliable" or "unreliable" or how you'd even classify that.. you know what i mean?
but yea, you'll get the most "gain" you can out of a WAI (or even CAI in my own personal opinion)
