I WAS TRYING TO USE MY SMOKE MACHINE TO FIND A VACCUM LEAK IN MY CHEVY LS 5.3L ENGINE. YOU SHOULD SEAL YOUR INTAKE AS CLOSE TO THE AIR FILTER AS POSSIBLE SO THAT THE INTAKE TUBE AND MASS AIR FLOW SENSOR GET TESTED AS WELL. I USED THE TAPERED CONES, BUT THEY ALWAYS CREEP OUT OF THE BOOT. SO I FINALLY MADE THIS ONE. WORKS GREAT.

NO AMS

NO SUPPORTS OR BRIM NEEDED.

FAST EASY PRINT

I PRINTED MINE ON THE A1 MINI
