To spec., because there's a specification for a reason. Once in a while you have to go by feel because a torque wrench simply won't access the bolt or nut, but if you've been doing this (working on cars) long enough you develop a feel for torque. In fact the last aftermarket intake I did, I didn't use a torque wrench at all, I followed the torque pattern of course, but went with "snugged the f**k down" as my spec. :thumbsup:
