Reply to "Air cleaner help."

Mike, as I remember your intake (from Dennis Quella's Pantera Performance), it is a two-piece unit that bolts individually on each cylinder head, with a separate valley cover. Roger initially had problems holding a consistent idle speed, until he found that his aluminum heads and intakes were expanding enough with heat to pull on the cross-link attaching the right throttle body to the main cable. The fix was the custom steel center brace that sufficiently tied the two banks together so heat expansion would not pull on the right side throttles. So even if the brace is interfering with the custom air cleaners, do not remove it or the idle speed will creep from 900 to 1300 rpms as the engine gets warm. The spacing within each intake section is 'std' 48IDA Weber.
