One question on the hydro lock thing, any ideas on where the water comes from, wheel well or does it get blown in from the front? And if it only from really deep puddles those must be pretty freakin deep, eh?
as gjgts said (1 post up), you pretty much have to submerge it. this can be from a deep puddle, but it can also be from a relatively shallow puddle if its long enough (or if you hit many in a row). if the water thrown up from your wheels is "thick" enough, this can cause hydrolock.
hydrolock is NOT common though. if it does, it is usually
from driver error. it's pretty hard to experience hydrolock with a CAI
...just pay attention and slow it down when the roads are wet
