What was found
DURING ROUTINE OIL CHANGE, OBSERVED AIR INDUCTION FILTER 'LAYING' IN ENGINE BAFFLE. UPON FURTHER INVETSIGATION, FOUND BOTH MOUNTING BRACKETS HAD BROKEN/SHEARED FROM THE INDUCTION FILTER BODY. SUSPECT CAUSE, INADEQUATE METHOD OF ATTACHMENT OF BRACKETS TO FILTER BODY/ASSY. SUBMITTER STATED METHOD OF ATTACHMENT APPEARS TO BE 'SPOT WELDS'. PERHAPS RIVETING OF THE BRACKETS TO THE FILTER ASSY MAY BE MORE SUITABLE.
