Another Intake Manifold!

Wellp, let's see... last year my '98 Vic got a new intake manifold last year at about 126,500 miles, Ma's '99 Town Car got one at about 82,000 miles, and now this weel Todd's mother's '06 P71 got one at about 140,000 miles.  Mine lasted a long time if you go by age, Mom's didn't last long if you go by miles.  The '06 just makes things more confusing!
